Bruno review

The git-first choice that keeps API tests in your repo, not a vendor cloud.

Verdict

Bruno is the best open-source API testing tool because it stores every request and assertion as a plain Bru file in your repository, so tests version and review exactly like code and run in CI through the bru CLI.

What customers praise

Working fully offline with no account removes the compliance headache of cloud collections, and plain-text Bru files produce clean, reviewable diffs in pull requests.

What customers criticise

Protocol coverage trails Postman, with gRPC and event-stream support still maturing, and load testing is not a first-class feature.

Best for

Engineering teams that want their API tests stored as plain text files in git, run offline with no login, and reviewed in normal pull requests.
