What is FPS Tester?
FPS Tester is a free, browser-based set of performance tools. It lets you run a live FPS check right in the browser, without installing anything or creating an account. The main test shows how often your browser can complete visual updates, then helps you see how performance changes under different stress levels from light to heavy. It also includes side-by-side frame rate comparisons so you can judge motion smoothness at different FPS levels, plus related tools for refresh rate and reaction time. The site is meant for quick performance checks, troubleshooting, and comparing browser behavior under load, rather than replacing in-game benchmarks. It works as a simple way to understand how smooth your browser feels on your device.
