Browser Capability Test – Camera, Audio, Sensors & APIs

Checking capabilities…

Direct answer

What is the Browser Capability Test – Camera, Audio, Sensors & More?

Check whether your browser supports camera, microphone, audio, fullscreen, touch, sensors, location, storage, WebGL, WebGPU and other device-testing APIs.

✓ No installation✓ Works in compatible browsers✓ Privacy-focused testing

Why support varies

Features depend on browser version, operating system, HTTPS, user permission and device hardware. An unavailable API does not necessarily mean the hardware is missing.

Practical guide

What does the browser capability test tell you?

Modern websites can access hardware only through browser APIs, and support varies by browser, operating system and security policy. This page checks whether those interfaces are exposed before you spend time troubleshooting a camera, sensor or other device feature.

For a more reliable result

A supported API means the browser knows how to request that feature; it does not prove that matching hardware is installed.
Camera, microphone, location and sensor access can still fail if permission is denied or the operating system blocks access.
Some capabilities, such as Bluetooth, USB, motion sensors or WebGPU, may be limited to certain browsers or secure HTTPS pages.
Use the result together with the dedicated tester for the hardware you actually want to check.

What this test cannot confirm

A result marked unsupported is about the current browser context, not necessarily the physical device. Trying another browser or checking system permissions may change the result.
