I use gamepadtest.tech to check controllers online. They also offer a GPU tester, mic tester, and MIDI tester on the same site — great for quick troubleshooting.

A lot of gamers and creators run into the same problem — something stops working mid-game or mid-recording, and you don't know if it's a software bug or a hardware issue.

That's why I built GamepadTest and other free tools to make the process simple.

Controller Tester: Works with PS4, PS5, Xbox, and PC controllers. It shows every button press, joystick movement, and can even detect stick drift in real time.

GPU Tester: Lets you run a quick benchmark online to check performance, monitor temperature, and spot stability issues without installing anything.

Mic Tester: Great for checking your microphone before a stream, call, or recording session. It gives instant feedback so you know your voice is being picked up.

MIDI Tester: Perfect for music producers to verify keyboard and pad inputs when troubleshooting DAW connection problems.

All tools run directly in the browser — no downloads, no setup. They're quick, free, and designed for anyone who just wants to know if their gear is working.
