Free Browser Tests for Your Gaming Setup
Free browser tests to check and tune your gaming setup: controller, keyboard, mouse, monitor, mic, webcam, headset. Nothing installed or uploaded.
A stick that drifts, a key that drops inputs, a mouse that double-clicks on its own, a 144 Hz monitor quietly running at 60 -- every one of those loses you rounds, and every one shows up in a browser test in under a minute. Each tool here exercises one piece of your setup through the browser's own device APIs and shows you exactly what it reports, so you know whether to adjust a setting, clean a switch, or send the thing back.
Everything runs locally. No installs, no accounts, and nothing you type, say, or show the camera leaves your machine.
Reaction, aim & click speed
Wait for green, then click or hit space. Five rounds with random delays give your average, median, and best reaction time in milliseconds.
Aim TrainerClick targets as they appear for 15-60 seconds and get hits, accuracy, and average time-to-target, for before-and-after sensitivity changes.
CPS TestClick speed test from 1 to 60 seconds. Starts on your first click and reports clicks per second, with a session best.
Controller, keyboard & mouse
Plug in a controller and watch every button, trigger and stick respond live, with stick drift read off the axes. Xbox, PlayStation, Switch Pro, generic.
Stick Drift TestTime a 10-second hold-still test on both analog sticks and get a max/mean deviation reading, a none/minor/repair verdict, and a recommended dead zone.
Keyboard TesterPress any key and see it light up on a full layout. Find dead keys, stuck keys, and check what each key actually sends before it costs you a round.
Mouse TestCheck every button, scroll direction, double-click timing (catches a worn switch that's double-clicking on its own), and movement events per second.
Polling Rate TestMeasure your mouse's real report rate in Hz from the raw coalesced pointer reports -- not the frame-rate-capped number most tests show.
Touch Screen TestDraw on a full-screen canvas to find dead zones, and see how many simultaneous touch points your phone or tablet supports for multi-finger controls.
Monitor
Live frames-per-second counter with a moving bar so you can see stutter as well as read it. Capped by your refresh rate by design.
Refresh Rate TestMeasure the refresh rate your monitor is actually running at -- 60, 120, 144, 240 Hz or otherwise -- and the frame time behind it.
Dead Pixel TestFill the whole screen with solid white, black, red, green, blue, and gray to spot dead, stuck, or hot pixels before the return window closes.
Screen ResolutionSee your monitor's physical resolution, pixel ratio, viewport size, color depth, and orientation, with the CSS-vs-physical pixel difference explained.
Mic, headset & webcam
See your mic's live input level and waveform, then record a short clip and hear what your teammates hear. Audio never leaves your device.
Speaker & Headset TestPlay a tone in the left ear, the right ear, or both, and sweep from low to high frequency to check headphones, headsets, and speakers.
Webcam TestPreview your camera, see its real resolution and frame rate, switch between cameras, and take a local snapshot before you go live.
Frequently Asked Questions
Does anything get recorded or uploaded?
No. Every test runs entirely inside your browser using its built-in device APIs. The mic and webcam tests ask the browser for permission and show you the stream locally; nothing is sent to this site or anywhere else. Close the tab and it's gone.
Can a browser test really tell me anything about gaming hardware?
For most faults, yes. Stick drift, a dead key, a double-clicking mouse switch, a monitor stuck at 60 Hz, a muted mic -- these all show up in the browser exactly as they show up in a game, because the browser reads the same device input. What a browser can't measure is sub-millisecond latency or a game's own settings; for that you need dedicated software.
Do I need to install anything or make an account?
No downloads, no extensions, no sign-up. Open the test, use the device, read the result.
