Colibri, a chat and calling app based on the same AT Protocol as Bluesky, has been released, allowing users to save their chat history on their device.

The social networking service Bluesky is developed based on an open social protocol called '

AT Protocol ,' which allows users to reuse their data across AT Protocol-based apps. ' Colibri ' is an AT Protocol-based communication app that enables chat, voice calls, and video calls.

Chats where you truly own your data.

AT Protocol is said to be inspired by Discord and Slack, resulting in a UI that resembles existing communication apps.

Voice and video calls are also available. The screen during a voice call looks like this:

The profile screen looks like this.

You can log in to Colibri using your Bluesky account. Colibri's personal data is stored in a PDS (Personal Data Server), and for typical Bluesky users, the data is stored in a user-specific PDS hosted by the Bluesky operations team. If you are self-hosting your PDS, you can manage your data on your own PDS.

Colibri is developed as open source, and its source code is available at the following link.
