How to use the Device Lab
- Start with the capability scan below to see which device APIs this browser supports.
- Pick a tool group for your situation: the video call kit before meetings, display and input tools when buying or returning hardware, classroom and colour tools for kids.
- Tools that need a permission only ask after you click Start, and you can stop or revoke access in browser settings at any time.
- Each tool suggests a next step, so you can run a complete device check in a few minutes.
Why test devices in the browser
Browsers expose standard APIs such as getUserMedia (camera and microphone), Web Audio (sound analysis and playback), Gamepad, Pointer and Touch events, DeviceOrientation and Geolocation. They read hardware data locally without drivers or apps, which makes them ideal for a quick pre-meeting check, inspecting hardware on delivery, or helping a customer troubleshoot remotely.
Privacy and permissions
Every Device Lab tool computes results in your browser. Audio and video are never recorded to a server or uploaded, and GPS coordinates are not sent to a map service unless you click a map link. Camera, microphone, location and motion sensors require your explicit click and the browser permission prompt; closing the page or pressing Stop releases the device.
Limits of web-based results
A web page only sees what the browser and operating system report: microphone decibels are uncalibrated estimates, refresh rate is inferred from frame timing, GPS accuracy depends on the device and surroundings, and health tools are screening and estimation aids, not medical diagnoses. Use calibrated professional instruments when you need measurement-grade results.
Frequently asked questions
Do I need to install anything?
No. Every tool is a web page that works in current versions of Chrome, Edge, Firefox and Safari on both desktop and mobile.
Is my camera or microphone data uploaded?
No. Video and audio are processed only in browser memory for live preview and level calculation. Recordings and snapshots stay on your device and disappear when you close the page.
Why do some tools not work on iPhone?
iOS Safari restricts some APIs: motion sensors need an extra permission tap, and Gamepad or Battery support is limited. Each tool detects unsupported features and explains the alternative.
Why is my IP location different from my GPS position?
IP location is the approximate position of your network exit, which may be an ISP data centre or a proxy. GPS coordinates come from the device itself. Use IP Check and GPS Coordinates for each purpose.
Can the health tools diagnose anything?
No. The colour vision, hearing, reaction time and BMI tools are screening and estimation aids influenced by your screen, headphones and environment. Consult a doctor or qualified professional with any concerns.
