Functional testing software helps you check whether applications behave as expected. Compare web, mobile, and desktop app coverage alongside cross-browser support and authoring mode to see what each option can address. Parallel runs and a self-hosted option may also affect how testing fits your setup. Free plans and paid-from prices are useful cost points to weigh.
