Bruno for Mac

Bruno — macOS API explorer (open-source)

Bruno is a free, open-source integrated environment tailored for exploring and testing APIs on macOS. It provides a streamlined interface that helps developers and testers compose requests, examine responses, and run API-related workflows without leaving the application.

Interface and typical workflow

• Compose HTTP requests quickly using a clean, focused editor.
• Examine and debug responses with built-in inspectors and formatted output.
• Save and group requests so common calls can be reused across projects.
• Run sequences of requests and inspect headers, bodies, and status codes directly in the app.

Authentication and protocol support

• Support for multiple authentication schemes so Bruno works with a wide range of APIs.
• Compatibility with common HTTP methods and content types for flexible testing.
• Customizable request headers and payloads to match API specifications.

Project organization and productivity

• Store and organize request collections, making it easier to switch between tasks.
• Tag or group requests for rapid access during development and QA cycles.
• Export or import collections to share setups with teammates or move between machines.

Community, licensing, and extensibility

• Open-source licensing encourages contributions and lets teams audit the codebase.
• Community-driven enhancements and plugins help expand functionality over time.
• Regular updates from contributors keep the tool evolving with new features and bug fixes.

Free alternatives worth considering

• Postman — a widely used, feature-rich API client with collaboration tools.
• Insomnia — a simpler, elegant HTTP client focused on requests and environments.
• HTTPie — a command-line oriented option for developers who prefer terminal-based interaction.
