Postman is a aPI development platform for designing, testing, documenting, and monitoring APIs. It handles collections, mock servers, monitoring, and docs, and it's best suited for api developers wanting a complete api platform. It has been around since 2012, giving it a 14-year head start in building out integrations and refining the product.

The free plan is free for 3 users — enough for most people to evaluate whether it fits.

pros

  • Includes Mock Servers as a core feature, purpose-built for api development workflows
  • Free for 3 users — generous enough for most small teams to get real work done
  • Established product with 14+ years on the market and a mature ecosystem

cons

  • Free plan exists but key features are locked behind the paid upgrade
  • Fewer built-in features means you may need additional tools to cover gaps
  • Ecosystem of third-party integrations is smaller than the market leaders in api development
  • Mobile experience lags behind the desktop version in features and polish
