Bruno

Bruno is an "offline-first API client" that revolutionizes how developers test and manage APIs. Instead of forcing you to create accounts or store data in the cloud, Bruno saves everything directly on your device using a simple text format called "Bru."

This approach means your API collections, tests, and sensitive data never leave your computer unless you choose to share them. Bruno supports all major API types including REST, GraphQL, and gRPC, making it versatile for any project.

The tool integrates seamlessly with Git and other version control systems, allowing teams to collaborate on API collections just like they do with code. Bruno also includes JavaScript-based testing, environment management, and command-line support for automation and continuous integration workflows.

Bruno is designed to be straightforward for both beginners and experienced developers. You can download it for free and start testing APIs immediately without creating any accounts.

Steps to get started with Bruno:

• Download Bruno from the official website for your operating system (Windows, Mac, or Linux).

• Create a new collection by clicking "Create Collection" and choosing a folder location.

• Add your first API request by specifying the method (GET, POST, etc.) and URL.

• Configure headers, parameters, and request body as needed for your API.

• Run the request and view the response with syntax highlighting and formatting.

• Add JavaScript tests in the "Tests" tab to validate responses automatically.

• Use environment variables to manage different configurations (development, staging, production).

Tips for better results:

Bruno works best when you organize your API collections alongside your project code in Git repositories. This keeps everything in sync and makes it easy for team members to access the latest API examples. For complex testing scenarios, use Bruno's JavaScript testing capabilities to create automated validation scripts that run with your CI/CD pipelines.
