We're UnionCrax Team, a small group of developers building open-source game tools, launchers, and utilities. Our focus is on:
- Steam API tooling - bypass and compatibility layers for game preservation
- Game launchers - fast, modern apps for managing and launching games
- Controller APIs - input handling for games without native Steam Input
- Workshop tools - mod and addon management made simple
|
Custom Steam API
|
The original Steam spoofer, makes Steam think you're playing Spacewar (App ID 480), enabling online multiplayer via the Spacewar lobby system. The foundation that started it all.
|
|
A fast Electron desktop app for browsing, downloading, and launching games from the UC library. Features pause/resume downloads, auto-updates, game library management, and sync with the UC website.
|
Native launcher companion for UnionCrax.Direct. Handles game process launching and management on the C++ side for performance-critical operations.
|
|
Workshop mod & addon manager for games you "got". Browse, download, and install mods straight to any game's mod folder.
|
Controller input API modeled after Steam Input - captures controller inputs and exposes them via XInput/DInput/SDL2. Designed as a backend for frontends or games that don't want Steam.
|
Minimal CLI launcher for ShadPS4 written in C and compiled with TCC. Lightweight wrapper for headless/script-driven emulator usage.
|
|
HLA NoVR launcher without Steam launch requirements — launches
