What it is
Horizon is a Rust reimplementation of Minecraft: Java Edition 26.3, written from scratch. The description says it has been checked against the vanilla game using 281 differential harnesses, and that you obtain it through the Horizon launcher. Topics include wgpu, Vulkan, voxel and differential-testing, and the license is listed as MIT.
Important notice
The README preview states this is not an official Minecraft product, and that neither Mojang nor Microsoft has endorsed or is connected to it. Horizon ships none of the original game's code, assets or data, so players must already own a lawful copy of the Java Edition 26.3 game.
Capabilities described
- Singleplayer with vanilla-style world generation, mobs, villagers, raids, redstone, all commands, the HUD and the recipe book. - Saves in vanilla's format, with worlds from 1.8 through 26.2 upgraded the way vanilla does it. - Horizon's own extras, including new menus (vanilla's remain one setting away), graphics presets and distant terrain.
