The transparent, feature-rich desktop bridge for VRChat remote control
Seamlessly bridge VRChat OSC with the ARC, privacy-first, open-source, and fully transparent.
Features • Installation • Configuration • Gallery • Documentation
ARC-OSC Client is a standalone Electron desktop application that serves as the bridge between VRChat and the ARC-OSC server. It enables real-time avatar parameter synchronization, heart rate streaming and VRChat API integration
🔒 Transparency First: This client's source code is public to ensure users know exactly what they're running. Privacy matters.
Connect seamlessly to the ARC-OSC server infrastructure. Authenticate with your credentials and enjoy real-time bidirectional synchronization of avatar parameters between VRChat and the web dashboard.
- Secure authentication with username/password
- Automatic reconnection handling
- Support for Live, Beta, and custom server URLs
- Real-time parameter sync
