About

A tester that respects you

Free Gamepad Tester is a free online diagnostic for game controllers. It reads your pad through the standard browser Gamepad API and visualizes every button, stick, trigger and rumble motor, with drift analysis, polling stats, circularity checks and a 0 to 100 health score.

Everything runs locally on your device. There is no account, no upload and no download. Diagnostics you export are generated in-browser and downloaded only when you ask.

Why it exists

Existing testers either show raw numbers without verdicts, split tools across confusing pages, or demand software installs. We built one page that answers the real question (is my controller healthy?) with verdicts, history and shareable proof for buyers, sellers and repair shops.
