HAR → OpenAPI Draft Generator
Draft OpenAPI path definitions and operations from real HAR traffic captures for downstream review and completion. Free by Graph Tools.
Use this free HAR to OpenAPI draft generator to bootstrap an API specification from real captured HTTP traffic. Upload a HAR file and get a draft OpenAPI document with path definitions, HTTP methods, inferred request parameters, and response shapes drawn from the actual traffic. The draft is a starting point for refinement and documentation rather than a complete spec. Useful for developers reverse-engineering undocumented APIs, API-first teams documenting existing services, and architects analyzing third-party integrations.
