Stop writing README files for your API. Use a living, breathing specification that stays updated with your code.
1The Contract First Approach
Instead of building first, you can define the OpenAPI spec first. This 'contract' allows frontend and backend teams to work in parallel, mocking the API before a single line of backend logic is written.
2Interactive Testing
Swagger UI isn't just for reading. It has a 'Try it out' button for every endpoint, allowing you to send real requests (with headers and bodies) and see real responses without opening Postman.
3Standardization
Following the OpenAPI spec means your documentation is compatible with thousands of other tools—from automated security scanners to automated testing suites.
