Click Speed Test

Measure CPS, CPM, rank, and timed click challenge results.

Mouse Polling Rate Test

Check mouse Hz, median, peak, distribution, and stability.

Double Click Test

Detect accidental double-clicks, switch chatter, and click gaps.

Mouse Test

Check buttons, scroll wheel, and basic mouse input behavior.

Keyboard Test

Press every key and verify browser-visible keyboard input.

Dead Pixel Test

Inspect your screen with full-screen color patterns.

Choose the right diagnostic path

Hardware problems are easier to narrow down when related tests are grouped by device and signal.

Mouse & Input Tests

Measure clicking speed, polling behavior, accidental double-clicks, and standard mouse input.

Measure CPS with the Click Speed Test

Run 10s, 30s, or 60s click challenges and share the result.

Check mouse Hz with the Mouse Polling Rate Test

Compare median, peak, distribution, and stability against expected Hz.

Diagnose switch chatter with the Double Click Test

Measure click gaps and catch unintended double-click behavior.

Verify buttons and wheel with the Mouse Test

Check left, right, middle, and scroll wheel events in the browser.

Display Tests

Inspect pixels, refresh behavior, uniformity, and motion clarity.

Inspect pixels with the Dead Pixel Test

Use full-screen solid colors to find dead or stuck pixels.

Check monitor Hz with the Refresh Rate Test

Estimate 60Hz, 144Hz, 240Hz, or higher browser-visible refresh timing.

Find backlight issues with the Screen Uniformity Test

Check IPS glow, backlight bleed, and color tinting.

Inspect ghosting with the Response Time Test

Use moving patterns to compare motion blur and overdrive artifacts.

Gaming & Controllers

Check controller input, reaction speed, aim precision, and click accuracy.

Check buttons and sticks with the Controller Test

Inspect triggers, analog sticks, deadzones, and stick drift symptoms.

Measure reflex speed with the Reaction Time Test

Run a timed click reaction test and compare your average result.

Practice target control with Aim Trainer

Click appearing targets and track speed plus accuracy.

Measure precision with the Mouse Accuracy Test

Click fixed targets and compare hits, misses, and accuracy.

Audio & Video

Check speakers, microphones, and cameras before calls, recording, or streaming.

Test speakers with the Sound Test

Play channel, tone, sweep, bass, and noise references.

Check input level with the Microphone Test

Verify browser microphone permission and live signal level.

Preview camera output with the Webcam Test

Check camera permission, resolution, and live video behavior.

How Our Tests Work

Browser-based diagnostics powered by modern web APIs

Browser APIs

Our tests use standard web APIs like Gamepad API, Pointer Events, and Web Audio to read browser-accessible hardware signals. No plugins or downloads are required.

Local Processing

Raw test inputs stay on your device. Test feedback is processed locally in your browser and is not uploaded to our servers.

Instant Results

Get real-time feedback as you test. Our tools visualize inputs immediately so you can quickly identify any issues with your hardware.

What is Online Hardware Testing?

Online hardware testing allows you to verify that your computer peripherals work correctly using browser-based tools. You can check for dead pixels on your monitor, test keyboard key responses, verify mouse clicks and scroll wheels, measure click speed (CPS/CPM), and check gamepad stick drift symptoms without downloading or installing software.

Why Use Browser-Based Hardware Tests?

Traditional hardware diagnostics often require installing software from a device manufacturer. Browser-based checks reduce that friction and work across Windows PCs, Macs, Chromebooks, phones, and tablets where the required browser APIs are supported.

HardwareTest uses standard web APIs such as Pointer Events, KeyboardEvent, Gamepad API, Web Audio, MediaDevices, Canvas, and requestAnimationFrame. These APIs expose browser-visible signals, not privileged driver-level data, so results should be interpreted as practical diagnostics rather than lab certification.

Most test processing runs locally in your browser. Permission-based inputs such as keystrokes, microphone audio, camera video, and controller events are not uploaded as raw test data. Ordinary page requests, aggregate analytics, ads, and network-test requests may still occur.

No Installation Required

Open a tool and start testing in seconds. No downloads, drivers, or browser extensions are required.

Broad Compatibility

Core checks work in modern browsers. API-dependent tools vary by browser, operating system, and device.

Private by Design

Raw keystrokes, microphone audio, camera video, and controller inputs stay in your browser.
