Plug AI into your own data & over 500 integrations

Type Safety

Fully type-safe queries and mutations.

Your IDE knows your input and output types. Catch errors at compile time, not runtime.

Zero Runtime Overhead

No performance penalty.

Code generation happens at build time. Your queries run at normal API speeds.

Schema-Aware

Automatic schema synchronization.

Change your database schema and Corsair updates affected queries automatically.

Real TypeScript Output

Generated code you can read and edit.

Corsair generates standard TypeScript API routes. View them, modify them, debug them like any other code.

Built for Coding Agents

CLI commands for Claude Code and Cursor.

Let your coding agent build queries through structured commands. No architectural compromises, no any types.

Plugin Ecosystem

Chain business logic with integrations.

Connect Slack, Stripe, Posthog, Resend, and more. Build complex workflows in plain English.
