Open Source Rust Game Servers

SteelMC is a Minecraft server written in Rust. Steel first achieved block-for-block terrain parity on May 20, 2026. The current parity suite covers 7,500 randomly selected chunks: 2,500 in each dimension. Steel is still pre-alpha, but you can already connect to it, explore persistent generated worlds, interact with blocks and inventories, and begin building on what is already there. Most of those nine months have gone into systems that are almost invisible when you join the server. As they mature, new gameplay features require less supporting infrastructure, and more of the work should begin showing up in the game.
