How to use OpenAPI Generator

Enter your API endpoints, methods, and parameters, and the tool assembles an OpenAPI 3.0 YAML skeleton you can extend into full API documentation.

Frequently asked questions

Can I import this into Swagger or Postman?

Yes. The output is standard OpenAPI 3.0 YAML, which Swagger UI, Postman, and most API documentation and testing tools import directly.

Can I use this file directly on my live site?

Yes, as a starting point — double-check paths, URLs, and directives against your actual domain before deploying.

Does this tool call any external API to generate the file?

No. Everything is built client-side in your browser from the values you enter.
