Bruno is an open-source desktop API client that stores every collection as plain-text Bru files on your filesystem instead of in a vendor cloud. It helps developers and teams explore REST and GraphQL APIs, run automated checks, and version their API work in Git alongside their code. It serves developers who want a fast offline client, and teams that treat API collections as reviewable source files.[1][2]
Quick verdict
Teams that version API collections in Git and want a client that works fully offline benefit most from Bruno. Its Bru plain-text format keeps every request diffable and mergeable, and the Bru command-line tool runs collections with exit codes in CI pipelines and Docker. Teams that need built-in cloud sync, hosted shared workspaces, or managed collaboration should choose something else. If an offline Git-native API workflow fits your team, choose Bruno; if hosted team collaboration is the requirement, Postman remains the incumbent choice.[1][2][3]
Capabilities
Bru plain-text collections Every request, environment, and test is stored as human-readable Bru markup in folders you own, making collections diffable, reviewable, and mergeable in Git.[1][2]
Offline-only desktop client The client runs with no account or cloud sync, so internal endpoints and secrets never leave your machine through vendor sync.[1][2]
Multi-protocol requests REST and GraphQL are core, with SOAP, WebSocket, gRPC, and OpenAPI collection support for broader API surface coverage.[1]
Environments and variables Named environments with variables switch requests between targets, including loading values from .env files.[1][2]
Scripting, tests, and assertions Pre-request and post-response JavaScript plus a testAssertion expression syntax with assert helpers validate status, headers, and JSON bodies.[1][2]
Dynamic value helpers Built-in Math, Date, and UUID helpers generate timestamps, random values, and identifiers inside requests and assertions.[1]
One-click migration Bruno imports collections from Postman, Insomnia, and OpenAPI files, lowering the cost of leaving a cloud client.[1][2]
Bru CLI and Docker The bru run command executes collections with environment selection, HTML reports, and exit codes for CI pipelines, with Docker images for containerized runs.[1][2]
Who it fits
Git-disciplined API teams gain pull requests, code review, and history on collections that live as Bru files alongside application code.[1][2]
Offline and privacy-sensitive developers get no-account local execution with secrets staying on their machines rather than syncing to a vendor cloud.[1][2]
CI-driven testers can gate pipelines on collections using the Bru CLI exit codes, environment flags, and Docker images.[1][2]
Boundaries to check
Bruno offers no built-in cloud sync or hosted shared workspaces by design; teams depending on managed collaboration will miss Postman-style workspaces.[1][2]
Scripting, assertions, and Git workflows assume developer comfort, so non-technical users get less hand-holding than in a hosted no-code client.[1][2]
SSO, dedicated support, and enterprise agreements sit in paid editions; evaluate the paid tier deliberately rather than assuming the free core covers them.[1]
Reported experience

The inspected publisher guides describe Bruno as lightweight, private, and affordable, while noting a smaller ecosystem and thinner collaboration story. These are vendor blogs, not independent user reports, and no accessible Reddit or G2 firsthand reports were found: G2 lists zero Bruno reviews.[1][2]
