All Testing Tools
Pick a tool to diagnose screens, input devices, audio gear, and controllers.
Dead Pixel Tester
Test your monitor for dead pixels, stuck pixels, and screen uniformity with our professional color testing tool.
Mouse Polling Rate Test
Measure mouse polling rate (browser event Hz) with distribution, median, peak, and stability checks.
Click Speed Test (CPS/CPM)

Gamepad Tester
Test your controller buttons and analog sticks, and check for stick drift with an adjustable deadzone.
Keyboard Tester
Test every key on your keyboard to ensure all keys are working properly. Perfect for checking new or used keyboards.
Mouse Tester
Test left/right clicks and scroll wheel directions with instant visual feedback and scoring.
Audio Tester
Test your speakers, headphones, and microphone. Check left/right channels, frequency response, and audio quality.
Refresh Rate Test
Verify your monitor's actual refresh rate — 60, 144, 240 Hz or higher — using browser frame timing. No downloads required.
Camera Tester
Test your webcam or camera. Check resolution, frame rate, color accuracy, and focus quality.
Screen Uniformity Test
Check your monitor for backlight bleeding, IPS glow, and uneven brightness with full-screen solid color tests.
Response Time Test
Visualize monitor ghosting and motion blur with animated UFO, pursuit, and contrast test patterns.
Color Gradient Test
Test your monitor for color banding and bit depth issues using smooth gradient and stepped color patterns.
Brightness & Contrast Test
Calibrate your monitor brightness and contrast using ANSI, PLUGE, and near-black/white test patterns.
Screen Burn-In Test
Detect OLED and LCD screen burn-in and image retention using solid colors and cycling patterns.
Reaction Time Test
Measure your reflex speed in milliseconds with a 5-round click test. Compare to gamer and average population benchmarks.
FPS Test
Measure your browser's actual frame rate over 10 seconds using requestAnimationFrame. See average, min, and max FPS with a live bar chart.
Aim Trainer
Click targets to train mouse accuracy and measure targets per second. Three difficulty levels: large, medium, and small targets.
Mouse Accuracy Test
Precision click test — click stationary targets and measure your accuracy percentage and click speed across difficulty levels.
Typing Speed Test
Measure your typing speed in words per minute (WPM) and accuracy. Choose 30s or 60s mode with color-coded word feedback.
Key Rollover Test
Test keyboard anti-ghosting and N-key rollover (NKRO) by pressing multiple keys simultaneously and seeing which register.
Input Lag Test
Measure browser-level click-to-frame latency using requestAnimationFrame. See average, best, and worst lag across 10 clicks.
Microphone Test
Test your microphone in the browser. Check volume level, peak meter, and waveform visualization using getUserMedia.
Hearing Test
Check your hearing range across 8 frequencies from 125 Hz to 16000 Hz. Identify which frequencies you can and cannot hear.
Bass Test
Test your subwoofer and speakers with low-frequency tones from 20 Hz to 200 Hz. Find the lowest bass your system can reproduce.
Headphone Test
Test headphone channel balance, frequency sweep, and phase response. Verify left/right audio and stereo imaging.
Speaker Channel Test
Test individual speaker channels including left, right, center, and surround. Verify each speaker in a multi-channel setup.
Xbox Controller Test
Test Xbox controller buttons, analog sticks, triggers, and D-pad in your browser. Detect stick drift with adjustable deadzone.
Switch Controller Test
Test Nintendo Switch Pro Controller and Joy-Con buttons, sticks, and triggers in your browser. Detect Joy-Con drift.
Mouse DPI Test
Calculate your mouse's actual DPI by moving it a measured distance. Verify if your mouse matches its rated specification.
Double Click Test
Test your mouse double-click speed. Measure the gap between clicks and check if they register as double-clicks.
Scroll Speed Test
Test your mouse scroll wheel speed and behavior. Measure deltaY values, scroll direction, and events per second.
Touchscreen Test
Test multi-touch support on your touchscreen device. Check how many simultaneous touch points your screen supports.
Stylus & Pen Test
Test stylus pen pressure, tilt, and drawing on canvas using the Pointer Events API. Works with Wacom, Apple Pencil, and Surface Pen.
Color Blind Test
Simplified Ishihara-style color vision screening. Check for red-green and blue-yellow color vision deficiency using 8 colored dot plates.
HDR Monitor Test
Test HDR display performance: peak brightness, shadow detail, contrast ratio, and color volume using Canvas-rendered test patterns.
Pixel Refresh Tool
Attempt to fix stuck pixels by rapidly cycling through 8 colors. Adjustable speed from 50ms to 500ms with fullscreen support.
Black Level Test
Check monitor shadow detail with near-black patches from value 1 to 30 and a PLUGE calibration pattern. Normal and inverted modes.
White Point Test
Compare white patches at 5000K, 5500K, 6500K (D65), 7500K, and 9300K. Side-by-side comparison mode and gray ramp.
Aspect Ratio Test
Verify monitor geometry with circle test, grid, diagonals, crosshair, and ruler patterns. Detects display resolution and closest aspect ratio.
Screen Resolution Checker
Instantly display screen resolution, available resolution, device pixel ratio, physical pixels, color depth, and orientation.
Monitor Flicker Test
Detect PWM backlight flickering with frequency patterns from 30 to 1000 Hz. Includes motion ruler mode and strobe mode.
Network Latency Test
Measure your browser-to-server round-trip latency with 10 pings. See average, min, and max response time in milliseconds.
Browser Benchmark
Benchmark your browser with Math, DOM, String, and Array performance tests. Compare your browser speed score.
GPU Stress Test
Stress test your GPU with a heavy Canvas animation of 500 moving circles. Monitor live FPS under load.
CPU Benchmark
Benchmark CPU performance with 5 JavaScript tests: integer math, float math, prime sieve, Fibonacci, and JSON parsing.
RAM Checker
Check browser memory usage and device RAM. View JS heap size, device memory, and run an allocation speed test.
