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.
Bruno publishes 6 APIs on the APIs.io network. Tagged areas include API Client, API Testing, Developer Tools, Open-Source, and Git-Native.
Bruno’s developer surface includes documentation, engineering blog, and 7 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bruno-api: open an issue to ask a question, or submit a pull request to add artifacts.

description: Bru is Bruno's plain-text domain-specific markup language. Each request is stored as a .bru file capturing
the HTTP method, URL, query params, headers, body, authentication, scripts, tests, assertions, and variables, so a collection
is a folder of human-readable text files reviewable in Git pull requests. A logical artifact/file format modeled as a
capability area - not an HTTP endpoint.

individual requests or entire collections headlessly for CI/CD, with JSON, JUnit, and HTML test reporters, environment
selection, and assertions. Since v3.0.0 it defaults to Safe Mode for security; Developer Mode features (filesystem access,
external npm packages) require the --sandbox=developer flag. A local CLI tool, not a hosted API.

description: Bruno is an open-source API client for exploring and testing REST, GraphQL, and gRPC APIs. Collections are
stored as plain text Bru files on the filesystem, enabling Git-based version control, team collaboration through pull
requests, and co-location with application code. Bruno supports JavaScript scripting, environment variables, collection-level
authentication, and CI/CD execution via Bruno CLI. No cloud account required.
