What Is My Browser

About This Tool

So, you’re wondering what browser you’re using right now? Maybe you clicked a link and it opened in something weird. Or maybe you’re troubleshooting a site that’s acting up and someone asked, “What browser are you on?” That’s where “What Is My Browser” comes in. It’s a simple, no-nonsense tool that tells you exactly which browser you’re running—along with a few other details that might actually matter. No sign-up. No tracking (well, not by the tool itself). Just instant info. I’ve used it more times than I’d like to admit. Mostly when a client says, “It works on my end,” and I need proof it’s not just their ancient Firefox setup from 2012. It’s not flashy. But it gets the job done.

Key Features

• Instant browser detection – Tells you the name, version, and sometimes even the rendering engine (like Blink or WebKit).
• Operating system info – Shows whether you’re on Windows, macOS, Linux, or mobile.
• Device type – Lets you know if you’re on a desktop, tablet, or phone.
• User agent string – The full technical string browsers send to websites. Useful if you’re debugging or pretending to be a developer.
• No installation needed – Just visit the site. Works in any browser, even the ones you forgot you had.
• Privacy-friendly – Doesn’t store your data. At least, not unless the site you’re using is sketchy (so maybe avoid the knockoff versions).

FAQ

Why would I need to know my browser?
Honestly? Most people don’t. But if a website looks broken, or a form won’t submit, support teams will ask. Knowing your browser helps them figure out if it’s a compatibility issue. Also, some sites block older browsers—so if you’re stuck on IE11 (why?), you’ll know why nothing loads.

Does this tool work on mobile?
Yep. Open it on your phone or tablet, and it’ll detect your mobile browser—whether it’s Safari on iOS, Chrome on Android, or that weird browser your cousin installed from a pop-up ad. It even shows if you’re using a built-in browser from an app like Facebook or Twitter.
