Bruno

Overview of Bruno

Bruno is an innovative open-source API client designed specifically for developers who value performance, privacy, and version control integration. As a Git-friendly alternative to tools like Postman and Insomnia, Bruno operates entirely offline while providing robust API testing and development capabilities. The tool stores collections directly in your filesystem using Bru – a plain text markup language – making API requests easily versionable and collaborative through Git or any version control system of your choice.

Built with a developer-first philosophy, Bruno prioritizes essential API testing features without unnecessary platform bloat. Trusted by major organizations including GitHub, Capital One, Mercedes-Benz, Comcast, FedEx, and Tesco, this lightweight tool loads in seconds and consumes minimal memory. Bruno's commitment to open-source principles and extensibility makes it ideal for developers working in API Client environments and Version Control GUI workflows.

How to Use Bruno

Getting started with Bruno involves downloading the application, creating API collections in your local filesystem, and using the intuitive interface to build and test requests. Collections are stored as Bru files – human-readable plain text documents – that can be versioned using Git for seamless team collaboration. You can organize requests into folders, set environment variables, write test scripts, and execute API calls without requiring cloud synchronization or account creation, making it perfect for both individual developers and enterprise teams.
