Best API Clients for Git

Bruno is a developer-first, open-source API client that’s redefining what an API tool should be. Built from the ground up for speed, privacy, and simplicity, Bruno offers everything developers need to explore, test, and document APIs without the cloud lock-in, telemetry, or bloat that’s become standard elsewhere. Instead of chasing “platform” status, Bruno focuses on doing one thing exceptionally well: being a pure API client. It’s completely local... all your requests, environments, and collections stay on your machine. Nothing is uploaded or tracked. The result is a faster, safer, and more transparent workflow that developers actually enjoy using. Bruno is also Git-native, meaning collections live in plain text and can be versioned, diffed, and reviewed just like code. Branching, merging, and pull requests all just work — no proprietary formats or walled gardens. For teams that already use GitHub, GitLab, or Bitbucket, Bruno slots right in with zero friction. Under the hood, Bruno supports Postman and Swagger imports, test scripting in JavaScript, a powerful CLI, VS Code extension, and CI/CD integration for automated API testing. Since its launch in 2022, Bruno has seen explosive community growth: over 2.5 million downloads, 150,000+ daily users, and 37,000+ GitHub stars. Trusted by engineers at Microsoft, Capital One, GitHub, and FedEx, Bruno is proving that developer tools don’t need a cloud backend to scale , they just need to respect how developers actually work. In short: Bruno is what the API client should have been all along ... local, fast, Git-based, and open-source.
