Voice, video and text for your people.

A private place to hang out โ€” voice channels you can leave running in your pocket, screen share, camera, text chat and a music bot. No ads, no algorithms, no strangers.

Invite only โ€” create an account and an admin lets you in.

Everything you actually use

The parts of a chat app worth self-hosting, and none of the rest.

Queue tracks into a voice channel and fire off sounds, with independent volume for each.

It's not on the Play Store, so Android asks once for permission.

  2. Android will warn about unknown sources โ€” allow it for your browser.
  3. Install, open Gigachat and create an account.
  4. Ask an admin to approve you, then reopen the app. That's it.
