Horizon
Horizon is Minecraft: Java Edition 26.3 rewritten in Rust
Horizon is an open-source reimplementation of Minecraft: Java Edition built from scratch in Rust, offering a native alternative to the original Java-based game. It recreates Minecraft's core gameplay mechanics, world generation, physics, mobs, redstone systems, and multiplayer functionality while maintaining compatibility with existing Minecraft worlds. Horizon includes a dedicated launcher that handles installation, updates, Microsoft account authentication, and game file preparation across Windows, macOS, and Linux. Players can customize their experience with graphics presets, extended render distances, controller support, resource packs, data packs, and native Rust mods. The platform also supports multiplayer servers, LAN connections, and AI agent interactions through a command-line interface and Model Context Protocol (MCP) server. Horizon uses differential testing against the original Minecraft implementation to verify gameplay accuracy. -

HuMidi
Play MIDI like a human in ROBLOX with automatic sustain pedals.
HuMidi is a universal piano auto player for ROBLOX. It plays even the most generic MIDI file with great depth, thanks to the humanization and automatic sustain pedal generation via Machine Learning models and algorithms. The pedals are generated with a thorough analysis of the MIDI data, adding more depth to your performance that no other MIDI players could! Personally have been tested in: - Visual Pianos - Starving Pianists - Digital Piano - Piano's Got Talent This tool is universal, as long as the piano in-game allows to be played on a keyboard. -

SteelMC
A Minecraft server in Rust focused on a strong foundation
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. -

BoilR
Synchronize games from other platforms into your Steam library
BoilR automatically adds (almost) all your games to your Steam library (including image art). It uses the Steam 3rd party shortcuts feature and does not require you to set up anything. The goal is that you do not have to leave your Steam library to launch games from other launchers/stores, so that you can find all the games that you have available. Optionally, you can set up BoilR to automatically download artwork from SteamGridDB. -

ggez
Rust library to create a Good Game Easily
ggez is a Rust library to create a Good Game Easily. More specifically, ggez is a lightweight cross-platform game framework for making 2D games with minimum friction. It aims to implement an API based on (a Rustified version of) the LÖVE game framework. This means it contains basic and portable 2D drawing, sound, resource loading, and event handling, but finer details and performance characteristics may be different than LÖVE. ggez is not meant to be everything to everyone, but rather a good base upon which to build. Thus it takes a fairly batteries-included approach without needing a million additions and plugins for everything imaginable, but also does not dictate higher-level functionality such as physics engine or entity component system. Instead, the goal is to allow you to use whichever libraries you want to provide these functions or build your own libraries atop ggez. -

Bevy
A refreshingly simple data-driven game engine built in Rust
A refreshingly simple data-driven game engine built in Rust. All engine and game logic uses Bevy ECS, a custom Entity Component System. Massively Parallel and Cache-Friendly. The fastest ECS according to some benchmarks. Components are Rust structs, Systems are Rust functions. Queries, Global Resources, Local Resources, Change Detection, Lock-Free Parallel Scheduler. Bevy is still in the very early stages of development. APIs can and will change (now is the time to make suggestions!). Important features are missing. Documentation is sparse. Please don't build any serious projects in Bevy unless you are prepared to be broken by API changes constantly. Bevy relies heavily on improvements in the Rust language and compiler. As a result, the Minimum Supported Rust Version (MSRV) is "the latest stable release" of Rust. Built directly on top of Bevy's ECS, Renderer, and Scene plugins. -

Accshift
One-click account switcher for Steam, Riot, Battle.net and Epic
Accshift switches game launcher accounts in one click, without signing out or retyping a password. It drives each launcher's own remember-me mechanism: the saved session is captured, one snapshot is kept per account on your machine, and the right one is restored on switch. No password is ever stored, and session data is encrypted at rest with DPAPI, the Keychain or the Secret Service. Launchers: Steam, Riot Games (Valorant, League of Legends), Battle.net (Overwatch 2, Diablo IV, WoW, Call of Duty), Epic Games (Fortnite, Rocket League), Ubisoft Connect, Roblox, and in testing GOG Galaxy, Jagex Launcher and Discord. Steam runs on Windows, macOS and Linux. Also: personas to switch several launchers at once, a streamer mode that blurs names and avatars while OBS or Streamlabs is running, folders, colour labels, search, a Ctrl+K command palette, a PIN lock, seven interface languages, and a scriptable CLI with accshift:// deep links.

hematite
A simple Minecraft written in Rust with the Piston game engine
Hematite is an experimental open-source project that attempts to reimplement aspects of the Minecraft game engine using the Rust programming language. Developed within the Piston ecosystem, the project serves primarily as a technical experiment exploring how Rust can be used to build complex game systems such as rendering, world simulation, and client architecture. Hematite aims to replicate core elements of Minecraft’s mechanics while leveraging Rust’s safety guarantees and modern performance capabilities. The project also explores the possibility of building alternative server implementations or game engines compatible with Minecraft-style gameplay. By rewriting core systems in Rust, the developers hope to create a more efficient and flexible architecture compared with the original Java-based implementation. The project includes components for rendering Minecraft-like worlds and experimenting with game engine features within the Piston graphics framework. -

Amethyst Game Engine
Data-oriented and data-driven game engine written in Rust
Data-driven game engine written in Rust. Amethyst uses a rigorous Entity Component System (ECS) architecture to organize game logic. This abstracts away some of the parallelism work, allowing easier exploitation of multi-threading in games. The ECS is rich in features and very efficient, as it never does any memory locking while remaining entirely thread-safe. Amethyst uses gfx-rs to render graphics with Vulkan or Metal. It is meant to be used for 2D and 3D, with various utilities for both types of games. It should be beginner friendly but also allow more advanced uses such as custom render passes and GLSL shaders. Thanks to the Rust programming language, Amethyst uses all CPU cores to run its internals and logic. A lot of optimizations have yet to be done, but the current status is already showing great potential. Amethyst is open source and free software. You can use, read, modify, distribute its source code under the permissive MIT and Apache 2.0 licenses. -
