Routebase vs Postman Comments
Positive comment by dennyR · Jul 30, 2026
In Postman the collection is the real artifact and the OpenAPI spec rots behind it. Routebase flips it: the spec is the artifact, and docs, mocks, contract tests and monitors all generate from it. Change the contract once and everything downstream follows — no repeating yourself in four tools.
