Bruno: The Git-native API client

Bruno is an open-source API client built around keeping request collections as human-readable files alongside application code, rather than storing them in a cloud platform. Its collections use the OpenCollection standard and are designed to be readable, easy to diff, and manageable through ordinary Git workflows: teams can branch, review, merge, and share them with the same tools they use for code. The product is presented as usable across a desktop app, IDEs, the terminal, and AI agents, with features for organizing and running requests, managing variables and environments, and importing existing Postman collections.

A central argument is that API tooling should fit developers’ existing workflows without requiring accounts, cloud sync, or a separate collaboration platform. Bruno says requests and data stay on the user’s device, with sharing controlled through Git; it also highlights a SOC 2 Type II audit and enterprise support for SSO/SAML, SCIM, and secret managers such as Vault, Azure Key Vault, and AWS. Its security model is framed as inheriting existing device, repository, network, and data-residency controls rather than adding a new cloud tenant. User testimonials emphasize the lightweight local-first approach, simpler version control, offline access, team adoption, and usefulness for API testing and automation. The page reports four million users, 46,000 stars, and more than 500 contributors.
