Postman vs Insomnia
Which automation & integration tool is right for you? Compare features, pricing, and user reviews to make the best choice.
Postman
Teams that share API collections across developers, QA and partners and want testing, monitoring, mocks and docs in one cloud platform, and can justify a per-seat price.
Insomnia
Teams that need a choice of where API data lives (some projects local-only, others shared through Git or cloud), and teams already using Kong Gateway or Konnect.

Pros and cons
Postman
Pros
- Broadest feature set of any API client here
- Postman collection format is the de facto standard; many vendors publish collections
- Built-in monitoring and mock servers, no extra tools needed
- Postman CLI runs collections in CI
- Mature roles and workspace governance on paid plans
Cons
- Free plan is limited to 1 user, so any team pays from the second seat
- $19/user/month (annual) is the highest standard team seat price among the clients here
- Cloud-first: collections sync to Postman by default
- Private API Network, Insights and included SSO are Enterprise-only
Insomnia
Pros
- Choose local, Git or cloud storage per project
- Apache-2.0 open-source client with plugins
- Broad protocol support including gRPC and SSE
- Built-in OpenAPI design mode and mocks
- Pairs naturally with Kong's gateway products
Cons
- Free Git Sync is capped at 3 users
- Enterprise at $45/user/month is the priciest seat on this page
- Past account and sync requirement changes left some users wary
- Smaller ecosystem of vendor-published collections than Postman

Best API Testing and Management Tools
For API testing, pick Postman if your team collaborates heavily and wants monitoring built in, or Bruno if collections should live in Git. Add Stoplight for design-first API programs and Kong only when you need a production gateway.

If you only use Postman to send requests and run tests, switch to Bruno for a free, Git-first setup, or Insomnia for the closest like-for-like tool. Stay on Postman if you rely on its monitors, governance or API catalog.
