Our Mission
FPSCheck was founded with a simple mission: provide free, reliable, and transparent performance testing tools that work in any browser, on any device, without requiring downloads or installations.
Too many "FPS test" websites are filled with ads, misinformation, or require you to download suspicious software. We believe performance testing should be simple, instant, and trustworthy.
Meet the Founder
Muzamil Ahad
Founder & Web Developer
Muzamil Ahad is a passionate web developer and gaming enthusiast who created FPSCheck to provide the gaming community with an accurate, free, and privacy-respecting performance testing tool. With years of experience in web development and a deep understanding of browser rendering technologies, he ensures that our tools use the most accurate measurement methods available.
How Our Technology Works
All of our tests run entirely client-side in your web browser. Here's what powers each tool:
FPS Counter
Our FPS counter uses the browser's requestAnimationFrame() API — the same underlying mechanism that powers smooth web animations. By counting how many times this callback fires per second, we get an accurate measurement of your browser's rendering frame rate, which directly mirrors your display's refresh capability.
Real-Time Graph
The performance graph is rendered using the HTML5 <canvas> API. It draws a new data point every second, scrolling from right to left, creating a real-time visualization of your FPS stability over 60 seconds.
Stress Test
The stress test generates DOM-based particles (colored circles) that animate across the screen using CSS transforms with will-change: transform. This forces the browser's compositor and GPU to work harder, allowing you to see how your system handles increasing visual load.
Refresh Rate Detection
Our refresh rate tool measures the interval between requestAnimationFrame callbacks. Since browsers sync this callback to V-Sync by default, the measured frame rate directly corresponds to your monitor's active refresh rate.
Our Values
Privacy First
We don't collect personal data. All tests run locally in your browser. We don't track your hardware specs or performance results.
Performance
Our website is lightweight and fast-loading. No heavy frameworks, no unnecessary dependencies. Just clean HTML, CSS, and JavaScript.
Accessibility
We strive for WCAG 2.1 AA compliance. Our tools work on desktops, laptops, tablets, and phones across all modern browsers.
