The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
Postman
Postman — My default recommendation for teams that need the broadest all-in-one API workspace, because Collections, scripted tests, scheduled runs, monitoring, performance testing, collaboration, and CI/CD execution via Postman CLI are unusually complete in one product.
ChatGPT
Swagger UI / ReadyAPI
Swagger UI / ReadyAPI: Ideal for developers following a design-first approach, as it seamlessly integrates with OpenAPI specifications to generate and execute tests.
Gemini
Where the models split.
Across the 1 category Postman and Swagger UI / ReadyAPI both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks Postman ahead at least as often as not, with Gemini the most lopsided.
