For teams checking whether applications behave as expected, functional testing software can cover different platforms and ways of authoring tests. Compare web, mobile, and desktop app coverage, along with cross-browser support and authoring mode. Parallel runs and a self-hosted option may matter to your testing setup, while free plans and paid-from pricing add cost considerations. Maestro, testRigor, and Cypress are among the entries, as are BugBug and ACCELQ. Use the listed coverage and deployment details to assess which options suit the applications you need to test and how you want to run checks.
