The request names OpenAPI, which is a specification rather than a product, so the best fits are tools that generate code, docs or tests from an OpenAPI description. OpenAPI Generator 1 generates clients from OpenAPI documents, Redocly 6 turns an OpenAPI description into reference docs, an MCP server and tests, and Kubb 8 generates TypeScript types and clients from an API spec such as OpenAPI.
