Bruno vs Postman: Which API Client Is Better for Developer Teams in 2025

Bruno vs Postman: Which API Client Is Better for Developer Teams in 2025

Postman has dominated the API client market for nearly a decade. With more than 35 million registered users and a valuation that peaked around $5.6 billion, it became the default tool for testing endpoints, documenting APIs, and sharing collections across teams. But a quieter shift has been underway since 2022, when a small open-source project called Bruno started gaining traction on GitHub. By early 2025, Bruno had crossed 30,000 GitHub stars, and its pitch—a fast, offline-first, Git-native API client—was resonating with teams frustrated by Postman’s cloud dependency, account requirements, and pricing changes.

So which tool actually fits a developer team in 2025? The answer depends less on feature checklists and more on how your team works.

The Core Philosophical Difference

Postman is a platform. It stores collections, environments, mock servers, and documentation in the cloud, tied to your Postman account. Collaboration happens through Postman’s servers, and the free tier limits how many people can work together.

Bruno is a local-first tool. Collections are stored as plain-text .bru files on your filesystem. You version them with Git, review changes in pull requests, and share them the same way you share code. There is no mandatory account, no cloud sync, and no vendor lock-in.

This distinction drives almost every practical difference between the two tools.

Collaboration and Version Control

For teams that already live in Git, Bruno’s model feels natural. A collection is a folder of human-readable files. When a developer adds an endpoint or changes an environment variable, it shows up as a diff in a pull request. Reviewers can comment on specific request changes before they merge.

Postman’s collaboration model centers on workspaces. Teams share collections through Postman’s cloud, and while Postman supports Git-based version control on paid plans, the workflow is bolted onto the platform rather than native to it. Free-tier teams are limited to a small number of collaborators and a capped number of shared requests.

If your team values code review culture and wants API changes to go through the same pipeline as application code, Bruno has a structural advantage. If your team includes non-engineers—QA analysts, product managers, technical writers—who need a polished UI without touching a terminal, Postman’s workspace model is easier for them to adopt.

Pricing in 2025

Postman’s pricing has shifted meaningfully over the years. The free tier remains functional but restricts collaboration. Paid plans start around $14 per user per month for the Basic tier and climb to roughly $49 per user per month for Enterprise, billed annually. For a 20-person team, that’s between $3,400 and $11,800 per year.

Bruno is free and open source, with an optional paid tier (Bruno Plus, around $6 per user per month) that adds features like a built-in secret manager and team-level preferences. There is also a self-hosted enterprise option. For budget-conscious teams, the cost difference is substantial—but it’s worth noting that Postman’s price includes hosting, sync infrastructure, and support that Bruno’s free tier does not.

Features and Daily Workflow

Postman has had years to build out its feature set. It supports REST, GraphQL, gRPC, WebSocket, and SOAP. It includes mock servers, automated testing with JavaScript assertions, a CLI (Newman) for CI pipelines, API documentation generation, and monitoring. The API network—a public directory of APIs—is a differentiator if your team discovers and integrates third-party APIs frequently.

Bruno covers the essentials well: REST and GraphQL, environment variables, scripting with JavaScript, a CLI (bru) for CI, and collection runners. It has added gRPC and WebSocket support, though its ecosystem of integrations is thinner. Some advanced Postman features—like sophisticated mock servers and the public API network—don’t have direct equivalents.

For most day-to-day API testing, Bruno is sufficient. For teams that rely heavily on Postman’s broader platform features, switching means finding replacements.

Performance and Offline Use

Bruno is built on a lighter stack and generally launches faster and uses less memory than Postman’s Electron-based desktop app. Developers who work on planes, in air-gapped environments, or behind restrictive corporate networks often cite offline reliability as a deciding factor. Postman requires connectivity for most collaborative features, though the desktop app caches recent work.

Security and Data Residency

Because Bruno stores everything locally, sensitive API keys and tokens never leave the developer’s machine unless the team chooses to commit them (which they shouldn’t). Postman stores data in its cloud, which raises questions for teams in regulated industries. Postman offers SOC 2 compliance and enterprise controls, but some organizations—particularly in finance, healthcare, and government—prefer keeping API collections entirely on-premises. Bruno’s self-hosted option addresses this directly.

Where Each Tool Wins

Bruno is the better fit when:

• Your team is engineering-heavy and already uses Git-based workflows
• You want API collections reviewed alongside code
• Budget is a constraint or you’re scaling a large team
• You work offline or in restricted network environments
• You prefer open-source tools with no vendor lock-in

Postman is the better fit when:

• Your team includes non-engineers who need a polished GUI
• You rely on mock servers, the public API network, or advanced monitoring
• You want a managed platform with support contracts
• Your team is small and the free tier covers your needs
• You value a mature ecosystem with extensive documentation and tutorials

A Practical Middle Path

Some teams use both. Bruno handles day-to-day development and version-controlled collections; Postman handles exploratory testing, documentation sharing, and stakeholder demos. Since Bruno can import Postman collections (and vice versa), migration isn’t all-or-nothing.

The Takeaway

There’s no universal winner in 2025. Postman remains the more complete platform, with features and polish that come from a decade of investment—and a price tag to match. Bruno offers a leaner, Git-native, offline-first alternative that fits teams who treat API definitions as code and want to avoid recurring per-seat costs.

The right question isn’t which tool is objectively better. It’s whether your team’s workflow is built around a cloud platform or around version control. Answer that, and the choice becomes obvious.
