Horizon

Features

• A new game program, not a mod. Horizon is written from scratch in Rust. It reads the same worlds, plays by the same rules and generates the same terrain as the Java game.
• Checked against vanilla. 281 automated tests ("harnesses") feed the same inputs to Horizon and to the real game, then compare the results. Today every subsystem matches in every harness that compares it. That is 100% of what the harnesses compare, which is not proof that nothing else differs. The status table lists what is covered.
• Light and fast. It starts quickly, uses little memory and draws efficiently. See Performance for what is measured and what is not.
• A few things vanilla doesn't have. Its own settings, added to vanilla's menus the way mods add theirs, graphics presets, distant terrain, controller support, optional extras such as dynamic lights, official mods such as zoom and a minimap, an invite code to play your world with friends, and a server you can run without Java.
• Not Minecraft itself. Horizon contains no Minecraft code, assets or data, and it never downloads them. You need your own legally obtained copy of Minecraft: Java Edition 26.3. Horizon builds its game files from that copy, on your computer.
• Not a place where Java mods run. Forge, NeoForge, Fabric and Quilt mod jars do not work in Horizon, and neither do Mixins. Horizon has its own mod system, and the launcher can port some Java mods' content. See Mods and data packs and Modpacks.
• Not for other versions. Horizon plays Java Edition 26.3. Worlds from older versions (1.8 to 26.2) are upgraded the way vanilla upgrades them.
• Not an official Minecraft product. It is not approved by or associated with Mojang or Microsoft.
• Not able to sign in to a Microsoft account yet. Until it can, Horizon cannot join servers that check accounts. See Multiplayer.
