Keyboard, mouse, touch and gamepad

Every key, button, finger and stick, shown as you press it.

Keyboard TestNewPress every key and see it light up: find dead or stuck keys, check rollover, and see the code and location each key sends.

Mouse TestNewTest every mouse button, the scroll wheel and side buttons, catch a mouse that double-clicks by itself, and estimate its report rate.

Gamepad TestNewTest a game controller in the browser: every button and trigger, both sticks with drift at rest, and vibration — Xbox, PlayStation and more.

Touch Screen TestNewCheck a touch screen: how many fingers it tracks at once, and draw across it to find spots that do not respond.

Screen, camera, microphone and speakers

Resolution and pixel ratio, a camera preview, a level meter and a recording, left and right channels.

Camera TestNewCheck your webcam or phone camera works: a live preview, its resolution and frame rate, every camera to choose from, and a still to save.

Screen ResolutionNewYour screen resolution in device and CSS pixels, the browser viewport, pixel ratio, aspect ratio, refresh rate, colour depth and HDR.

Microphone TestNewCheck your microphone works: a live level meter, a plain verdict (too quiet, good, clipping), and a five-second recording to play back.

Speaker TestNewCheck your speakers or headphones: left and right channels one at a time, test tones from deep bass to treble, and a 20 Hz–20 kHz sweep.

Browser and graphics

What your browser is and supports, its graphics, and how much it may store.

What Is My BrowserNewWhich browser, version, engine and operating system you are using — Windows 11 told apart from 10 — with your user agent, languages and settings.

WebGL and GPU TestNewCheck that WebGL and WebGPU work: a real test drawing, your graphics card’s name, the limits browsers see, and a warning if graphics run in software.

Browser Feature DetectorNewOver seventy web features checked in your browser — graphics, storage, devices, workers, security and CSS — with a report to copy.

Browser Storage TestNewHow much a site may store in your browser, how much this one uses, and whether local storage, IndexedDB, cache and cookies work or are blocked.

Connection, clipboard and system

WebRTC for calls, online and connection type, copy and paste, notifications and battery.

Clipboard TestNewCheck copy and paste work, and see everything on your clipboard — plain text, the hidden HTML formatting, pictures and files — without it leaving your device.

WebRTC TestNewCheck WebRTC works for browser video calls: a real connection made inside the page, the candidates your device offers, and whether your local address is hidden.

Notification TestNewSend yourself one test notification to check browser notifications work, see whether this site is allowed, and find where your system hides them.

Network InformationNewOnline or offline, live, and what your browser estimates about the connection: quality class, rough speed, round trip, type and Data Saver.

Battery InformationNewYour battery level, whether it is charging, and the browser’s estimate of time to full or time left, updated live (Chrome, Edge and other Chromium browsers).
