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

Compared with VRCX

Everything else VRCX does, VRCX-0 does too.

Install

Grab the file for your platform from the latest release:

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.
