Pick WireMock when

  • Java and Spring Boot teams
  • Microservices integration testing
  • Teams blocked by unstable third-party APIs
  • Enterprise platform teams standardizing mocks

When WireMock is not a fit

  • Developers needing one-off quick mocks . Postman's built-in mock server suffices
  • Spec-first contract testing purists . critics say it ignores API specs
  • Non-developers . this is a CLI/library developer tool
  • Guess: frontend-only mocking of your own backend . lighter tools fit better

Pick Keploy when

  • API-heavy dev teams
  • Teams wanting tests from real traffic
  • CI/CD pipeline owners
  • Open-source-first shops

When Keploy is not a fit

  • Orgs that can't patch agents promptly . known TLS-key CVE
  • Buyers needing published pricing and mature enterprise support
  • No-code QA teams . look at ACCELQ instead
  • Tiny side projects . manual tests beat running an agent
