Corsair is an open source product that lets an app integrate with anything. Hundreds of integrations are available — Gmail, Slack, Google Calendar, Microsoft Teams, GitHub, Linear, and more. For the full list, see api.corsair.dev/md/integrations.
Setting up with a coding agent? Use Agent setup — clarify intent, provision via the SDK, ask when instance/tenant/plugin choice is unclear.

​
Two ways to use Corsair

You can use Corsair in chat or a UI (or both). Each works in single-tenant or multi-tenant setups.

npm install @corsair-dev/app
Get a developer API key from the Corsair dashboard, then:
