Browser-based performance testing
Test your device.
Test yourself.
Testpartout is a browser-based testing platform for the way you use your hardware every day. Measure your reaction time, typing speed, clicking rate, visual memory, sequence memory and aiming accuracy — all in one place.
Nothing to install, no account, and a documented method behind every number.
Live tests
Six performance tests you can run now
Each test isolates one ability, records every attempt, and reports a metric you can repeat tomorrow under the same conditions.
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.
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 flow is the same whether you are measuring your reflexes or checking your typing speed.
- 01
Choose a test
Pick the performance test you want to measure.
- 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
Read a clear result
One primary metric, explained in plain language, with what it measures and the factors that can affect it.
- 04
Beat your own personal best
Each test keeps your best result in this browser, on your device — a personal best, not an account history.
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.
