Open Source Rust Minecraft Servers

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

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.

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.

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.
