About ToolCheckup.
ToolCheckup is a free hub of browser-based hardware testing tools. It gathers a set of quick, privacy-first device checks in one place so you don't have to hunt across ad-heavy sites when something needs verifying.
The idea
Every hardware test you occasionally need — screen, speakers, printer, mouse, webcam, controller, touchpad, network — lives here under one roof. Each tool runs entirely in your browser, loads instantly, and is completely free. Pick the device, run the check, move on.
Privacy
The tests run locally using standard web APIs. Nothing is uploaded, no account is required, and your microphone, screen and files never leave your device. No tracking beyond basic, privacy-respecting analytics.
The tools

Webcam Test
Check your camera live — resolution, FPS, mirror, snapshot and webcam+mic.
Gamepad Tester
Test any controller — buttons, analog sticks, triggers, vibration and stick drift.
Touchpad Test
