Use these mouse diagnostics to separate click, movement, scroll and pointer-timing problems. Each test measures a different browser-visible signal, so combining two or three related checks is more useful than relying on one score.
Keyboard tools cover two different needs: diagnosing whether physical keys reach the browser correctly and measuring how quickly or accurately you type or tap a specific key.
These browser gaming tests focus on human response, input devices and browser rendering. They are designed for repeatable comparisons rather than claims about FPS inside unrelated installed games.
Display diagnostics combine browser-reported screen information with visual inspection patterns. They can help reveal obvious pixel, refresh, scaling and color issues without installing desktop software.
These tools use browser media and audio APIs only after you start a test. They are designed for quick pre-call checks and troubleshooting without intentionally uploading microphone audio or webcam video.
Touchscreen diagnostics listen specifically for touch pointers so a desktop mouse cannot create a false pass. Grid coverage checks response across the panel while multi-touch tracks simultaneous fingers.
System and network tools show only information a browser or the current web request can legitimately expose. The speed test performs real network transfers; device and browser pages avoid pretending they can read hidden hardware details.
