Bruno

Bruno is a Git-oriented API client for developers and teams that keep engineering work in repositories. It is strongest when requests, tests, and documentation should travel with source code; teams wanting a primarily cloud-hosted workspace should look elsewhere. The free tier is useful for smaller projects, while serious automation and synchronization work points toward the paid plans.

Overview

Bruno saves API collections as plain-text files inside a project repository, making changes reviewable and versionable with Git. That is a practical advantage for code-centric teams: API examples and test behavior can be reviewed alongside application changes instead of living in a separate workspace. Collections, environments, and secrets remain on the device, and Bruno says it does not store user data in the cloud.

Local storage has an important qualification. At startup, the application makes an outbound HTTPS license-validation request containing the IP address, license key, hashed device ID, and Bruno version. Bruno says project data is not sent. The company also states that Bruno is SOC 2 Type I certified and independently audited against AICPA Trust Services Criteria, with internal role-based access, multi-factor authentication, code reviews, dependency audits, and an incident-response plan.

Key features

Support covers REST, GraphQL, gRPC, and WebSocket APIs, so one collection approach can span conventional HTTP services and other common protocols. Assertions, test scripting, collection automation, scheduled runs, contract testing, and CI/CD integration make Bruno suitable for repeatable checks rather than occasional request inspection.

Multiple environments, variables, and pre-request and post-response JavaScript scripts help adapt the same collection to development, staging, and production contexts. The desktop client is complemented by a CLI and IDE extension, while a mock server supports simulated endpoints. An API documentation generator turns collections into standalone interactive HTML pages with code samples and a live playground. Integrations listed for Git providers and secret managers include Vault, Azure Key Vault, and AWS.

This breadth favors engineering teams that want one collection format across editing, automation, documentation, and mocks. It is less compelling if your priority is a shared cloud workspace rather than repository files and local data.

Pricing

Bruno has a free Open Source plan at no cost. It allows two workspaces and five OpenAPI syncs per month, with community support. That is a reasonable starting point for individual developers or small projects, but the workspace and sync ceilings can become restrictive for teams managing several APIs.

Pro costs $6 a month, billed annually. It raises workspaces to unlimited while retaining five OpenAPI syncs per month, making it the sensible step for users who outgrow the free workspace cap but do not need unlimited synchronization. Ultimate costs $11 a month, also billed annually, and adds unlimited OpenAPI syncs and unlimited license admins. Choose it when synchronization volume or administration across a larger team matters. Bruno offers a 14-day Ultimate trial with no credit card required; paid pricing is therefore easiest to assess before committing to annual billing.

Platforms

Desktop downloads are available for Windows, macOS, and Linux. Bruno also offers an API client, CLI, IDE extension, documentation generator, and mock server, giving teams options beyond the desktop interface. Its listed platform coverage includes API, extension, Linux, macOS, and Windows.

Who it's for

Bruno is a strong fit for developers, QA engineers, and small engineering teams that want API collections committed to Git, tested in CI/CD, and reused for documentation or mocking. The free plan suits personal work and modest repositories. Pro fits teams needing unlimited workspaces, while Ultimate is aimed at organizations with heavier OpenAPI synchronization and multiple license administrators.

Look elsewhere if your team expects cloud-first collaboration, or if the startup license-validation request conflicts with your network or privacy requirements.

Pros and cons

Pros

• Git-native collections: Plain-text files make API changes reviewable and versionable with project code.
• Broad protocol coverage: REST, GraphQL, gRPC, and WebSocket support reduces the need for separate clients.
• Automation depth: Assertions, scripts, scheduled runs, contract testing, and CI/CD integration support repeatable delivery checks.
• One collection format across tools: Desktop, CLI, IDE extension, mocks, and interactive documentation build on the same data.
• Local-data model: Collections, environments, and secrets stay on the device rather than in Bruno's cloud.

Cons

• Free-plan caps: Two workspaces and five OpenAPI syncs per month limit larger or more active projects.
• Annual paid billing: Pro and Ultimate prices are quoted per month but billed annually.
• Startup network call: License validation sends device and license metadata even though Bruno says project data is excluded.
• Repository-centered workflow: Teams seeking a central cloud workspace may find local files less convenient.

Alternatives

Postman is the better choice for teams wanting a broad cloud-oriented API platform with a free tier that includes an API client, core tools, specs, mock servers, Native Git, and Collection Runner across desktop, web, and extension platforms.

Apidog suits users who prefer a time-unlimited free plan for up to four users and need a broader web, self-hosted, and desktop footprint.

SoapUI is a free alternative for focused REST, SOAP, and GraphQL testing with functional and regression testing, mocking, and command-line automation.

Insomnia is worth considering for Git Sync projects and a free allowance of three users with 1,000 mock-server requests per month.

HTTPie is the simpler free option when an offline web-and-desktop client or open-source terminal client is the priority.

Testfully is an alternative for users who want offline and cloud workspaces with invitations for up to five users per workspace.

Hoppscotch fits teams seeking free REST, GraphQL, and realtime API testing with personal workspaces, collections, environments, and pre-request scripts.

Hurl is a free, open-source command-line tool when a terminal-first workflow is sufficient.

Verdict

Choose Bruno if your API work belongs in Git and you value one collection format for testing, automation, documentation, and mocks. Its local-storage approach and protocol coverage are compelling for repository-centered teams. Choose another client if cloud collaboration is central, the free sync limits are too tight, or the startup license-validation request is unacceptable.
