Browser Information

Check browser family, platform, storage, cookies, JavaScript, WebGL, WebGPU and API support.

Why results may vary

Browser detection is intentionally conservative and avoids aggressive fingerprinting.

How to use this test

Open the page to inspect browser-reported family/version information and capability checks for storage, cookies, WebGL, WebGPU, Gamepad and MediaDevices.

How the measurement works

The page prefers userAgentData brands when available, falls back to conservative user-agent parsing and performs local feature checks without aggressive fingerprinting.

How to interpret results

A Supported result means the API exists in the current browser context; it does not guarantee every device permission or feature will work. Version strings may be reduced by browser privacy policies.

Troubleshooting tips

Update the browser, disable restrictive private modes for comparison and check permissions if MediaDevices or storage features are unavailable.

QUESTIONS & FIXES

Common browser info questions

How do I check my browser version and capabilities?

The Browser Information page combines browser-reported identity data with feature checks for APIs such as media devices, gamepads, storage and graphics. Exact version detail can be reduced by privacy features.

Why does my browser hide or reduce user-agent information?

Modern browsers intentionally reduce some user-agent detail to limit passive fingerprinting. Feature detection is usually more reliable than assuming capabilities from a long user-agent string.

What is the difference between API support and device availability?

An API can be supported by the browser even when the required hardware, permission or secure context is unavailable. For example, MediaDevices support does not guarantee a camera is connected or permitted.

Why can browser version detection be incomplete?

User-agent reduction and privacy features can limit exact version strings. The page prefers browser-reported brand data when available and uses conservative fallbacks.
