Who it's for

Developers and teams building and testing APIs who want their API collections version-controlled and reviewable like code, rather than locked in a proprietary cloud account.

What you get

An open-source desktop API client for sending requests and organizing them into collections, similar to Postman or Insomnia. Collections are saved as plain-text .bru files in folders on disk instead of a database or cloud service. This means requests can be committed to Git, diffed, branched, and reviewed in pull requests alongside application code. It runs fully offline with no mandatory login or cloud sync.

How it works

You create collections of HTTP requests in the Bruno app, and each request is written to a .bru file in a folder structure on your filesystem. Because collections live as files in your project directory, you check them into your existing Git repo and use normal Git workflows (commit, branch, PR, merge) to share and version them with your team.
