TestYourBrowser
Free on-device tests for browser features and screen hardware
About TestYourBrowser
TestYourBrowser is a free utility site for people who want to know whether their browser and hardware can handle modern web features. It is aimed at anyone checking a monitor for dead pixels, testing speakers or a touch screen, confirming video playback support, or preparing a camera and microphone before a call.
The site offers a range of checks covering screen quality, frame rate and refresh rate, WebGL graphics, DPI, stereo sound, WebRTC call quality, HEVC and video codec support, notifications, cookies and storage, and ad blocker behavior. Each test runs locally in the browser, so no downloads are needed and the site does not scan the computer or read files.
What sets it apart is the focus on on-device diagnostics with no fingerprinting, plus step-by-step troubleshooting guides for Chrome, Firefox, Safari and Edge when a feature is not working.
