About Us

Gadget Tester is a lightweight web platform for checking your everyday devices right in the browser, with no downloads and no sign‑ups. We build simple, privacy‑friendly tools that give you instant, real‑time feedback.

Right now you can test three things. The Gamepad Tester checks your controller’s buttons, sticks, triggers, and vibration. The Headphone and Speaker Tester verifies your left and right channels and overall balance. The Mic Tester shows a live waveform, your input level, and lets you capture a quick recording.

Everything runs locally in your browser, so your data stays on your device. The focus is a clean, distraction‑free experience that works across Chrome, Edge, and other Chromium browsers on Windows, macOS, and Linux.
