About TechTest
Making advanced hardware diagnostics accessible, free, and incredibly simple.
Our Mission
TechTest was built on a simple premise: you shouldn't have to download sketchy software, pay exorbitant fees, or navigate a minefield of ads just to figure out if a key on your keyboard is broken, or if your controller has stick drift.
By leveraging the latest in Web APIs (like the Gamepad API and WebHID), we bring powerful hardware diagnostics directly into your browser. It runs locally on your device, meaning it is fast, secure, and privacy-respecting.
Privacy First
We don't want your data. All of our diagnostic tests run entirely locally in your browser. We don't record your microphone, we don't save your webcam feed, and we don't log your keystrokes. Once you close the tab, the diagnostic data is gone forever.
