API Client

The Bruno API Client is the desktop application you use to build, send, and organize API requests. Collections live as plain text files on your filesystem, so you can version them with Git and review API changes like code.

Build and send REST, GraphQL, gRPC, WebSocket, and SOAP requests. Reuse values across environments, collections, folders, and requests. Configure Basic, Bearer, OAuth 2.0, AWS Signature, and more. <Card title="Secret Management" icon="key" href="/secrets-management/overview"

Keep credentials out of version control with secret variables and vaults.

Write assertions and test suites, and automate runs with data-driven testing. Pre-request and post-response JavaScript — the bru API, request chaining, and libraries. <Card title="Git & Collaboration" icon="code-branch" href="/git-integration/overview"

Share collections with your team through your existing Git workflow.

Native AI features with your own provider keys — no data routed through Bruno servers. Build custom UIs with HTML/CSS/JS or React that interact with your APIs inside Bruno. Customize Bruno's behavior, appearance, and network configuration. Inspect the main request, script-triggered calls, and console output in one timeline.

The rest of Bruno

The API Client is one of four parts of Bruno. The others share the same collection format, so work you do in one carries over to the others.

Run the same collections from the command line and in CI/CD. Document your APIs and generate shareable documentation. <Card title="VS Code Extension" icon="code" href="/vs-code-extension/overview"

Open and send requests without leaving your editor.
