Our take: Use Corsair if you are a TypeScript developer who wants one typed syntax for 200+ integrations with managed OAuth, webhooks and rate limits, while keeping credentials in your own database.

Main limitation: The free Hobby tier is capped at 50 connections, 100k webhook events and 3 team members, and Pro jumps to $200 per month.

Who Corsair fits

Use Corsair if you are a TypeScript developer who wants one typed syntax for 200+ integrations with managed OAuth, webhooks and rate limits, while keeping credentials in your own database. Based on the vendor's documentation, not on a hands-on test.

Best for: Developers building AI agents that need tool access

Also a good fit for

  • SaaS teams shipping many third-party integrations
  • Multi-tenant B2B products

Consider another tool if hobby tier capped at 50 connections, 100k webhook events and 3 team members

Or if

  • Pro plan costs $200/mo
  • Developer-oriented: requires writing TypeScript or SDK code

What is Corsair, and how does it work?

Corsair is an open-source integration layer for apps and AI agents. Developers install plugins for services such as GitHub, Slack, Gmail or Notion and call every integration through the same typed syntax, while Corsair handles OAuth, token refresh, webhooks and rate limits. It runs inside your own app, with credentials encrypted in your own database; the hosted Hub serves connect pages and OAuth callbacks. Corsair Cloud is a hosted runtime where each tool call is an HTTP request authenticated with a project API key, with clients for TypeScript, Python, Go, Swift and curl. The library is Apache 2.0 licensed and the pricing table lists a free Hobby tier, a Pro tier and custom Enterprise plans.
