VRCX-0 is a ground-up rewrite of VRCX by one of its former maintainers, rebuilt on a native Rust core (Tauri + React) with significantly improved performance: years of accumulated history stay smooth, and both memory usage and install size are far below the original.
On first launch it automatically imports your existing VRCX data and settings. The original data is never modified — you can switch back at any time.
The upstream VRCX project has shifted toward maintenance; VRCX-0 is where new features are being built.
Grab the file for your platform from the latest release:
| Platform | File |
|---|---|
| Windows | VRCX-0_<version>_windows_x86_64_setup.exe |
| macOS (Apple Silicon) | VRCX-0_<version>_macos_aarch64.dmg |
| macOS (Intel) | VRCX-0_<version>_macos_x86_64.dmg |
| Linux | .AppImage, .deb, or .rpm |
You only need to do this once — VRCX-0 updates itself from then on.
- Years of history won't slow it down — data that makes VRCX visibly sluggish stays smooth in VRCX-0; it runs fine even on a potato PC or a home server
- About 50%–70% less memory than VRCX in normal use
- Background mode brings it down to just tens of MB while all core features keep running
- Smaller than a single avatar bundle — just over 10 MB to download, just over 30 MB on disk; over 10× smaller than VRCX
- Zero-friction migration — your VRCX database and settings import automatically; the original data is never modified
Beyond that:
- Social AI — a built-in assistant that helps you make sense of your VRChat life: ask who you play with most, who you're drifting away from, or the best time to catch friends online. Connect your own AI service to get started
- MCP server — let external AI tools access your local social data directly, far more flexible than the built-in assistant; recommended for advanced users
- Per-account local history — game logs and account-specific history are stored separately, so activity no longer gets mixed into a single timeline when you use multiple accounts
- Backup & restore — one-click compressed backup with scheduled automatic backups and multiple versions; restore from any backup at any time
- Shareable world collections — turn your favorite worlds into a shareable page others can browse, open, or import; also supports share links for individual worlds and avatars
- 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 — supports OpenVR (SteamVR) and OpenXR on Linux (tested with WiVRn)
- Community Themes — browse and install themes from a catalog, set a custom background image, and layer your own CSS on top
- Notifications — desktop, text-to-speech, VR overlay, and webhooks — four channels independently configured per event type; webhooks use a Discord-compatible format
- Full keyboard navigation
- Integration API for third-party apps — currently room data, expanding over time
- Headless mode for advanced setups — see
