Bruno vs Postman vs Insomnia (2026): Which API Client Should You Use?
Bruno, Postman and Insomnia compared after Postman's 2026 free-plan change: storage model, team pricing, Git workflow, privacy and which API client fits your team.

Verdict
Bruno is the best default for most developers and small teams: free, offline, and collections live as plain files in Git. Insomnia is the middle ground when you want per-project choice of local, Git or cloud storage. Postman is worth paying for only when its platform features — mock servers, monitors, governance — are central to how your team works.
For years, choosing an API client meant installing Postman and moving on. In 2026 that default broke. Since March 2026 Postman's free plan has been limited to a single user, so a five-person team that paid nothing the year before now faces a paid Team plan. At the same time, Bruno — an open-source client that stores collections as plain-text files in your repository — has become one of the most-starred developer tools on GitHub. The choice is now less about features than about where your API collections live and what collaboration costs. (Pricing below comes from vendor pages and independent 2026 comparisons as of October 2026; check current plans before you buy.)
| Feature | Bruno | Postman | Insomnia |
|---|---|---|---|
| Storage model | Plain-text .bru files in your Git repo | Cloud workspaces | Local, Git or cloud — chosen per project |
| Account required | No | Yes | Optional for local use |
| Free plan | Core features free and open source | Single user only (since March 2026) | Free tier available |
| Paid tiers | Pro ~$6, Ultimate ~$11 per user/month | Solo ~$9, Team ~$19, Enterprise ~$49 per user/month | From ~$5 per user/month |
| 5-person team, per year | $0 on the free core | ~$1,140 on Team | ~$300 |
| Collaboration | Through Git pull requests | Real-time shared workspaces | Git sync or cloud |
| Best for | Git-native teams, privacy | Large orgs using the full platform | Mixed teams, GraphQL, Kong users |
Bruno
Pros
- Collections are plain text in your repository, so API requests are reviewed, versioned and branched exactly like code.
- No account, no cloud sync and no telemetry — requests and secrets stay on your machine.
- The open-source core is free for any team size, which removes the per-seat cost entirely for many teams.
- Large and fast-growing community.
Cons
- Collaboration happens through Git, which suits developers but not non-technical stakeholders who want a shared web workspace.
- Fewer hosted platform features (monitors, hosted mock servers, API governance) than Postman.
- Bruno replaced its one-time "Golden Edition" licence with Pro and Ultimate subscriptions for advanced features.

Postman
Pros
- The broadest platform: testing, mock servers, monitors, documentation, API governance and a large public API network.
- Real-time collaboration in shared workspaces suits large, mixed teams.
- Mature enterprise controls and integrations.
Cons
- The free plan is single-user, so collaboration starts at a paid seat for every teammate.
- Data lives in Postman's cloud by default, which some security teams reject for sensitive APIs.
- The most expensive option per seat.
Insomnia
Pros
- The only one of the three that lets each project choose local, Git or cloud storage.
- Strong GraphQL, gRPC and WebSocket support, with a lightweight interface.
- Natural fit for teams already using Kong's API gateway (Kong owns Insomnia).
- Paid plans priced well below Postman.
Cons
- Its history includes a forced-account change that pushed some users away; check that current storage defaults match your policies.
- Smaller ecosystem than Postman and less community momentum than Bruno.
Which should you choose?
Start with Bruno: if your team already reviews code in Git, it may be all you need, at no cost. Move to Insomnia when you need flexibility over where each project's data lives, or you work heavily with GraphQL or Kong. Choose Postman only when its platform features — monitors, mocks, governance, shared workspaces for non-developers — are genuinely load-bearing. A sensible migration test: export one real Postman collection, import it into Bruno and Insomnia, and run it in CI with each.
