VRCX-0 is a ground-up rewrite of VRCX built on Tauri + React, replacing the original CefSharp + Vue stack. It is developed by one of VRCX's former maintainers.
VRCX-0 is designed for everyday use: dramatically lower resource usage, a smaller install, and an active development roadmap. As the upstream VRCX project has shifted toward maintenance, VRCX-0 is where new features are being built.
- 50%–70% lower memory usage than VRCX
- Just over 10 MB to download, just over 30 MB on disk — over 10× smaller than VRCX
- Background mode — a step beyond minimizing to tray: opt in to drop memory to just tens of MB while all core features keep running normally
- Social Automation — auto-switch your status and bio based on time of day, instance type, or who you're with; auto-accept invite requests; restores your previous state when rules expire
- Lightweight VR wrist overlay with minimal performance impact; supports both OpenVR (SteamVR) and OpenXR (Linux / WiVRn / Monado)
- Community Themes — browse and install themes from a catalog, set a custom background image, and layer your own CSS on top
- Three notification channels — desktop notifications, text-to-speech, and VR overlay alerts, each independently configured per event type
- Full keyboard navigation
- Headless mode for advanced setups — see
crates/headless - Actively developed with new features on its own roadmap
On first launch, VRCX-0 can automatically import your existing VRCX database and settings. Your original data is never modified — existing users can pick up right where they left off without any manual setup.
