What Is Browser Feature Detection?
This tool checks your browser's genuine, live support for a wide range of modern web technologies - from graphics APIs like WebGL to hardware access APIs like the Gamepad API and Battery API. Each entry runs an actual check against your browser right now (checking whether a specific object, method, or CSS capability genuinely exists), rather than relying on a static compatibility chart that could be outdated or wrong for your exact browser version.
How to Use Browser Feature Detection
- Load this page - every check runs automatically the instant it loads.
- Scroll through the grid to see which specific technologies your browser supports.
- Check the summary counts at the top for a quick overall picture.
- Use this as a reference when troubleshooting why a specific tool or website feature isn't working as expected.
How It Works
For each listed feature, this tool runs a small, direct JavaScript check - for example, testing whether
navigator.getGamepads exists as a function, whether WebAssembly is defined
globally, or whether a canvas element can successfully create a WebGL rendering context. Each check reflects
exactly what your specific browser, version, and current settings actually expose right now - nothing is
inferred from your browser's name or version number, only from directly testing for the feature itself.
Understanding Your Results
- Most modern features show "YES" - you're using an up-to-date, fully-featured browser, which is the expected result for most current browser versions.
- A specific niche API shows "NO" - some features listed here, like the Barcode Detector API or Keyboard Layout Map API, are currently limited to Chromium-based browsers and are expected to show "NO" in Firefox or Safari.
- Many features unexpectedly show "NO" on an otherwise modern browser - could indicate a specific browser setting, extension, or enterprise policy is disabling certain capabilities; worth checking your browser's feature flags or admin-managed settings if you expected broader support.
- CSS feature checks fail unexpectedly - these use the standard
CSS.supports()method, which is itself widely supported, so a "NO" here genuinely reflects that specific CSS capability being unavailable.
Browser Limitations
Feature support varies meaningfully across browsers and versions by design - browser vendors implement new web standards at different paces, and some features remain intentionally experimental or browser-specific for extended periods before wider adoption. This tool reports your browser's actual current state honestly; a "NO" result doesn't necessarily mean a feature will never be supported, just that it isn't right now, in this specific browser and version.
Common Mistakes to Avoid
- Assuming a "NO" result means your browser is outdated - many listed features are genuinely still limited to specific browser engines regardless of how current your browser version is.
- Expecting identical results across different browsers - feature support intentionally differs between Chrome, Firefox, Safari, and Edge, even at their most current versions.
- Not checking browser settings when a common feature shows "NO" - some features can be disabled by user preference, enterprise policy, or a privacy-focused browser configuration.
Frequently Asked Questions
Why do results differ between my phone and my desktop browser?
Mobile and desktop versions of the same browser can have different feature support, and mobile operating systems sometimes restrict certain APIs differently than desktop platforms.
Does a "NO" result mean my browser has a bug?
No, it simply means that specific feature isn't currently implemented or exposed in your browser - many listed features remain intentionally limited to certain browser engines by design.
Is any of this data sent anywhere?
No. All checks run and display results entirely within your browser and nothing is transmitted or stored.
Why should I care whether a feature is supported?
If a specific tool or website feature isn't working, checking whether the underlying API is supported here can quickly clarify whether it's a browser limitation rather than something else being wrong.
Will these results change if I update my browser?
Potentially, yes - browser updates regularly add support for new features, so re-running this check after an update can reveal newly available capabilities.
Conclusion
This gives you a genuine, comprehensive snapshot of exactly what your browser can do right now, checked directly rather than assumed from its name or version. For a broader look at your browser's identity and basic details, pair this with Browser Information & User Agent.
