Claire developer docs

Architecture overview

How Claire connects mobile, desktop, the API, Matrix, and plugins.

Architecture overview

Claire is a unified messenger. The mobile and desktop clients talk to a Bun API. In PLATFORM_MODE=matrix, the API talks to Synapse and mautrix bridges. Messages are stored in Postgres through Supabase.

Mock mode bypasses live bridges so contributors can work without messaging accounts.

Durable details live in:

Repository setup

Clone Claire and start mock mode without third-party accounts.

Mobile development

Work on the Expo iOS, Android, and mobile web client.
