Writing YAML for API docs? Stop. I built a free OpenAPI Builder that does it for you.

A developer built a free, browser-based OpenAPI Builder that replaces hand-writing YAML/JSON specs with a no-code form interface. It features live Swagger UI preview, auto-save, dual export (JSON/YAML), and import of existing specs, with output compatible with Swagger UI, Postman, ReDoc, and major API gateways. The tool targets creating new specs, prototyping APIs, and generating documentation without YAML expertise.
