Your data isn’t trapped on our servers. Colibri is built on the AT Protocol, the open network with 40M+ users, where you literally own your profile and messages.


Running more than just a group chat? Set up custom roles, manage permissions, and use built-in moderation to keep your community safe.


Future-proofed.
Running a private group chat? As soon as the AT protocol supports private data, we'll work on implementing it and giving you the option to create private communities.

Stuff you might ask about.
The AT Protocol (Authenticated Transfer Protocol) is an open, decentralized network originally created by the team behind Bluesky. It lets you truly own your identity and data - your account, posts, and social graph aren't locked into any single platform. With over 40 million users, it's a growing foundation for the next generation of social apps.
