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.

  1. 01

    Choose a test

    Pick the performance test you want to measure.

  2. 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.

  3. 03

    Read a clear result

    One primary metric, explained in plain language, with what it measures and the factors that can affect it.

  4. 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.
