Postman is a cloud-connected API client with the largest feature set and ecosystem โ team workspaces, hosted mock servers, and a polished GUI โ but it ties your collections to an account and applies usage limits on its free tier. Bruno is a free, open-source, offline-first alternative that stores each request as a plain text file, so collections live in your git repo and get reviewed like code, with no account required. Choose Postman for maximum built-in tooling and a larger team already invested in its ecosystem; choose Bruno if git-native collaboration, offline use, or avoiding cloud storage of your API data matters more to your team.
- Postman syncs collections to the cloud by default; Bruno stores them as local
.brufiles you control. - Bruno's file-based format is git-friendly โ diffs are readable and collections merge like code.
- Postman has the deeper feature set: hosted mock servers, API documentation publishing, and a larger integration ecosystem.
- Both support scripting, environments, and a CLI test runner (Newman for Postman, Bruno's own CLI for Bruno).
- Bruno's core app is free and open source with no request limits; Postman's free tier has usage limits that scale with paid plans.
Every API testing workflow starts somewhere, and for most developers that's Postman โ it's been the default for years. Bruno is the newer, faster-growing alternative built around a different core idea: your API collections should live in your codebase as plain files, not locked inside a cloud account.
Neither tool is objectively "better" โ they're built around different assumptions about where your data should live and how your team collaborates. This comparison walks through the real differences so you can pick the one that actually fits your workflow.
Quick Overview
Postman launched in 2012 and has grown into a full API platform: request building, automated testing, mock servers, documentation, and monitoring, all built around cloud-synced workspaces. Bruno launched in 2023 as a direct response to Postman's move toward cloud-mandatory workflows โ it deliberately stores everything locally as readable text files, with git as the collaboration layer instead of a proprietary sync service.
Cloud-First vs Local-First
The single biggest difference between these tools isn't a feature โ it's where your data lives, and that one decision shapes almost everything else about how each tool behaves.
.bru file in a local folder, using git as the sync and collaboration layer instead.Neither model is universally "more secure" or "more collaborative" โ they trade off differently. Postman's cloud sync makes real-time collaboration and onboarding effortless; Bruno's local files make code review, offline work, and full data ownership effortless instead.
Feature Comparison at a Glance
Here's how the two stack up across the factors teams care about most:
Detailed Feature Breakdown
| Feature | Postman | Bruno |
|---|---|---|
| Collection storage | Cloud workspace (with local export option) | Local .bru text files |
| Scripting | JavaScript pre-request/test scripts | JavaScript pre-request/post-response scripts |
| Environments & variables | Yes, with secret masking | Yes, with secret masking |
| CLI test runner | Newman | Bruno CLI (bru run) |
| Mock servers | Hosted mock server platform | Basic local mocking; less mature than Postman's |
| API documentation publishing | Built-in, hosted docs generator | Not a built-in feature |
| GraphQL support | Yes | Yes |
| gRPC support | Yes | Yes (added more recently) |
| Offline use | Works, but core workflow assumes an account | Fully functional with no account or internet |
| Version control fit | Requires exporting JSON to diff meaningfully | Native โ plain text files diff cleanly in git |
Pricing Comparison
Pricing details change often on both sides, so treat the numbers below as directional rather than exact โ always check each vendor's current pricing page before budgeting.
- Postman follows a freemium SaaS model: a free tier covers individual use with usage limits (API call caps, collaborator limits), and paid tiers unlock higher limits, team features, and advanced governance/security controls for larger organizations.
- Bruno's core desktop app is open source and free with no usage limits, since there's no hosted infrastructure metering your requests. A paid offering exists for teams that want hosted secret management and centralized governance on top of the open-source core.
Collaboration and Team Workflows
Postman's collaboration model is built for real-time, low-friction sharing: invite a teammate to a workspace and they immediately see the same collections, synced automatically. It's the fastest onboarding experience of the two, especially for non-developers like product managers or manual QA who don't want to think about git.
Bruno's collaboration model runs through your existing development workflow: a teammate clones the repo, and the API collection is right there alongside the code it tests. Changes to a request go through the same pull request and code review process as everything else โ which means API collection changes get the same scrutiny as application code, instead of being invisible edits in a separate tool.
Git Integration and Version Control
This is where the architectural difference shows up most concretely. A Postman collection exported to JSON is technically version-controllable, but a single field change can rewrite large portions of the file, making diffs nearly unreadable in a pull request. A Bruno .bru file is plain text, structured per request, so a diff shows exactly what changed:
meta {
name: Get User by ID
type: http
seq: 1
}
get {
url: {{baseUrl}}/users/:id
body: none
}
params:path {
id: 42
}
headers {
Authorization: Bearer {{token}}
}
tests {
test("status is 200", function () {
expect(res.getStatus()).to.equal(200);
});
}
A teammate reviewing a pull request can read exactly what request changed โ a header, a URL, a test assertion โ the same way they'd review any other code change.
Migrating from Postman to Bruno
Bruno includes a built-in importer for existing Postman collections:
- Export your Postman collection as JSON (Collection โ Export โ Collection v2.1).
- In Bruno, choose Import Collection and select the exported JSON file.
- Bruno converts requests, folders, and environment variables into
.brufiles automatically. - Review any pre-request or test scripts that used Postman-specific APIs (like
pm.*methods) โ these usually need small manual adjustments to Bruno's equivalent syntax. - Commit the resulting
.brufiles to your repository so the team can start collaborating on them through git.
Most teams migrate gradually โ keeping Postman for exploratory work while committing the stable, CI-tested collections to Bruno first.
Which Should You Choose?
| Choose Postman ifโฆ | Choose Bruno ifโฆ |
|---|---|
| Your team includes non-developers who need a zero-setup, cloud-synced experience | Your team wants API collections reviewed in pull requests like any other code |
| You rely on hosted mock servers or published API documentation | You want to avoid vendor lock-in and keep full ownership of where data lives |
| You're already deep in Postman's ecosystem and integrations | You work offline often, or want a tool with no account requirement |
| Budget for paid tiers isn't a concern as usage scales | You want a free tool with no usage-based limits |
Many teams end up using both: Postman for exploratory, ad-hoc API poking, and Bruno for the stable collections that get committed to the repo and run in CI. If your team is deciding how API testing fits into a broader automation strategy, our API automation testing guide covers building that CI-ready suite regardless of which client you standardize on.
Frequently Asked Questions
Bruno's core desktop app is open source and free for individuals and teams, with no request limits or account requirement for local use. Postman also has a free tier, but it applies usage limits (like monthly API request caps and collaborator limits) that scale with paid plans as team size or usage grows. Always check each vendor's current pricing page, since limits and tiers change over time.
Mostly, for core API testing workflows โ requests, environments, scripting, and collection running. Postman still has a larger ecosystem: a hosted mock server platform, a more mature GUI for API documentation publishing, and broader third-party integrations, since it's been on the market far longer.
The most common reason is git-native collaboration: Bruno stores each request as a plain text .bru file, so collections live in your existing repo, get reviewed in pull requests, and merge like any other code change. Teams that don't want API collections tied to a cloud account, or that want full control over where their data lives, also lean toward Bruno.
Yes. Bruno has a built-in Postman collection importer that converts a exported Postman JSON collection into .bru files, including most requests, environments, and variables. Complex pre-request/test scripts using Postman-specific APIs may need manual adjustment after import.
Yes, via Bruno's command-line runner, which works similarly to Postman's Newman โ pointing it at a collection folder and environment file runs the requests and reports pass/fail, making it usable as a CI pipeline step.
Either works well, but Bruno's lack of a required account and local-only storage tends to appeal to solo developers who don't need team collaboration features and prefer keeping API collections in their own project repo rather than a cloud workspace.
