OpenAPI Studio — route code in, an OpenAPI 3.1 spec out

Paste your API route code (any framework), an existing OpenAPI/Swagger document, or plain design notes — and get a complete OpenAPI 3.1 specification plus a senior API engineer's contract review: a ship-readiness posture, the endpoint inventory, prioritized findings with corrected spec fragments, quick wins and focus areas. A free instant prescan extracts your routes and flags contract smells before you run anything. Export the spec as openapi.yaml or openapi.json. Derived from the @wshobson/openapi-spec-generation skill.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
