Integration Layer for AI Agents
What Corsair is: Corsair gives you (or your agent) safe access to hundreds of integrations. It natively handles all integration plumbing. The only code you write is the code that's specific to your use case. Your data stays yours. Why we wrote it: Integrations make products capable. Integrations are also frustrating to write. If you look at any codebase with integrations, 95% of the code is identical. It's all just basic plumbing. The part of the integration that is unique to a codebase and actually adds value is probably just a few lines. We shouldn't waste time writing and maintaining the 95% for a few lines. The developer community has just accepted that we do. Corsair handles the 95% so you don't have to. It's really hard to get wrong.
Corsair is an open source integration layer designed for AI agents, enabling secure, multi-tenant integrations with OAuth, permissions, webhooks, and hosted or self-hosted execution. It aims to remove infrastructure maintenance for integrations and reduce vendor lock-in by providing an open-source platform you can self-host or run in the cloud.
Corsair provides an SDK and hosting options to connect to various apps (e.g., Gmail, Slack, Notion, Google Calendar) via a standardized credential model and webhook pattern. It offers multi-tenancy, per-integration permission modes, explicit approval for destructive actions, and the ability to run the full SDK on your own infrastructure or use hosted/mcp-based access. The platform supports self-hosting for zero per-seat pricing and allows adding new integrations through open source contributions (PRs) or forks, with hosted deployment available and API-driven provisioning of tenants and plugins.
Who it’s for: Teams building AI-powered products or agents that require multiple third-party integrations and value control over infrastructure, security, and customization.
