Choose based on workflow
Postman is powerful for API collaboration, but some teams only need quick, stable mock endpoints with clear status codes and response bodies. A lightweight approach works well for landing pages, prototypes, frontend tickets, QA cases, and product demos.
The key is not the tool name; it is the quality of the mock contract. Document method, path, request body, response body, status code, and scenario. Keep mocks small enough to understand and stable enough to share.
