Bruno

Bruno stores your API collections as plain text files in your Git repo. No cloud sync, no account, no telemetry — just `.bru` files alongside your code. For developers who believe API specs should be version-controlled like everything else, Bruno is the Postman replacement they've been wanting.

Postman is the incumbent with the deepest feature set but increasingly SaaS-dependent with cloud storage by default. Hoppscotch is browser-first and zero-install. Insomnia (Kong) has the best GraphQL experience. Bruno trades features for philosophy: offline-first, Git-native, no vendor lock-in.

Use Bruno if your team uses Git for everything and wants API collections to live in the repo, reviewed in PRs, and never stored on someone else's cloud.

The catch: Bruno is younger and less featured than Postman — no mock servers, limited team collaboration beyond Git workflows, and no CI-integrated test runner with the maturity of Newman (Postman's CLI). The `.bru` format is proprietary to Bruno, not an open standard. And for non-technical team members who just need to poke an API, Hoppscotch's browser UI is more accessible.
