- Mojang did not rewrite Minecraft in Rust and did not announce anything like that. Java Edition is still written in Java, Bedrock is still written in C++.
- The noise around “minecraft growing” is due to Horizon:This is an unofficial fan project on GitHub, which appeared on October 3, 2026, and writes that Java Edition 26.3 was rewritten from scratch in the programming language Rust.
- “100% parity with vanilla” - assessment of the project itselfnot an independent audit. The authors are saying that 100% is a fraction of what their tests compare, not evidence that nothing else is different.
- Regular Java mods in Horizon do not work, and you can only play it with your purchased copy of Minecraft.
- There are other projects on Rust: server FerrumC, library Rimecraft, mod Oxidizium. None of them replace the game.
- Rust in this story is a programming language. The game Rust from the studio Facepunch has nothing to do with it.
Everything below is based on the README of projects on GitHub and Modrinth and on the minecraft.net website, verified on October 30, 2026. Links are at the end of the article.
