I build free browser-based tools that solve real problems for everyday users.

My main project is Pro Gamepad Tester, a 100% free online gamepad tester that works with PS5, PS4, PS3, Xbox, and Nintendo controllers. No download. No account. No installation.

Connect any controller, press one button, and instantly see live readings for every thumbstick axis, trigger value, and button input directly in your browser.

Gamers use it to detect stick drift early, test trigger health, confirm button reliability, and verify repairs before reassembling a controller.
