What Corsair is
Corsair is an open-source integration layer designed specifically for AI products that need to connect to external applications. The problem it addresses is real: APIs change constantly, and authentication, routing, architecture, and error handling differ sharply between services, which makes wiring an AI product into Gmail, Slack, Notion, or Airtable a weeks-long engineering project. Corsair packages that work into a layer you can add in minutes, without maintaining complex infrastructure. It supports OAuth for standardized secure authorization, per-integration permission management where potentially destructive operations require explicit user approval with clear review links, MCP for monitoring and managing integrations, and webhooks for event-driven synchronization. Deployment is flexible: hosted in the cloud or self-hosted on your own servers, with self-hosting free. Pricing includes a free Hobby plan for small projects, Pro at $200 per month for production teams, and customized Enterprise plans, with a free trial that requires no credit card information.
What you can do with it
- Connect an AI chat or agent product to Gmail, GCal, Slack, Notion, Airtable, and similar services in minutes
- Enforce per-integration permission modes and require approval before destructive operations
- Trigger automated actions through webhooks when specific events occur
- Choose hosted or self-hosted deployment to match your security requirements
Who it is for
- AI product developers who want integrations without building and maintaining the plumbing
- Small project teams that fit within the free Hobby plan
- Enterprise-level teams handling complex data flows and needing customization
- Teams with strict security postures that prefer self-hosting their integration layer
What to watch out for
The jump from the free Hobby plan to the $200 monthly Pro plan is steep, so startups should forecast when they will cross that threshold and whether self-hosting makes more sense first. Self-hosting is free but shifts maintenance onto your team: security patching, upgrades, and uptime become your responsibility, which is a real cost even when no invoice arrives. Integration coverage depends on what Corsair supports, so verify that your required applications are available before committing. As with any middleware handling OAuth credentials and third-party permissions, review the permission modes carefully and apply least-privilege defaults. Finally, open-source projects can evolve quickly, and free tiers or licensing terms can change, so pin versions and monitor release notes in production.
