How is this different from existing integration products?

Corsair is open source, so developers can add any integration themselves instead of waiting for the product team. Additionally, credentials are never stored in Corsair's database; they remain in the customer's own database, so a security breach at Corsair would not expose customer credentials.

Why not just code integrations manually?

While manual integration can reach 80% functionality quickly, the remaining 20% including token refresh, webhook verification, API deprecations, rate limiting, and multi-tenant credential isolation becomes a significant maintenance burden that distracts from core product development.

Does the AI agent see API keys?

No. Corsair resolves credentials internally at call time. Agents only see method names and results.

How does caching work?

Data flowing through Corsair is stored and kept fresh via webhooks and polling, partitioned per tenant. This allows repeated queries to hit the database instead of making repeated requests to the third-party API, which helps with rate limit concerns.

Can I use this without an AI agent?

Yes. Corsair can be called like any typed library to add features such as sync buttons, create actions, or post triggers without requiring an AI agent.

Overview

Screenshot of the Corsair homepage — What corsair.dev looks like

Corsair is an open source integration layer designed for AI agents and products. It enables developers to add secure, multi-tenant integrations with third-party applications without maintaining complex infrastructure. The platform handles OAuth authentication, permission management, webhooks, and supports both hosted and self-hosted execution.

The SDK addresses common integration challenges including API authentication flows, token refresh, webhook signature verification, and multi-tenant credential isolation. Developers can connect to numerous apps including Gmail, Slack, Notion, Airtable, Linear, GitHub, and others. Credentials are never exposed to agents; instead, Corsair resolves them internally at call time.

Corsair is fully open source, allowing developers to add custom integrations or fork the repository. The platform offers both a free self-hosted option and cloud-hosted tiers with managed authentication and permissions pages. All credentials and data remain in the customer's own database when using the hosted version.
