Where Horizonis going.

What is being done, what comes next, what shipped and where you can help. No dates: things are Now, Next or Later. Read it in plain words, or switch to the technical picture.

Horizon is Minecraft: Java Edition 26.3 rewritten from scratch in Rust, so it runs faster on the same computer. Single player, LAN, servers, resource packs and Horizon's own mods work today, on your own copy of the game.A native Rust and wgpu reimplementation of Java 26.3: the same saves, rules and terrain, checked against the real game by more than 300 differential harnesses (a Java oracle and a Rust probe on the same inputs). Single player runs on its own server thread, like vanilla's integrated server.

Being done now

  1. 01Steady frames at long render distancesMaking Horizon faster than vanilla on every computer, with smooth camera movement even at 32 chunks, by spreading the work better over the processor's cores.Frame pacing at render distance 32 (#678): long frames come from work competing with the render thread. In review: no main-thread tick stutter at high render distances (#3827), each proto chunk's light view built once (#3815), video memory handed back by the vertex arena (#3466), chunk batches assembled on helper threads (#3036), free structure starts in the generation workers (#1760). Still open: far terrain at 48 to 64 chunks (#718) and CPU-bound fields of block entities (#717). Every change shows before and after numbers from tools/perf_bench.py against vanilla 26.3 (docs/benchmark.md).
  2. 02Modpacks' world generation, nativelyMaking the world-generation mods of popular modpacks (new structures, YUNG's dungeons and mineshafts, packs built on Lithostitched) generate their worlds in Horizon, natively and fast.horizon-port-pack carries a pack's data-driven content over, and 26.2 data packs are upgraded to 26.3's format (#3369). In review: worlds taller than 32 sections and each level's shape from its dimension type (#3480, #3488), data-pack biomes in local and remote worlds (#3491), block state providers (#3802), surface rules by biome id (#3366), Lithostitched's pool and processor modifiers (#1777). Mods whose Java code does more than world generation don't run (docs/modpacks.md).
  3. 03Single player as a server: the last differencesSingle player now runs a small server in the background, as vanilla does. We are fixing what still behaves differently there; every fix also works for LAN and server players.Since #1514 single player runs on the server thread (game/integrated.rs) and the window joins it as a client. The open [server-thread] issues list the gaps. In review: breeding's advancement and statistic (#3873), the client's menu when the server replaces the player (#3841), splashes when falling in water (#3621). docs/server-levels.md.
  4. 04Vanilla parity: the player-visible gaps, closedEvery method of the Java game is tracked with where Horizon does it, and the differences players can see are being closed, list by list: mobs, blocks, items, screens, rendering, servers.The port ledger (tools/port_ledger.py, tools/port_map/, #3139) gives every 26.3 method a verdict and links the harnesses that cover it (#3526). The player-visible gaps are ten lists, one per area (#3512 to #3521); a fix translates the vanilla method, ticks its row and carries the parity label. Start from .claude/skills/vanilla-parity.
  5. 05ModsMods for Horizon, as one line of work led by the modding team: native mods the launcher builds into your game, mods on servers, mod screens and settings, tools for mod makers, the registry and machines.One item for all modding work (#3911), led by levzzz5154; the order between the parts is theirs. Native mods on stable hook points (game/native_hooks.rs, #3345, #3346, #3434, #3435) built by the launcher (#3388, #3855); server-side hooks (#3878, #3706); mod-owned screens, input and drawing; tools for mod makers (templates, native.py check); the registry (#1634, #1642, #1659); machines with inventories and menus (#1189); mods that read and change the world through the server. docs/native-mods.md.

  1. 01Fresh benchmarks against vanillaNew public numbers comparing Horizon with vanilla on many kinds of computers, measured the same way every time, with a history that shows what each release changed.Redo the comparison after the current performance work (#1073); reliability, coverage and presentation (#1346); a scene must count as loaded only once its first chunk arrives (#1749). Next: a performance history across releases (an automatic comparison of each release with the last, on a timeline), more report fields (server TPS and MSPT, power, battery drain, temperature, throttling) and more hardware (a MacBook on battery, low-end laptops, community reports). Players' reports come in through --benchmark and horizon-launcher data benchmark (docs/benchmark.md).Performance
  2. 02Faster world creation and entry on small CPUsCreating a world and joining it should be quick even on a four-thread laptop, where a fresh world at 32 chunks can make you wait minutes for the first terrain.Cut the per-column generation cost (noise sampling, surface rules, aquifers) and the lock convoy on structure starts, and leave one core free for the rest of the game as vanilla does (#1760 and #1778, in review, are listed under 'Steady frames at long render distances'). Still to profile on small CPUs: the first seconds of a fresh world deliver no chunk, and fluids remesh for about a minute after loading. Measured with tools/perf_bench.py (docs/benchmark.md, docs/profiling.md).Performance
  3. 03Low-end computers: Steam Deck, old Macs, 8 GBHorizon should run well on small machines: integrated graphics, the Steam Deck, older Macs and 8 GB of memory, with a battery mode that saves power on laptops.Partly done: an opt-in 60 FPS cap with fewer workers on battery, Far Detail Reduced for integrated GPUs and animated textures on the GPU (both shipped). Left: measured targets and fixes per class of machine (memory use, worker counts, startup) on a Steam Deck, old Intel and Apple Silicon Macs and 8 GB computers, reported on the Benchmarks page.Performance
  4. 04Native upscalingDraw the game at a lower resolution and sharpen it to your screen's size, in the way of FSR or DLSS, to gain frames on weaker graphics cards. An optional graphics setting.A render-scale setting below the window size with an upscaler of our own that runs on every wgpu backend. Proof: frame time against native resolution on integrated GPUs, and screenshots for image quality. Issue #1403.Performance
  5. 05Server console, bans and a full admin APIManage a server from a console, ban and pardon players, and drive it from other tools through a full admin API and an MCP server for AI agents.horizon-server console (a text interface), ban, pardon, ban-ip and mcp over stdio. Admin API additions: the player list, kick, ban, op and whitelist, an SSE stream of logs and events, a text metrics endpoint, config GET and PATCH, backup delete and download. The last pieces merged: bans edited while the server is stopped (#9767) and the MCP tools' contracts pinned by a test (#9748). The panel's later features and vanilla's management protocol are their own item (server-panel-management). docs/server.md, docs/api/server.md.Servers and multiplayer
  6. 06Hosting polish: Windows service, safe updatesSmoother hosting: a real Windows service, a backup before every update, backups that keep the world and each player's state, and a changed view distance or message without a restart.A Windows service wrapper instead of the logon scheduled task; backups.before_update; hot reload of config for view distance and the message of the day (needs engine support); backups that keep world and player state (#1808, a contributor's draft, in review). docs/hosting.md, docs/server.md.Servers and multiplayer
  7. 07One single-player path: remove the in-frame worldSingle player has one way to run, the server thread, so every fix works everywhere and there are fewer bugs. The older in-frame mode is removed.--in-frame (also --no-server-thread and HORIZON_SERVER_THREAD=0) ticked the world inside the window's Game. #6473 removes it with the code only it reached (the window's world loader and player tick, its portal travel and loading screen, the in-frame LAN host); the harnesses run on the server thread. See also 'Single player as a server' and docs/server-levels.md.Gameplay parity
  8. 08Faster block lookupsSpeeding up the code that reads and writes the blocks of the world, which almost everything in the game goes through: generation, lighting, meshing and ticking.PalettedContainer and PackedStorage find an entry's word by multiply and shift instead of an integer division (#1790, #1794); meshing looks up baked models by index, not by name (#1747). Each change keeps the paletted storage harnesses identical and shows its microbenchmark in its pull request.Performance
  9. 09Playing on servers: everything shows as it shouldWhen you play on a server, other players, mobs, items and menus look and behave as in vanilla: skins, poses, item names, inventories and server networks.Client-of-a-server fixes in game/remote*.rs and horizon-protocol: mobs' aggressive and item-use flags (#1802, #1798), ghost items after a remote menu (#1795), skins (#1652), cookies and transfer packets for proxy networks (#1650), firework boosts (#1671), living-entity attributes and simulation distance (#1731), styled item names (#1702), primed TNT between updates (#1710).Servers and multiplayer
  10. 10Shader packs, written again from scratchShader packs were removed and are being rebuilt from scratch. They come back, off by default, once the best-known packs draw properly.A clean-room rewrite in horizon-shaderpack, from the packs' public format documentation only: reading packs, the preprocessor and .properties files are merged (#1584, #1585, #1586); translating programs to WGSL through naga, buffers, uniforms and the terrain, entity, sky, weather and hand stages are in review (#1698 to #1801).Rendering
  11. 11A new launcher designA redesigned launcher: every button where you expect it, the fewest clicks to play, add an instance or add mods, smooth animations, and instant startup.Based on the site concept by the Team (Bricolage Grotesque, a night sky and an animated pixel sunset). Screens and flows are designed first, then small PRs; tokens in crates/horizon-theme and rules in docs/design-system.md, the game's vanilla look unchanged. Measured before and after: startup, frame time and idle CPU/GPU, reduced motion honoured. Mods screens separate Horizon native mods from Java mods; a running instance can be stopped from the launcher.Launcher
  12. 12SplitscreenPlay with a friend on the same screen, each with a controller.Issue #2054, built by martipops as a series: up to 16 local players on the server thread's multiplayer (#3541), each controller driving its own player (#3794), joining with a controller (#3801), players in windows of their own (#3825) and the profile page (#3826).Gameplay parity

Servers that hold 20 TPS with 50 to 100 players

Servers that keep 20 ticks per second with 50 to 100 players. Today Horizon holds it up to 50 bots and drops to about 10 at 100.Measured against vanilla on equal work (docs/server.md, Scale): Horizon is ahead with few players and when exploring, but vanilla's tick is shorter with 25 to 50 players near spawn. Ideas on the list: send entity changes instead of rebuilding every entity each tick (about 15 percent), fewer memory reads in random ticks and collision scans, cheaper item collision checks, mob AI and natural spawning. The bot benchmark (horizon-bots) is the proof.

Modpacks

Older Fabric and Forge mods

Recognise mods built for versions before 26.1 in the mod browser, so they can be checked and carried over like newer ones.A mapping table from intermediary and SRG names so pre-26.1 jars can be classified, and a rename for mod ids with dashes (fabric-api); the port step then treats them like newer jars (docs/mod-browser.md).

docs/mod-browser.md#10262

Modpacks

A modpack's own resource and shader packs

Imported modpacks carry their resource packs into a profile of their own. Shader-pack conversion is still pending.Resource-pack carry-over is implemented locally: Modrinth common/client overrides, CurseForge's override folder, installed instances (ZIP and directory packs), and hash-checked indexed ZIP downloads. The launcher keeps profile edits and lets resource-only profiles play; packs are enabled in Resource Packs. Synthetic import and profile tests cover the file pipeline; in-game rendering has not been verified. Shader-pack conversion is still pending, so this combined item remains partial (docs/modpacks.md).

Whole modpacks, such as ATM10, rewritten

Rewriting a complete big modpack for Horizon so it runs far better than the original. Not a priority now: the work above comes first.The project's first goal for modpacks: support them ten times better than vanilla and port any of them. It was set aside in favour of compatibility through the browser. What exists: ATM10's world generates and 42 of its 496 mods are carried at least in part (docs/modpacks.md). It depends on 'Mods with code' and the native mod API.

Running Java mods that aren't rewritten

Run Java mods that nobody has rewritten for Horizon yet, through a bridge or a converter. Hard and not started: the Convert button and native rewrites come first.Earlier research (#527, closed) found that Java mods can't simply run, because they call Minecraft's own classes. Option to look at again: a bridge for simple Fabric mods.

CurseForge in the mod browser (coming soon)

Coming soon: search and download CurseForge mods and modpacks from the launcher, as you can with Modrinth today.The mod browser lists CurseForge as coming soon (docs/mod-browser.md): it needs CurseForge API access. Meanwhile packs import from a CurseForge zip or instance folder, and jars only CurseForge hosts come from the player's own instance (docs/modpacks.md).

Modpacks

A Convert to Rust button for what isn't rewritten yet

When a mod, shader pack or modpack hasn't been rewritten for Horizon, one button converts what can be converted, so you don't have to wait for the rewrite.Generalise the mod browser's Port step (horizon-port-pack: the data, assets, worldgen and block and item definitions of Java mods, .mrpack and CurseForge zips) to every kind of content: code mods as native mods (see 'Mods with code') and shader packs, converting an Iris/OptiFine pack into Horizon's format. The browser says what works before the install. Java code itself does not run (docs/modpacks.md, docs/mod-browser.md).

Mods with code: machines, magic, mobs

Making mods that add machines, magic and mobs work in Horizon, in steps, starting with machines. They are most of what a big modpack is made of.333 of the 496 mods in a big pack (ATM10) contain code. Issue #1854 ranks the gaps (ticking block entities, networking, rendering, menus, inventories) that unlock them in tiers, with machines first as the recommended path. Code mods are native mods now (docs/native-mods.md): each port is a horizon-mixins bundle. The path isn't started yet (docs/modpacks.md).

Modpacks

Data packs in the mod browser

Search and install data packs from the launcher's mod browser, for the world you choose, as you do mods and resource packs.A Datapacks tab beside Mods and Resource packs: install into a chosen world's datapacks folder, with the same checks and 'works in Horizon' notes as the other kinds (docs/mod-browser.md).

Servers and multiplayer

Server panel extras and vanilla's management protocol

More of a server managed from its web panel (bans, worlds, logs and crash reports, modpacks), and vanilla's own server-management tools working with a Horizon server.The panel's later features (bans, worlds, server.properties import, logs and crash reports, modpacks) and vanilla's management protocol (the JSON-RPC over WebSocket that the management-server-* keys configure), so vanilla's tools can manage a Horizon server. Split from server-admin. docs/server.md, docs/api/server.md.

Servers and multiplayer

Join servers on older versions

Join servers that run older Minecraft versions, such as 1.21 or 1.8 PvP servers, from Horizon.Asked often in the suggestion queue. Horizon speaks 26.3's protocol; the path is a native protocol adapter in Rust that translates older versions' packets, not a downloaded Java proxy. Java instances in the launcher already play any version with the real game.

#3023

Servers and multiplayer

Online-mode checks for Play with Friends

Friends who join through an invite code could prove who they are with their Microsoft account, as on online-mode servers.Play with Friends joins over an encrypted tunnel with an invite code (docs/play-with-friends.md, 'Identity'). Online-mode checks against Mojang's session servers can be added on top of the same tunnel; they need Microsoft sign-in first, which is coming soon. Play with Friends stays self-hosted between players, with no relay run by the project.

Servers and multiplayer

Prepare a version without Java

Set up Horizon, a server first, without Java on your computer: published tables are combined with your own copy of the game.Today horizon-prepare runs Mojang's exporters with Java. Issue #1750 proposes publishing the computed version tables once from CI and assembling the rest locally from the player's own jar and assets, provided the tables hold no Mojang content; a contributor offered a pull request, and it would help phones too. A server-only prepare from server.jar alone is the first step (docs/server.md).

#1750docs/server.md

Servers and multiplayer

Guided hosting with Tailscale and an invite button

In the launcher, a guide and a button to host a server and invite friends over Tailscale, so nobody has to open ports on a router.On the Servers page (create, start, back up, update and invite are shipped) add a Tailscale setup that explains and checks each step, and an invite button that hands friends what they need to join over the tailnet. Buttons first, no docs needed, with the details in an Advanced section. Remote access over Tailscale is already described in docs/server.md.

An official Docker image for servers

An official image to run a Horizon dedicated server in Docker with one command, your own copy of the game files mounted in.The repository has the Dockerfile (packaging/server/Dockerfile: a multi-stage build on Debian bookworm-slim, user horizon, volume /data, port 25565, game files mounted read-only, HORIZON_EULA and friends answering the first-start questions), and anyone can build it (docs/hosting.md, section 9). Left: publish the image to a public registry from the release workflow, tagged per release, so it follows the same checks, and update the docs and the launcher. The image never holds Mojang's files.

Servers and multiplayer

A server you install with one command

Install and run a Horizon dedicated server from a terminal with a single command, no launcher needed, for VPSes and headless machines.A player's idea (#horizon-ideas). horizon-server already runs headless; left: an install script (Linux/macOS shell, Windows PowerShell) that fetches the signed release, checks it, asks for or points at the player's own game files and starts the server, documented in docs/hosting.md.

Ready-made setups for hosting panels

Install a Horizon server from the panels hosts use, such as Pterodactyl and AMP, the usual way for each panel.Asked in the suggestion queue for Pterodactyl eggs and AMP templates. Builds on the one-command install ('A server you install with one command') and horizon-server's server.toml (docs/hosting.md).

Scripts for mods

Small mods written as scripts, in the style of KubeJS, with no compiler.Waits for native mods to settle: a script layer over the native hook points is to be designed.

Mods and API

Orbital Laser on the normal game

The community mod Orbital Laser, made for a fork of Horizon, running on the normal game as a native mod and listed in the registry.A native port (a horizon-mixins bundle, docs/native-mods.md) of https://github.com/Stink-O/orbital-laser (MIT), which today runs through its author's fork. Tested in the game, and listed in the registry.

Mods and API

Native versions of popular client mods

Built-in versions of the client mods players ask for: block info on hover, a world map, inventory tweaks and schematic overlays.Done: a mod list and menu, minimap, zoom, keystrokes, an FPS counter and a recipe viewer, as native mods (horizon-mods/native/). Asked for: an angled world map that shows hills, overhangs and caves, inventory tweaks (drag and scroll to move items), block info tooltips and schematic overlays.

Mods and API

Create-style physics as a native mod

Contraptions and physics like the Create and Aeronautics mods, as a mod for Horizon rather than part of the base game.Issue #805 (porting QOL mods) closed with this answer: it would come as a native Horizon mod.

Mods and API

Proximity voice chat as a native mod

Hear nearby players talk, as with the voice chat mods of other Minecraft versions, as a Horizon mod.A native mod (docs/native-mods.md). It needs a way to carry voice between players and an audio path in the game before anything can be built.

Gameplay parity

Every Minecraft version, prepared automatically

Every past and future Minecraft version prepared for Horizon automatically. When Mojang releases one, Horizon follows it, and every system is checked against it again.The port pipeline (docs/version-ports.md, tools/version_port.py) detects a release, prepares it, diffs its classes against the pinned 26.3, regenerates the data-driven tables, runs every parity harness on it and writes a port report that becomes issues. The goal is as little human work as possible for any version, past or future. Detection and the first slices are merged; the scheduled agent that runs it every day isn't installed yet. Two versions in one build are out of scope.

docs/version-ports.md#4758

Gameplay parity

Controllers: tested on real pads, and in the launcher

Make controller support solid: tested with real PlayStation and Xbox pads and a Steam Deck, and usable in the launcher too.The game side is merged (docs/controllers.md): pads read with gilrs, menus, rumble, glyphs, remapping and DualSense adaptive triggers, lightbar and haptics, but not yet confirmed on real pads or a Steam Deck (DualSense haptics stay behind a switch until then). Left: a test pass on real hardware, and the same focus navigation in the GPUI launcher.

The full debug screen

Vanilla's complete F3 screen: debug options, a profiler chart, ten-second captures and an atlas dump.Today F3 shows position, chunk, light, biome and FPS (docs/native-client.md). Vanilla also has F3+F6 debug options with profiles, F3+1 the profiler pie, F3+L a ten-second capture and F3+S the atlas dump (#562 asked for the F3 editor).

Choose the audio output device

Pick the speakers or headphones Horizon plays through, in Music & Sounds.An output device list in Music & Sounds, falling back to the system default. #1035 started it: a player on an older Windows computer had no sound at all, and a device choice is how such cases are found and fixed.

Rendering

A light default shader pack

A small built-in look (tone mapping, colour grade, a cheap vignette) that costs almost nothing, for players who want a nicer picture without a heavy pack.An opt-in, composite-only pack on the native shader API, under about 0.3 ms at 1080p, shown on the Shader Packs page. Pack option sliders and profiles, and a Failed row with the full error, belong with it.

Rendering

Optional ray tracing

An optional ray-tracing mode for graphics cards that support it (RTX and recent AMD): shadows, water reflections and global lighting on top of the vanilla look.A spike with ray-traced sun shadows, off by default, is a draft (#1180). Reflections, global illumination, Apple M3 and newer if it is cheap, and a performance report per card come after.

#1180

Rendering

MSAA, anisotropic filtering, exclusive fullscreen

More graphics options: multisample anti-aliasing, anisotropic filtering and an exclusive fullscreen mode. Today Horizon has FXAA and borderless fullscreen.Not implemented (docs/graphics.md). Anisotropic filtering needs linear magnification in wgpu, which blurs close blocks, so close-up sharpness has to be kept first; MSAA would sit beside FXAA, and SMAA or TAA are asked for too; exclusive fullscreen where the backend supports it.

Rendering

Well-known shader looks, rewritten for Horizon

Popular shader packs rewritten in Horizon's format, so good packs exist from the start. Only packs whose licence is open source and compatible with ours are rewritten, never anything else.The first candidates are Photon, Chocapic13 and MakeUp Ultra Fast, each only after its licence is read and recorded: a pack is rewritten only if it is open source and compatible with Horizon's licence, and the rewrite is written from the shader format's documentation and the look on screen, not from anyone's code. Today only the Golden Hour example exists ([crates/horizon-shader-api/packs/golden_hour](https://github.com/horizon-rust/horizon/blob/main/crates/horizon-shader-api/packs/golden_hour)).

docs/shaders.mdcrates/horizon-shader-api/packs/golden_hour

Launcher

Lean installs that use less disk

Smaller installs: Horizon keeps one shared copy of the prepared game files and removes what only the preparation needed.A shared resource store keyed by the preparer's digest, no prepare intermediates left behind, the current and the previous version kept, and an automatic clean-up. Not started.

Launcher

A launcher screen readers can read

Screen readers read the launcher's buttons, lists and settings, and every part of it works from the keyboard.Issue #4537: the launcher is GPUI (not Electron), so it exposes nothing to UI Automation, NSAccessibility or AT-SPI yet. Needs an accessibility tree from GPUI (an AccessKit bridge) and a role and label on each widget.

#4537

Launcher

A visible beta label

A clear 'beta' label in the launcher and the game, so nobody is surprised that Horizon is still being built.Show Beta in the launcher's header and about page, on the game's title screen and on the website, beside the version number (docs/versioning.md).

Platforms

Horizon on Linux ARM64

Game and launcher builds for 64-bit ARM Linux computers.Issue #1709: aarch64 builds of the game and the launcher in the release workflow, tested on a real ARM machine with its Vulkan driver. The server build already drops audio and controllers (--no-default-features).

#1709

Platforms

The launcher builds Horizon on other systems

On a system Horizon has no download for, such as FreeBSD, the launcher offers to build the game on your computer, as it already does for native mods.Issue #4354: when no release asset matches the platform, the launcher fetches the tagged source and runs the same pinned-toolchain cargo build --locked its native-mod builds use, with a warning about the time it takes. The build is unsigned, so the launcher marks the version as built locally.

Horizon on Windows ARM64

A native Horizon for Windows on ARM computers, such as Snapdragon laptops.Releases are x64 for Windows and Linux and arm64 for macOS. Needs an aarch64-pc-windows-msvc build in the release workflow and a machine to test on.

Android, iOS and the browser

Versions of Horizon for Android, iOS and web browsers. Nothing official yet; contributors have started the first pieces.No official build. Android was first closed as not planned, with touch controls, a mobile interface, packaging and loading the player's own assets all missing; the roadmap now includes it, iOS and a build for the browser as long-term goals. First pieces from contributors: horizon-dualsense compiling on iOS (#1813) and helper-thread limits on Android (#1751). Preparing without Java (#1750) matters here too. Horizon ships none of Mojang's files on any platform.

Fixes for Linux desktops that use Wayland and Hyprland: fullscreen, the clipboard, the GUI scale after a restart and the like.Open: the GUI Scale is clamped to 2 after a restart under Hyprland, while XWayland keeps it (#1866). Earlier reports covered fullscreen dropping on menu clicks, the clipboard and a white overlay (#1007, closed). Checked on a real Wayland session.

A Nix flake

Install Horizon on NixOS through a Nix flake.A player's idea (#horizon-ideas). The launcher's AppImage ships with each launcher release (packaging/linux/appimage.sh): one file with the libraries GPUI needs, which replaces itself when it updates. A flake.nix packaging the release binaries with their runtime libraries (Vulkan loader, X11/Wayland, ALSA) is still missing, the way horizon-parity's NixOS setup runs them today.

Horizon extras

A complete video studio inside the game

Record, replay and edit videos without leaving the game: record in a keypress, replay a session, cut and finish the video. One of Horizon's original goals.Three stages. Recording: capture gameplay in a keypress with an encoder thread and little frame-time cost. Replay: a replay mode for recorded sessions. Editing: cuts, camera paths, titles and export. None of it exists yet; the agent-control socket (docs/agent-control.md) already lets tools drive the game for scripted shots.

Horizon extras

Game menus in the launcher's style

An optional look for the game's own menus and options that matches the Horizon launcher. Off by default: the vanilla menus stay as they are.A player's idea (#horizon-ideas). A built-in resource pack or a Horizon setting that restyles the title, pause and options screens with the launcher's design tokens (crates/horizon-theme), following docs/design-system.md; off by default because it changes the vanilla look.

AI and agents

An optional AI teammate

An optional AI teammate you can talk to by voice. It plays beside you, helps or finishes the game with you, runs on your computer first, and exists only if you turn it on. The No AI switch hides it.Draft pull requests: the companion (#1068), its safety modes and their evaluation (#1069) and a route that finishes the game (#1070). In the drafts: a companion that follows, fights, mines, crafts, sleeps and respawns; chat and push-to-talk voice, with speech recognition and a choice of voices; presets (very strong, helper, beat the game); a guard model with Clean, Kid and Salty modes; perception levels from Fair to All-knowing; hardware detection with a simple mode and an Advanced tab; local models first, cloud keys optional. The No AI switch is already in the game. Left: the speedrun route doesn't finish the game reliably yet, voices for more languages, and the safety evaluation, which must pass before it ships.

#1068#1069#1070

AI and agents

A versioned agent-control protocol

A stable, documented way for AI agents and scripts to drive the game and the launcher, with versions and an event stream so tools keep working as Horizon changes.hello answers with the API version, the release and the features; horizon-ctl --api; MCP serverInfo; reply schemas generated into the reference; a test. namespace for hooks; transcript compatibility tests; subscribe as a stream of events on one connection; Horizon option files by key and saved-server commands. Agent control itself (horizon-ctl, both MCP servers, the No AI switch) is done: docs/agent-control.md, docs/api/agent-control.md.

AI and agents

Port mods with your own AI agent

You can port a mod to Horizon with your own AI agent on your own computer. Horizon documents how and gives you the tools, but provides no hosted agents.A player runs their own agent locally with horizon-ctl and the MCP servers (docs/agent-control.md), cargo horizon-mod, horizon-port-pack and the parity harnesses as the check. Horizon writes the guide (playhorizon.dev/docs/agents, docs/modpacks.md) and runs no agents, accounts or keys for players. The No AI switch turns all of it off.

Code and tools

Pipeline protection and a GitHub App for agents

Safer releases: changes to the release machinery need the owner's review, and AI agents use a smaller identity of their own instead of a personal account..github/CODEOWNERS lists the workflows, the release and signing tools, the update-checking code and the installers (#1015); the branch protection that makes it count waits for the horizon-agent GitHub App, which reads and writes code, pull requests and issues but can't change settings, workflows, secrets or members, and whose tokens last an hour. It needs the owner to create the App and switch the protection on (docs/security.md).

docs/security.md

Code and tools

Signed updates everywhere, installers included

Every download Horizon makes is checked against the project's signature, including the first install with install.sh and install.ps1.Releases carry signed checksums, and the launcher and horizon-server update refuse anything unsigned (#1011, #1014). Left: the first install through install.sh and install.ps1 still trusts only the checksum GitHub publishes, because verifying Ed25519 signatures needs OpenSSL 3, which macOS doesn't ship (docs/security.md).

Performance

Benchmark your computer

Run Horizon's built-in benchmark and share the report: every new computer makes the performance work more accurate. No coding needed.horizon-launcher play --arg=--benchmark --arg=standard writes a JSON report; horizon-launcher data benchmark <report> shows what would be sent and uploads it (playhorizon.dev/docs/performance).

Good first tasks

Each one is a small difference from vanilla, with an issue that says how to see it. Found one you like? Copy its /claim command and send it on Discord, so nobody starts the same work.

Each links its issue; the technical text says where in the code and in vanilla to start. /claim on Discord marks it as yours, /unclaim frees it.

  1. 01Benchmark your computerRun Horizon's built-in benchmark and share the report: every new computer makes the performance work more accurate. No coding needed.horizon-launcher play --arg=--benchmark --arg=standard writes a JSON report; horizon-launcher data benchmark <report> shows what would be sent and uploads it (playhorizon.dev/docs/performance). Results from three installs with the same hardware appear on the Benchmarks page. Example: #1711.

Ways to help

Take a task

Pick a good first task or an open issue. On Discord, /claim 1234 tells everyone you are on issue 1234, so nobody starts the same work; /unclaim frees it.

Open issues(opens in a new tab)

Bring your AI agent

On Discord, /agent connect gives your coding agent a personal token for Kira's MCP server: it reads the work board, claims tasks and posts its progress in your name.

Benchmark your computer

Run the built-in benchmark and share the report: every new machine makes the performance work more accurate. No coding needed.

How to

Report a bug

One bug per report: something that breaks, or doesn't play like vanilla. Fill this in and it opens as a ready issue on GitHub for you to check and send, with the steps in the order the maintainers need them.

Search the open bugs first

Issues are public, so leave out passwords and personal details. A screenshot or your log file helps: add it once the issue is open (where the log is). No GitHub account? Copy it for Discord and post it in #horizon-bugs, where Kira turns it into an issue.

The rules

  1. Vanilla is the specification. Wherever Minecraft 26.3 has the feature, Horizon does exactly what it does: read vanilla's code, then match it.
  2. Small pull requests, proven. One change each, under about 500 lines, with the block python3 tools/pr_ready.py prints: formatting, Clippy, tests and the harnesses your change can affect.
  3. Say who wrote it. If an AI agent wrote or posts it, the pull request says so, and commits keep its co-author line.
  4. Never commit Mojang's files. No game jars, assets, decompiled code or prepared resources, and nothing taken from other mods' code.

    Equals who decide by public 24-hour polls: rules, members, money and the project's direction.

  3. 🌌 Horizon Team

    Maintainers and core contributors: they review and merge pull requests, and moderate too.

    Nobody right now.

    Leads the moderators and can ban: the first person to reach for moderation questions.

  5. 🛡️ Mods

    Keep the Discord server friendly: they time out members and delete messages. Bans go through the council and the Chief of Mods.
