Open-source alternatives to Postman
4 alternatives, ranked by a published maintenance score computed from live GitHub signals (fetched 2026-09-04). We flag unmaintained projects on both sides — including Postman itself when the data says so.
About Postman: Proprietary; the 2023 move forcing collections into cloud workspaces sent many users to offline-first alternatives. It is closed-source, so the same public maintenance signals do not exist for it — we score only the alternatives below.
