What This Is

Turn any website into a typed API. Scout captures network traffic, infers schemas, outputs OpenAPI. Worker replays endpoints directly. Heal re-scouts when paths break.

• MCP Server: https://unsurf-api.coey.dev/mcp
• Docs: https://unsurf.coey.dev
• Directory: https://unsurf.coey.dev/directory
• NPM: unsurf

Stack

• Effect — typed errors, DI, streams, retries
• Alchemy — infrastructure as TypeScript
• Drizzle — typed SQL (D1/SQLite)
• Cloudflare Workers — edge runtime
• Cloudflare Browser Rendering — headless Chrome
