Open Source Rust Minecraft Servers

A minimalistic, lightweight Minecraft server written in Rust, designed to handle simple multiplayer tasks.

SteelMC is an independent Minecraft Java Edition server implementation written in Rust. It aims to reproduce vanilla behavior while using modern multicore processors more efficiently. Gameplay updates remain synchronous, while chunk generation, lighting, packet processing, and chunk transmission can run outside the main server tick. Players can join persistent multiplayer worlds, move, interact with blocks, manage inventories, use commands, chat, and return to previously saved areas. Its networking layer supports Java Edition authentication, encryption, compression, and protocol communication. World generation is currently its most complete system and is tested against reproducible vanilla chunks for block-level parity. SteelMC remains in pre-alpha, with incomplete survival mechanics, limited entity behavior, no plugin system, and no compatibility with Bukkit, Paper, Fabric, Forge, or NeoForge extensions.

A Minecraft 1.20.4 creative server built for Redstone. Each 256x256 plot runs on a separate thread, allowing for less lag, more concurrency, and many awesome extra features. MCHPRS is very different from traditional servers. Because this server is tailored to the use of computation redstone, many things that are a part of Vanilla Minecraft servers don't exist here. That being said, MCHPRS comes with many of its own unique features.

FerrumC is a re-implementation of a server for the game Minecraft (version 1.21.8) built from scratch in Rust, designed to offer significantly improved performance and memory efficiency compared to vanilla server implementations. By using Rust’s concurrency and safety guarantees, FerrumC runs fully multithreaded, allowing it to utilize all available CPU cores — which helps deliver smoother, low-latency, high-throughput multiplayer experiences. The project aims both at providing a fast, lean server for typical use (friends or small communities) and offering a foundation that could support large-scale servers, mod/plugin systems, and custom server configurations. FerrumC supports importing existing Minecraft worlds, making it easy for users to migrate from standard servers without losing progress. Its networking, world encoding (chunks, NBT, Anvil format), and entity systems are custom-built with efficiency in mind, which results in fast world loading, minimal I/O lag.

Rust framework for building Minecraft: Java Edition servers. Built on top of Bevy ECS, Valence is an effort to create a Minecraft-compatible server completely from scratch in Rust. You can think of Valence as a game engine for Minecraft servers. It doesn't do much by default, but by writing game logic yourself and leveraging Bevy's powerful plugin system, you can make almost anything. Opinionated features like dynamic scripting, dedicated executables, and vanilla game mechanics are all expected to be built as optional plugins. This level of modularity is desirable for those looking to build highly custom experiences in Minecraft such as minigame servers.
