**APIs profiled:** 5

Bruno is an open-source (MIT), git-native API client - a lightweight, offline-first alternative to Postman and Insomnia for exploring and testing APIs. It is a developer TOOL, not a hosted HTTP API provider. Collections are stored on the local filesystem as folders of plain-text files (the .bru "Bru" markup language, with OpenCollection YAML now recommended for new collections), so API requests are version-controlled in Git alongside code. Bruno sends HTTP, REST, GraphQL, and gRPC requests, manages environments and variables, and runs pre-request/post-response scripts, tests, and assertions. The @usebruno/cli command-line runner (bru) executes collections headlessly in CI/CD with JSON, JUnit, and HTML reporters. Bruno is offline-only and does not sync request data to a Bruno-hosted cloud; paid Pro/Ultimate tiers add native in-app Git integration, OpenAPI sync, and enterprise admin controls that run through your own Git provider and identity systems. Bruno does not expose a documented public REST HTTP API.
