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

• About 50%–70% less memory than VRCX
• Background mode needs just tens of MB of memory, with all core features

• Smaller than a single avatar bundle — just over 10 MB to download, just

• Seamless migration — imports your VRCX database and settings

Only in VRCX-0

• Social AI — insights into your VRChat social life: who you play with

• Activity — look back on each visit on a timeline, with the world, who was

• Sidebar Mode — keep an eye on friends from a narrow sidebar; docks to the

• Desktop Overlay — a small desktop window of recent notifications for

• Pinned worlds — pin a world to the sidebar to see its public instances

• Keyboard shortcuts — common actions without the mouse; global hotkey on

• Lock — lock the interface with a code to protect your privacy
• Sharing — share links for world collections, worlds, avatars, and

• Game Log import — fill in the Game Log from VRChat's own logs for times

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

• Headless mode — run without a UI; see crates/headless

Install

Grab the file for your platform from the latest release:

| Platform | File | | --------------------- | ------------------------------------------- | | Windows | VRCX-0__windows_x86_64_setup.exe | | macOS (Apple Silicon) | VRCX-0__macos_aarch64.dmg | | macOS (Intel) | VRCX-0__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.
