Git-Native

Collections stored as plain text files in a folder, making version control seamless with Git or any VCS.

Developer-Friendly

​
Why Bruno?

​
Collections as Code

Bruno stores your API collections directly in a folder on your filesystem using a plain text markup language called Bru. This means:
  • Version control your API collections with Git
  • Collaborate with your team using pull requests
  • Review API changes in your standard code review workflow
  • No vendor lock-in - your data is always accessible

​
Privacy-First Design

Bruno is offline-only. There are no plans to add cloud-sync to Bruno, ever. We value your data privacy and believe it should stay on your device.
Read our long-term vision on data privacy and sustainability.

​
The Bru Language

Bruno uses a simple, readable format for storing API requests. Here’s an example: 
meta {
  name: echo json
  type: http
  seq: 2
}

post {
  url: {{host}}/api/echo/json
  body: json
  auth: none
}

headers {
  foo: bar
}

body:json {
  {
    "hello": "bruno"
  }
}

assert {
  res.status: eq 200
}

script:pre-request {
  bru.setVar("foo", "bar");
}

tests {
  test("should return json", function() {
    const data = res.getBody();
    expect(res.getBody()).to.eql({
      "hello": "bruno"
    });
  });
}
