Bruno Review

What is Bruno?

Bruno is an open-source API client built for developers who want a fast, privacy-respecting alternative to cloud-based API platforms.

Its defining characteristic is that it is Git-native and local-first: API collections are stored as plain-text files using its open Bru markup language directly inside your repository, so requests can be version-controlled, branched and reviewed alongside application code with no cloud sync and no mandatory account.

Bruno keeps all data on your machine, which appeals to security-conscious teams and organizations with strict data-handling requirements.

It supports building and sending REST, GraphQL and gRPC requests, scripting and assertions for testing, environments and variables, and a collection runner for automated test flows, and it can run in CI through its command-line runner.

Because collections live in Git, teams reuse existing repository permissions and access controls rather than a separate platform. Use cases include everyday API testing during development, keeping API definitions in sync with code, and meeting privacy or compliance needs that rule out cloud tools.

Pros include true data locality and privacy, Git-friendly versioning of API tests, and a free open-source core trusted by large organizations. Cons are that it lacks the cloud collaboration and monitoring features of platforms like Postman, and built-in AI assistance is limited compared to AI-first competitors.

Bruno offers a free open-source app with paid options for advanced and enterprise features. Pricing changes often, so check the official site for current plans.
