About DeviceKit
DeviceKit is a free, privacy-first collection of browser-based diagnostic tools. We build tests for screens, keyboards, mice, webcams, microphones, speakers, touchscreens, and game controllers — all running entirely in your browser with no downloads, no signup, and no data collection.
Every tool on DeviceKit uses standard browser APIs to access your hardware. Camera feeds, microphone audio, keyboard input, and controller data are processed locally on your device and never leave your browser. We do not use analytics cookies, tracking pixels, or fingerprinting scripts.
Our tools are built and maintained by engineers who care about hardware quality and user privacy. Whether you are checking a new monitor for dead pixels, testing a mouse for double-click issues, or verifying your webcam before a meeting, DeviceKit gives you accurate results without compromising your data.
