OPEN BY DESIGN.

Bluesky is actively building permissioned data: a protocol-level way to keep some data private within a space instead of broadcasting it to the whole network. Until that ships, Colibri stays in limited early access: we won't promise private spaces we can't yet secure. The moment permissioned data launches, Colibri will too.

YOU OWN YOUR DATA.

Your data isn’t trapped on our servers, it's stored within the personal data server that hosts your ATmosphere profile. You can check our FAQ page for more information.

A MODERN, SIMPLE, AND FAMILIAR UI.

QUESTIONS? WE’VE GOT ANSWERS.

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.
