rizaladisaputra/open-api-tester — reverse-engineered prompt

Build me a browser based Modern API Studio for designing and testing OpenAPI specs without having to write YAML by hand.

I want a dark themed React app where I can create API projects, add endpoints visually, edit path params, query params, headers, request bodies and responses, then see a live Swagger preview beside it. It should also have a Postman style test panel where I can send HTTP requests, fill in path params and headers, edit JSON bodies with comments, and see status, timing, headers and response body.

Please include tools to paste raw JSON and infer a schema, generate mock JSON from schemas, and convert OpenAPI 3, Swagger 2, JSON and YAML. Save projects locally in the browser, and also support Supabase login, cloud saving, realtime collaboration, presence and basic roles like owner, editor and viewer.

Set up the monorepo, client app, shared types and utils, plus Supabase migrations and env examples so I can run it locally. Look up current docs online if needed.
