Browser-based diagnostics for computer hardware and peripherals

Mouse & Trackpad

Mouse Check

Mouse test hub for clicks, wheel input, drag stability, and double-click diagnostics.

  • Start with button and side-click checks, then branch into wheel, drag, and double-click tools.
  • Use focused follow-up pages for jumpy wheels, dropped drags, and repeat clicks.

Trackpad Drag Test

Test whether trackpad press-and-drag stays stable without dropped holds or broken trails.

  • Split plain movement from true press-and-drag to isolate drag-only failures.
  • Use the same canvas model as the mouse drag page for easier comparison.

Double-Click Check

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.

Click Speed Test

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.

Polling Rate

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.

Scroll Check

Scroll wheel test for direction, skipped steps, reverse scrolling, and jumpy wheel behavior.

  • Check scroll up, scroll down, and fast flicks without moving the page itself.
  • Spot reversed direction, skipped notches, or unstable wheel response.

Mouse Drag Check

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.

Trackpad Check

Check movement, drag, scroll, zoom, and secondary click behavior from one browser page.

  • Separate pointer movement from press-and-drag, scroll, and zoom signals.
  • Compare browser-visible trackpad behavior before changing drivers or settings.

Touch Screen Check

Test touchscreen and stylus input in your browser. Visualize multiple contacts, pressure, continuous trails, screen coverage, edges, and corners.

  • Touch + Pen + Multi-touch
  • Coverage map and corners

Keyboard

Keyboard Check

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.

Chatter Check

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.

Audio & Video

Microphone Check

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.

Speaker Check

Play stereo tones, isolate left and right channels, and confirm audio output routing.

  • Test stereo, left-only, and right-only playback directly in the browser.
  • Adjust frequency and volume while checking headphones, speakers, and docks.

Camera Check

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.

Display

Display Check

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.

Dead Pixel Test

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.

Utilities

Word Count

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.

Hidden Watermark Checker

Inspect local image metadata, alpha transparency, and common invisible watermark clues before sharing.

  • Review EXIF or PNG text fields, GPS hints, software tags, and alpha transparency in one pass.
  • Compare RGB channel previews locally without uploading the image to a server.

Controllers

Gamepad Check

Test game controllers in your browser. Check every button, analog stick, trigger, axis value, mapping, connection event, and possible stick drift in real time.

  • Buttons + Triggers
  • Axis detail
