PeriphCheck
Test any device in your browser — free, instant, private
An all-in-one testing suite for your hardware: keyboard, mouse, controller drift, mic, webcam, dead pixels, refresh rate and more. 100% client-side — no downloads, no sign-up, and nothing you do ever leaves your device. Free forever.
Hey Product Hunt! 👋
I built PeriphCheck because testing your own hardware shouldn't require downloading sketchy software or wondering where your webcam feed goes.
It's 15 tools in one place: keyboard tester (with key chatter + NKRO detection), a 10-second controller drift test, mouse double-click bug detector, mic/webcam checks, dead pixel test, real refresh rate detection, and more.
The whole thing is 100% client-side — there is literally no backend. Your keystrokes, audio and video are processed in your browser's memory and never uploaded. It's also fast (every page under 50KB of JS) and works on mobile.
My favorite detail: the controller drift test gives you an actual deviation percentage, so you know if your stick is fine (<2%), fixable (2–5%), or needs a new module (10%+).
Would love your feedback — especially if a tool misreads your hardware, tell me the model and I'll fix the mapping. Everything is free, no strings.
