Bruno Review
Bruno is an open-source, local-first API client for REST, GraphQL, gRPC, and WebSocket that stores collections as plain-text Git files with no cloud sync.
Verdict
Bruno is the leading open-source challenger to Postman, distinguished by its fully local architecture — collections live as files in your repo, there's no login, no cloud sync, and no AI training on your data. This makes it especially attractive for security-conscious teams and enterprises who already use Git for access control. The tradeoff is that real-time cloud collaboration features found in Postman or Insomnia are absent by design.
What it does
Bruno is the Git-native API client for REST, GraphQL, gRPC and Websocket. A local and open-source solution to Postman. Fast, developer-first, and no cloud syncing.
Best for
Developers and organizations prioritizing security, efficiency, and local data control.
