I built InputBench, a free browser-based site for testing common mouse and keyboard problems.

Most online input tests show raw events or simple counters. I wanted something more useful for normal troubleshooting: do the simple action first, then get a plain-language explanation of what the browser actually received. Current tools include: Scroll Test: checks mouse wheel direction, reverse scroll signals, sensitivity, and stability Mouse Test: checks left, right, middle, back, forward, and wheel input Double Click Test: checks whether one physical click may be registering as repeated trig
