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.
Stoplight
Teams that design API contracts before writing code, need consistent API style across several teams, or publish polished docs from OpenAPI.

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
Stoplight
Pros
- Visual editor makes OpenAPI usable for non-YAML writers
- Docs and mocks come straight from the spec
- Spectral and Prism are free and work in CI
- Included-user pricing is good value on Basic and Startup
Cons
- Not a day-to-day API testing client
- Governance and SSO only from Pro Team ($362/month annual)
- Long-term roadmap under SmartBear is worth confirming
- Overlaps with Postman Spec Hub and Insomnia design mode for light needs

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.
