Postman is the API testing tool everyone knows. Installed on 30 million developers' machines according to official figures, it has become synonymous with API testing. But in 2026, a serious challenger emerges: Bruno, an open source API client that promises to solve the frustrations accumulated with Postman.
This comparison helps you decide if migrating to Bruno is worth it for your team, or if Postman remains the optimal choice.
Why This Comparison Now?
Growing Frustrations with Postman
Postman has evolved from a simple API testing tool to a complete platform — some would say bloatware. Recurring grievances:
- Mandatory cloud sync: Since 2023, Postman has pushed heavily toward its cloud, making offline work less smooth
- Locked collections: Proprietary JSON format that's hard to read and version
- Performance: The Electron app consumes 500MB-1GB of RAM according to community measurements
- Aggressive pricing: Essential collaborative features (team variables, mocking) are paid starting at $12/user/month
The Emergence of Bruno
Bruno arrived in 2023 with a radically different philosophy:
- Git-friendly: Collections stored as text files (Bru format) directly in your repo
- Offline-first: No cloud sync required
- Open source: MIT license, active community on GitHub (25,000+ stars)
- Lightweight: Native application, reduced memory footprint
According to npm download data, Bruno experienced 340% growth in 2025, signaling significant community interest.

Migration Scenarios
Scenario 1: Early-Stage Startup
Context: Team of 3-5 developers, limited budget, simple collections.
Recommendation: Bruno immediately. No reason to start with Postman when Bruno offers essentials for free with better Git integration.
Migration: No migration, start directly on Bruno.
Scenario 2: SME with Existing Postman Collections
Context: 10-20 developers, collections accumulated over 3+ years, Newman workflows in place.
Recommendation: Progressive migration.
Steps:
- Install Bruno alongside Postman
- Use Bruno's Postman collection import
- Migrate new collections to Bruno
- Convert old collections progressively
- Adapt CI/CD scripts (Newman → Bruno CLI)
Estimated timeline: 2-4 weeks for complete migration.
Scenario 3: Large Enterprise with Postman Enterprise
Context: 100+ developers, SSO required, strict compliance, intensive mocking.
Recommendation: Stay on Postman Enterprise. Governance features and support aren't replicable with Bruno.
Alternative: Evaluate Bruno for autonomous teams without compliance constraints.
Postman → Bruno Migration Guide
Step 1: Export Postman Collections
# Via Postman UI
Collection > Export > Collection v2.1
Step 2: Import into Bruno
Bruno supports native import of Postman v2.1 collections. Conversion to Bru format is automatic.
Step 3: Script Verification
Postman pre-request and test scripts use a specific API (pm.). Bruno uses a different API (bru.). Check and adapt:
Postman:
pm.environment.set("token", pm.response.json().token);
Bruno:
bru.setEnvVar("token", res.getBody().token);
Step 4: Environment Configuration
Create .env files for each environment:
# environments/dev.env
baseUrl=https://api-dev.example.com
authToken=dev_token_xxx
Step 5: Git Integration
# Recommended structure
api/
├── collections/
│ ├── users/
│ │ ├── get-users.bru
│ │ └── create-user.bru
│ └── products/
├── environments/
│ ├── dev.env
│ └── prod.env
└── bruno.json
Step 6: CI/CD
# .github/workflows/api-tests.yml
name: API Tests
on: [push]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- run: npm install -g @usebruno/cli
- run: bru run --env dev
Bruno Limitations to Know
What Bruno Doesn't Do (Yet)
- Server mocking: No built-in mock server. Use alternatives like Mockoon or MSW
- API documentation: No documentation generation. Use Swagger/OpenAPI
- Monitoring: No continuous monitoring. Use dedicated tools like Checkly
- Complex OAuth flows: Basic support, no automatic PKCE
Features in Development
According to Bruno's GitHub roadmap:
- Enhanced GraphQL support
- WebSocket testing
- gRPC support
- Community plugins
Other Alternatives Worth Considering
Insomnia
Originally an open source alternative to Postman, Insomnia has evolved through multiple acquisitions (Kong, now Anthropic). It offers a middle ground between Postman's feature richness and Bruno's simplicity. Key differentiators include excellent GraphQL support and a clean interface. However, its future direction remains uncertain given ownership changes.
HTTPie
For developers who prefer CLI tools, HTTPie offers a pleasant command-line experience for API testing. The desktop application provides a minimal GUI while maintaining the command-line philosophy. Ideal for developers who work primarily in terminals and want quick API exploration.
RapidAPI (formerly Paw)
A macOS-native option with excellent performance and native features. The acquisition by RapidAPI added API marketplace integration. Suitable for teams already using RapidAPI's platform, but less compelling as a standalone tool.
Thunder Client (VS Code Extension)
For teams living inside VS Code, Thunder Client provides API testing without leaving the editor. Lightweight and convenient for quick tests, though less suitable for comprehensive API development workflows. Collections are stored locally, similar to Bruno's approach.
Best Practices for API Testing Workflows
Organize Collections by Domain
Whether using Postman or Bruno, organize collections around business domains rather than technical endpoints. This makes tests more maintainable and easier for new team members to understand. Group related endpoints together and name requests clearly.
Version Control Everything
Even with Postman, export collections regularly and commit them to Git. This provides backup, enables code review of API changes, and allows rollback if needed. Bruno's native Git integration makes this automatic, which is a significant workflow advantage.
Automate Early and Often
Integrate API tests into CI/CD pipelines from day one. Catching regression bugs early in the development cycle saves significant debugging time later. Both Newman (Postman) and Bruno CLI make this straightforward to implement.
Verdict and Recommendations
Choose Bruno if:
- Your team consists mainly of developers
- You use Git to version everything
- Budget is a constraint
- You prefer open source tools
- Collections are relatively simple
- A digital audit revealed SaaS costs to optimize
Stay on Postman if:
- You need built-in mock server
- Collaboration includes non-developers (product managers, QA)
- Newman workflows are critical and complex
- SSO and compliance are mandatory
- Budget isn't a deciding factor
Alternative: Hybrid Usage
Some teams use Bruno for daily development and Postman for documentation and mocking. This approach captures the advantages of both tools but adds complexity.
Key Takeaways
The choice between Postman and Bruno isn't binary. Bruno represents a credible alternative for teams that value Git integration, lightweight design, and local control. Postman remains relevant for organizations requiring advanced collaboration and governance features.
Market trends show growing interest in "Git-first" tools like Bruno, reflecting the evolution of DevOps practices toward infrastructure as code and versioned configuration.
For Moroccan and African teams, cost savings with Bruno can represent a significant advantage, allowing budget reallocation toward other tools or training.

FAQ
Can I import my Postman collections into Bruno without loss?
Import works well for standard requests, environments, and basic tests. Complex scripts using the pm. API require manual adaptation to the bru. API. Expect 10-20% of scripts to modify for a typical collection.
Is Bruno suitable for GraphQL API testing?
GraphQL support is functional but basic compared to specialized tools like Insomnia or Apollo Studio. For intensive GraphQL projects, evaluate these alternatives or wait for planned improvements in Bruno's roadmap.
How do I manage secrets with Bruno?
Bruno Golden Edition ($19) offers encrypted secret variable support. Otherwise, use .env files excluded from Git (.gitignore) or integrate with secret managers like Vault or AWS Secrets Manager.
Is free Postman sufficient for a small team?
For 3 users or fewer with basic needs, yes. Beyond that, limitations (no team variables, restricted collaboration) become frustrating. At that point, Bruno becomes more economically attractive.
Are there plugins or extensions for Bruno?
The plugin ecosystem is nascent. The community develops extensions, but nothing comparable to the richness of the Postman ecosystem. Check specific needs before migrating if you depend on particular Postman plugins.
