Test mouse buttons and wheel input to diagnose click and scroll issues.

• View left, right, middle, and side button states in real time.
• Track movement, clicks, and double-click events for quick troubleshooting.

Spot unintended double-click behavior by measuring rapid repeat clicks.

• Measure the time gap between consecutive left-clicks.
• Adjust the detection threshold and export results as JSON.

Measure your clicking speed with a timed CPS test.

• Choose a 5, 10, 30, or 60 second test window.
• Review average CPS, peak one-second speed, and exportable results.

Estimate mouse polling rate from pointer movement timing in the browser.

• Estimate effective Hz from median event intervals.
• Inspect jitter with a histogram and export raw samples as JSON.

Check wheel direction, step size, and scroll consistency.

• Monitor vertical and horizontal wheel input together with travel distance.
• Reveal wheel drift, skipped steps, or jumpy scrolling behavior.

Test drag behavior and pointer accuracy with full-page trail capture.

• Draw and replay drag paths to expose drops, stutter, or jitter.
• Review start and end points, speed, and path length for diagnostics.

Test trackpad gestures and touch input with full-page capture.

• Visualize touch trails for single-, double-, and multi-finger input.
• Verify pinch, swipe, and press states when checking driver behavior.

Test key response, rollover, and simultaneous input behavior.

• See pressed keys highlighted on a full keyboard layout.
• Track the latest keydown and keyup events with timestamps.

Detect possible key chatter by flagging unusually fast repeated key presses.

• Review suspected chatter counts for each key.
• Tune the threshold, ignore auto-repeat, and export results as JSON.

Monitor live input levels, permission state, and device changes for your microphone.

• Watch a live RMS level meter with peak tracking.
• Switch input devices quickly and review permission events.

Preview webcams, capture snapshots, and verify negotiated resolution and FPS.

• List available webcams, including virtual devices, in one place.
• Capture local frames to inspect focus, exposure, and color response.

Check display resolution, refresh rate, gradients, and motion clarity.

• Review brightness, contrast, grayscale, and color transitions.
• Use built-in patterns for dead pixels, motion blur, and panel checks.

Use full-screen solid colors to spot dead pixels, stuck pixels, and uniformity issues.

• Switch colors quickly with fullscreen keyboard shortcuts.
• Cycle through common test colors while viewing the current HEX value.

Count characters, words, lines, and UTF-8 bytes in real time.

• Track character counts with or without spaces, plus words, lines, CJK characters, and bytes.
• Use quick clipboard actions to paste text or copy content and stats.
