Good to Know

  • Zero config by default — Self-hosted mode uses SQLite, mediasoup, and local storage. No external services needed.
  • WebRTC — Requires UDP ports 40000-40100 open for voice/video.
  • Email — Required for email verification, MFA, and password resets. Resend has a free tier.
  • All features are free — Self-hosted instances have full access to everything.
  • Updates — DB migrations run automatically on startup.
  • Backups — Back up data/ and uploads/. That's your entire instance.
