VRCX 0

What is VRCX 0 about?

VRCX 0 is a cross‑platform desktop companion for VRChat that records where friends are, keeps a history of visited worlds and people, and offers AI‑driven social analytics. It replaces the original VRCX with a Rust/Tauri rewrite that consumes far less memory and runs in background mode with only a few megabytes.

How to use VRCX 0?

1. Download the appropriate installer from the latest release page – Windows .exe, macOS .dmg, or Linux .AppImage/.deb/.rpm.
2. Run the installer (macOS may require opening via System Settings → Privacy & Security → Open Anyway on the first launch).
3. On first start, VRCX 0 will automatically import your existing VRCX database and settings. No manual migration is needed.
4. Configure AI integration in Settings → AI by providing the endpoint of the AI service you already use.
5. For developers, clone the repo, run npm install, then start the development version with npm run tauri:dev. Build a release with npm run tauri:build -- --no-sign --no-bundle.

Key features of VRCX 0

• Smooth handling of years‑long history – even on low‑end PCs.
• Memory footprint 50‑70 % lower than the original VRCX.
• Background mode runs with only tens of megabytes.
• Social AI – insights such as top play‑partners, drift detection, and online‑time predictions.
• Activity timeline – view worlds, participants, and screenshots per visit.
• Sidebar & desktop overlay – quick glance at friends without leaving the game.
• Pinned worlds, keyboard shortcuts, privacy lock, link sharing, and game‑log import.
• MCP server & Integration API – expose real‑time social data to external tools.
• Experimental headless mode and self‑hosted recorder for always‑on logging.
• Cross‑platform – Windows, macOS (Apple Silicon & Intel), Linux.

Use cases of VRCX 0

• Social analytics for streamers or community managers who want AI‑generated reports on engagement patterns.
• Power users who keep a personal archive of worlds, friends, and screenshots.
• Developers building third‑party bots or dashboards that consume VRChat data via the MCP server.
• Low‑spec PC owners needing a lightweight companion that can run in the background.
• Privacy‑conscious users who can lock the UI and keep data local.

FAQ from the VRCX 0

• Q: Do I lose any data when switching from VRCX to VRCX 0? A: No. VRCX 0 imports the existing VRCX database without modifying it, allowing you to revert at any time.
• Q: Can I run VRCX 0 without the UI? A: Yes. Use the headless mode located in crates/headless for background operation only.
• Q: How does the AI assistant work? A: Connect any compatible AI service (e.g., OpenAI, Anthropic) in the settings; VRCX 0 sends local social data to the service and displays insights.
• Q: Is hardware acceleration required? A: It is optional and experimental. Enable it in Settings → System → Hardware acceleration if the interface renders incorrectly.
• Q: What platforms are officially supported? A: Windows (x86_64), macOS (Apple Silicon & Intel), and major Linux distributions via AppImage, DEB, or RPM.
• Q: Where can I get help? A: Join the Discord community, file issues on GitHub, or read the developer blog for updates.

A desktop companion for VRChat: see where your friends are, keep a history of the people you've met and the worlds you've visited, manage your favorites, and more.

VRCX-0 is a ground-up rewrite of VRCX by one of its former maintainers. Rebuilt in Rust, it's faster and lighter, and years of history stay smooth.

Highlights

• Years of history stay smooth — data that makes VRCX sluggish runs smoothly in VRCX-0, even on low-end PCs and home servers
• About 50%–70% less memory than VRCX
• Background mode needs just tens of MB of memory, with all core features still running
• Smaller than a single avatar bundle — just over 10 MB to download, just over 30 MB installed; less than a tenth the size of VRCX
• Seamless migration — imports your VRCX database and settings automatically; VRCX's own database is never modified, so you can switch back at any time

Only in VRCX-0

• Social AI — insights into your VRChat social life: who you play with most, who you're drifting away from, when friends are most likely online; just connect the AI service you already use
• Activity — look back on each visit on a timeline, with the world, who was there, and your screenshots; see the non-friends you keep running into
• Sidebar Mode — keep an eye on friends from a narrow sidebar; docks to the screen edge and auto-hides on Windows and macOS
• Desktop Overlay — a small desktop window of recent notifications for desktop-mode players, in place of system notifications; Windows only
• Pinned worlds — pin a world to the sidebar to see its public instances and which friends are there, and join from right there
• Keyboard shortcuts — common actions without the mouse; global hotkey on Windows
• Lock — lock the interface with a code to protect your privacy
• Sharing — share links for world collections, worlds, avatars, and instances
• Game Log import — fill in the Game Log from VRChat's own logs for times VRCX-0 wasn't running

For advanced users

• MCP server — let external AI tools use your local social data directly
• Integration API — real-time in-game data for third-party apps
• Self-hosted Recorder (experimental) — runs on your own server and keeps your Feed recording while VRCX-0 is closed; the gap fills in the next time you open it
• Headless mode — run without a UI; see crates/headless

Everything else VRCX does, VRCX-0 does too.

Install

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

On macOS, if the first launch is blocked, open System Settings → Privacy & Security and click Open Anyway.

Linux

Hardware acceleration for the app interface is off by default. Turn it on under Settings → System → Hardware acceleration (experimental); if the interface doesn't display properly, VRCX-0 turns it back off automatically. Setting WEBKIT_DISABLE_DMABUF_RENDERER yourself hides this option.
