Bruno
Bruno is an open-source, Git-native API client that stores collections as plain-text files in a repository, enabling version control, code review, and local execution without cloud dependency. It supports REST, GraphQL, gRPC, and WebSocket protocols across desktop, CLI, and VS Code surfaces, all built on the OpenCollection YAML standard. The tool is designed for developers and DevOps teams seeking a secure, offline-capable alternative to cloud-locked API platforms.

Problem
Traditional API clients are often cloud-based platforms that lock users into proprietary ecosystems, requiring data to be stored on external servers. This creates security concerns, limits offline access, and complicates collaboration and version control for development teams. Developers are forced to rely on bloated tools that do not integrate well with their existing Git-based workflows.
Solution
Bruno provides a Git-native API client that stores collections as plain-text files directly in a repository, making them human-readable, diff-friendly, and fully version-controlled. The tool works seamlessly with Git, IDEs, terminals, and AI agents, allowing developers to manage API collections as code. Bruno is open-source and locally executed, ensuring that data never leaves the user's machine, and it inherits existing enterprise security policies such as device management, repo permissions, and network controls. It also supports CLI execution for CI/CD integration, mock servers, and API documentation generation, all built on the open OpenCollection standard.
Target Audience
Primary users are software developers, API engineers, and DevOps teams who need a secure, version-controlled, and locally executed API client that integrates with their existing Git and CI/CD workflows.
