Browser-based device & performance testing
Test your device.
Test yourself.
Testpartout brings device diagnostics and human-performance tests together in your browser. Check your hardware, or measure reaction time, typing, clicking, memory and aiming accuracy — with no installation required.
Nothing to install, no account, and a documented method behind every number.
Check the whole setup
Work through related checks with a local checklist, without an account or a hardware-health score.
Full Device Check →
Display, input, camera and audio checks in order. A used-laptop preset adds clearly labeled manual inspections.
Video Call Check →
Check webcam, microphone and sound before a meeting. Device selection in the calling app still matters.
Live tests
Browser tests you can run now
Run browser-based checks and performance tests with clear results, documented methods and honest limitations.
Device diagnostics
Test your device
Check the hardware and input devices your browser can inspect.
Audio
Microphone Test
Check that your microphone is detected and picking up sound, with a live input level meter.
Speaker Test
Play left, right and reference tones to check each speaker is working, on the correct side and free of obvious distortion.
Left / Right Headphone Test
Verify stereo channels, wiring and balance by playing audio to the left and right sides separately.
Camera
Webcam Test
See your camera feed, confirm the right device is selected and check framing before a call.
Input Devices
Touch Screen Test
Map touch coverage, compare simultaneous contacts and watch for unexpected touch events reported by your browser.
Keyboard Ghosting & Key Rollover Test
Hold combinations together and compare browser-observed keys, presets and maximum simultaneous input.
Mouse Polling Rate Test
Estimate browser-delivered mouse event rate over ten seconds with median intervals and sample context.
Keyboard Test
Press keys to confirm every one registers, and find stuck, dead or repeating keys.
Mouse Test
Check buttons, double-clicks, scrolling and pointer movement for a failing or erratic mouse.
Gamepad / Controller Test
Check buttons, triggers and analog sticks, including stick drift and dead-zone behaviour.
Display
Monitor Test
Inspect manually selected colors, gradients, uniformity and geometry patterns without automatic defect claims.
Dead Pixel Test
Run full-screen solid colours to reveal dead, stuck or discoloured pixels on your display.
Screen Resolution Test
See the resolution, viewport size, pixel ratio and colour depth your browser reports.
Refresh Rate Test
Estimate the refresh rate your display is actually running at, with the limits of the method stated.
Human performance
Test yourself
Measure reaction, speed, memory and accuracy with repeatable browser-based tests.
Reaction Time Test
Measure how fast you respond to a visual cue, in milliseconds, across repeated attempts.
Typing Speed Test
Words per minute, accuracy and mistake patterns over a timed typing passage.
Click Speed Test
Clicks per second over a fixed interval, with consistency across attempts.
Visual Memory Test
Recall increasingly complex patterns to measure your visual memory span.
Sequence Memory Test
Repeat growing sequences to find the longest order you can hold and recall.
Aim / Accuracy Test
Hit targets under time pressure to measure accuracy, hits, misses and time-to-target.

Guides & troubleshooting
Understand device symptoms and the methods behind your performance results.
Touch Screen Not Working? Test Dead Zones and Ghost Touch
Troubleshoot missed taps, edge problems, multi-touch and unwanted touch events with slow coverage mapping, safe cleaning and clear browser limitations.
Keyboard Ghosting, NKRO and Key Rollover Explained
Understand blocking, phantom input, 6KRO and NKRO. Test simultaneous gaming combinations with accurate browser-observation limits and reserved-shortcut context.
Monitor Stuck at 60Hz? How to Check Your Refresh Rate
Check OS refresh settings, cable and port limits, power modes, multiple monitors and VRR. Understand why a browser estimate can differ from display output.
Why Is My Microphone Not Working? Troubleshooting Guide
Troubleshoot a silent microphone: browser and OS permissions, input selection, mute, USB and Bluetooth, with a local mic check and clear limits.
Why Is My Webcam Not Working? Camera Troubleshooting Guide
Troubleshoot webcam permissions, a black preview, wrong camera selection and busy devices. Test your camera locally without recording or uploading video.
Keyboard Keys Not Working? How to Test and Troubleshoot Them
Check missing, repeating or stuck keyboard keys with browser events. Compare layouts, shortcuts, USB and Bluetooth before assuming a hardware fault.
Why Testpartout
Built to be trusted, not just used once
A testing tool is only worth anything if you can believe the number it gives you.
Browser-based
Every test runs on the page you are already on. No downloads, no extensions, no accounts required.
Privacy-first
Every test runs entirely in your browser and sends no result to any backend — your personal bests stay on this device.
Real measurements
Timing, input events and hardware capabilities are measured directly — not simulated, not estimated from a quiz.
Honest results
Where a measurement has limits, we say so. No invented benchmarks, no scores we cannot justify.
How it works
Four steps, every test
The same clear flow applies whether you are checking hardware or measuring your own performance.
- 01
Choose a test
Choose the browser check or performance test you want to run.
- 02
Run it in your browser
The test records only the input events it needs for the measurement and stops as soon as you leave the page.
- 03
See a clear result
See what the browser detected or measured, presented clearly without unsupported claims.
- 04
Understand the result
See what the result means, what can affect it, and the limits of what a browser can measure.
Methodology & trust
What we measure, and what we refuse to claim
Transparent methodology. Every test page states what is being measured, how, and the accuracy limits of doing it in a browser. Where a measurement is an estimate rather than an exact reading, it is labelled as one.
Local processing. Input data is handled in the page and discarded when you leave. Personal bests are stored on your own device.
No fabricated scores. Percentiles and global comparisons are hidden entirely until real aggregated results exist. You will not see a made-up “faster than 74% of users” badge on Testpartout.
