Best API Testing Tools in 2026
Updated
In short: Apidog is ranked #1 of 35 as of 4 October 2026, ahead of Hoppscotch and Pact. The best-ranked option with a free plan is Hoppscotch. The lowest first paid tier on this page is Bruno at $0.50/mo.
API testing tools support work such as sending requests, checking contracts, and integrating tests into development workflows. The entries are ranked, with Postman, Apidog, and SoapUI among those at the top. Compare CI/CD integration and contract testing with GraphQL and SOAP support, then consider whether mock servers or scheduled runs fit your testing process. Included requests and free-plan availability can help you understand what is available before a paid tier, while paid-from pricing offers another comparison point. Focus on the capabilities that match the APIs you handle and the way you run tests.
35 API testing tools ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
