Frame Rate Test started in 2022 because I got tired of how hard it was to answer simple hardware questions. If you wanted to confirm a 144 Hz monitor was actually running at 144 Hz, or check whether your mouse DPI matched what was printed on the box, the answers were buried in forum threads, hidden behind software downloads, or written for engineers instead of normal people.
So I built a browser tool to do it. That weekend project turned into thirteen free testing tools used by gamers, hardware reviewers, and curious shoppers around the world. The site has stayed independent and ad-light the whole time, and it always will.
Two ideas have shaped every decision since 2022. The first is what the site does today. The second is where it is heading.
Anyone who buys a monitor, mouse, or keyboard deserves a quick way to check whether it actually does what the box says. No software downloads. No paywalls. No engineering background required. The goal is simple. If you have a browser, you can run a real measurement in under a minute and trust the result.
The aim is to build the most trusted, browser-based hardware testing platform on the open internet. A site that hardware reviewers link to in articles. A site that Discord communities recommend without thinking. A site that does its job so well people forget to question it. That is the bar.
The story is short. In early 2022, I bought a 144 Hz monitor for a competitive gaming setup and could not find an easy way to verify it was actually running at 144 Hz. The Windows display settings showed the right number. The monitor menu showed the right number. But the way colors smeared during fast camera turns made me suspect something was off.
Every solution I found involved either downloading a third party utility, running a command line tool, or trusting a screenshot someone posted on Reddit three years earlier. None of that felt acceptable for what should be a five second check.
That weekend, I learned that the browser already had everything needed. The requestAnimationFrame API fires once per display refresh cycle. A small delta timing loop produces an accurate Hz reading inside any modern browser. The first version of the refresh rate test went live a few days later, and the response from gaming communities was immediate.
Every tool that followed came from the same pattern. Someone in a Discord would ask a question. How do I check my real mouse DPI without proprietary software. Is my keyboard registering every key during fast typing. Is my gamepad showing stick drift. Each question became the next tool. By the end of 2022 there were four. By mid 2023 there were eight. Today there are thirteen, and the list keeps growing as people keep asking.
In 2022, confirming a monitor refresh rate or measuring real mouse DPI meant installing utilities, fighting with command line tools, or trusting old forum tutorials. None of it was friendly to the average user, and a lot of the advice was outdated.
requestAnimationFrame, raw mousemove deltas, and keyboard event listeners give browser tools the same precision as native software for most testing purposes. The trick was wiring them up properly and explaining the results in plain language.
What started as a single refresh rate tester has grown into a complete browser-based testing suite covering displays, mice, keyboards, and gamepads. None of it required venture funding, a big team, or a paid plan.
Frame Rate Test is owned and operated by one person. Every tool, every guide, and every line of code on this site comes from the same place. Here is who runs it.
Tyzhon has spent the last decade building browser-based tools and writing about consumer technology. He started Frame Rate Test in 2022 as a personal project after getting frustrated with how complicated hardware testing had become. He still writes most of the code, owns the editorial calendar, and replies to every email that lands in the inbox personally. The site has no investors, no venture money, and no plans to take any. The goal has always been to keep it useful, keep it fast, and keep it free.
Every tool here exists because someone needed it. Here is how the site grew from a weekend project in 2022 into the platform it is today.
The first two tools ship within a few weeks of each other. The refresh rate tester uses requestAnimationFrame delta timing to detect monitor Hz in seconds with no install required. The frame rate test measures browser rendering performance under configurable stress loads. Both spread quickly through gaming communities. By the end of the first year, daily test volume is in the thousands.
The Mouse Polling Rate Test ships first, using mousemove event frequency to measure how often a mouse reports its position per second. The Mouse DPI Analyzer follows shortly after, using raw pointer deltas plus a physical ruler to calculate real DPI on all four axes. No browser-based versions of either tool existed before this, which is why both got picked up by hardware reviewers within weeks.
Four new display tools land back to back. The Dead Pixel Test cycles through solid colors to surface stuck pixels. The Dead Pixel Fixer attempts repair through rapid color cycling on a draggable target. The Screen Bleeding Test gives a pure black canvas for spotting backlight bleed and IPS glow. The Display Test bundles sharpness, gradient banding, and color uniformity checks into one place.
The Keyboard Tester visualises every keystroke in real time and flags ghosting and rollover problems. The Spacebar Clicker measures click speed across six timer modes with personal best tracking. The Mouse Scroll Wheel Test catches skipped steps, reversed scrolling, and step inconsistency. By year end, the site covers every input device a typical PC user owns.
The dedicated FPS Test launches as a deeper version of the original frame rate tool. It adds timed sessions, 1 percent Low tracking, frame time analysis, and a consistency score for serious benchmarking. The Gamepad Tester rounds out the controller side with full button, stick, drift, and vibration coverage using the Gamepad API.
The Frame Rate Test page picks up several advanced features over 2025 and into 2026, including a Frame Drop Detector, a Performance Score system, Device Tier comparisons, an Hz Compatibility Checker, and a WebGL Extreme Stress Test. In May 2026 the site crosses 750,000 total tests run since launch. Plenty more tools and updates are still on the roadmap.
Google evaluates websites on four signals known as E-E-A-T. Experience, Expertise, Authoritativeness, and Trustworthiness. Here is exactly how Frame Rate Test demonstrates each one.
Frame Rate Test has been running and getting active updates since 2022. Across four years, every tool has been refined repeatedly based on real measurement results, browser API changes, and feedback from people testing on hardware the founder will never own personally. That track record matters because most online testing tools either get abandoned or never get past version one. This one has not.
The tools here are built by someone who actually understands the difference between OS accelerated pointer movement and raw hardware input, between perceived frame rate and measured frame time, and between advertised DPI and the number the sensor actually outputs. That distinction is why our results match professional benchmarking software within a percent or two, while many simpler online tools produce numbers that drift by 20 percent or more.
Thirteen browser-based hardware testing tools live on a single domain. No other free, no-install platform covers this much ground. Tools from the site get linked in hardware review articles, recommended in PC building Discords, and shared in monitor and mouse subreddits without us asking anyone to do it. That kind of organic adoption is the only authority signal that actually means something.
Every test on this site runs entirely inside your browser using JavaScript. Your FPS readings, DPI measurements, polling rate data, keystroke logs, and click counts never get sent to any server. There is no database of user performance results sitting on the backend. The site does not sell data, does not run trackers beyond basic page view analytics, and does not require an account for anything. Your hardware measurements belong to you and only you.
These are not marketing words. These are the actual principles behind every product decision since the site went live.
Every tool has been free since launch and will stay that way. No premium tier. No locked features. No email signup walls. The cost of running a browser tool is small enough that asking users to pay for it would be ridiculous, and so we never have.
Where there is a tradeoff between an accurate result and a convenient one, we go with accuracy and explain why. The DPI analyzer needs a real ruler because that is the only way to measure DPI honestly. We do not pretend otherwise just to make the user experience smoother.
Every tool page explains how the measurement works, which browser API it uses, what can throw off the numbers, and what the result actually means. People making real decisions about real hardware deserve to know how their tools work, not just what the readout says.
All tests run in the browser with zero data leaving your machine. No backend logs of performance results. No tracking of individual test sessions. Analytics cover anonymous page visits only, and even those are kept minimal. Your measurements are yours.
Every tool is built to run on desktop, laptop, tablet, and phone. We test across Windows, macOS, Android, and iOS before any new feature ships. If a tool breaks on a device, that is treated as a bug worth fixing, not a corner case worth ignoring.
Frame Rate Test is not a finished product. Tools get updated when browser APIs change. Content gets refreshed as new monitor and mouse tech ships. New tools land when real users keep asking for the same thing. The site you use today is meaningfully better than the one that went live in 2022, and that is the point.
Every tool here is built around a real hardware question that real users keep asking. Here is what each one covers and why it exists.
Measures browser rendering frame rate using requestAnimationFrame. The dedicated FPS Test adds timed sessions, 1 percent Low tracking, frame time analysis, and a consistency score for benchmarking sessions that need real depth.
Detects your monitor's true Hz automatically using delta timing. Spots cases where a 144 Hz monitor is silently running at 60 Hz or where a cable is bottlenecking the refresh rate. No download, no setup, results in seconds.
Counts how many position reports per second your mouse sends to the system by tracking mousemove event frequency. Shows live Hz with a consistency score and supports readings up to 8000 Hz for high-end gaming mice.
The DPI Analyzer measures true DPI using physical ruler distance and raw browser pointer deltas across all four axes. The Scroll Wheel Test catches direction errors, skipped steps, and step inconsistency that suggests an aging encoder.
The Keyboard Tester lights up every key you press and surfaces ghosting and rollover problems. The Spacebar Clicker measures pressing speed across six timer modes from 5 seconds to 100 seconds with personal best tracking and a clear performance rating.
Full controller diagnostic using the browser Gamepad API. Tests every button, both analog sticks for drift and dead zone, both triggers for travel, and the rumble motors. Works with Xbox, PlayStation, Nintendo, and most generic USB gamepads.
The Dead Pixel Test cycles through solid color screens to expose dead, stuck, and hot pixels on any display. The Dead Pixel Fixer uses rapid color cycling over a draggable target zone to attempt repair on stuck pixels using a session timer of up to 10 hours.
The Display Test bundles sharpness, gradient banding, color uniformity, and viewing angle checks into one tool. The Screen Bleeding Test uses a pure black full-screen mode to expose backlight bleed, IPS glow, and edge light leakage on LCD, IPS, VA, and OLED panels.
Over three quarters of a million tests have been completed since 2022. Whether you are confirming a new monitor, checking a mouse before a tournament, or troubleshooting a hardware problem, the right tool is one click away.
