Bruno

What is Bruno?

Bruno is an open-source API client designed for developers who need to test and interact with APIs locally. It supports REST, GraphQL, gRPC, and WebSocket protocols, making it suitable for various API testing scenarios. As a Git-native tool, Bruno stores API requests and configurations as plain text files that can be version-controlled alongside project code, enabling seamless collaboration and tracking of changes. The tool positions itself as a local alternative to cloud-based API clients, with no external syncing requirements. This approach appeals to developers who prefer keeping their work and sensitive API credentials on their machines. Bruno emphasizes speed and developer-friendly workflows, featuring a straightforward interface that integrates with existing Git repositories. Being open-source and free, Bruno eliminates licensing costs and allows developers to review its source code. The project is maintained on GitHub, where community contributions are welcomed. Its Git-first design philosophy differentiates it from subscription-based competitors by treating API collections as code artifacts that benefit from version control practices. Bruno is primarily aimed at software developers, QA engineers, and teams that value local-first development approaches and want API testing integrated into their standard development workflows without relying on cloud services.
