What is What Is My Browser?

This tool detects and displays your web browser — its name (Chrome, Firefox, Safari, Edge), version number, rendering engine, and the platform it's running on — read from the information your browser reports to every website. It answers "what browser am I using?" and the version details that troubleshooting and support often require.

You'd be surprised how often the answer matters: support teams ask for it, compatibility issues depend on it, and "what version am I on?" is genuinely hard to find in browser menus. This surfaces it instantly.

About the What Is My Browser

Open the page and read your browser details immediately — no input needed.

When it's useful: tech support — support agents routinely ask "what browser and version?" to diagnose issues, and it's faster to read here than dig through browser menus; compatibility troubleshooting — when a site or feature misbehaves, knowing your exact browser/version helps identify whether it's a known compatibility issue; checking you're up to date — old browser versions have security holes and break modern sites, so verifying your version (and updating if it's behind) matters; and web development — confirming which browser you're testing in.

How it works: your browser sends a "user agent" string and other signals to every site, declaring what it is — this tool reads and interprets that. (Note the user agent can be spoofed and is somewhat imprecise by design, but for normal use it accurately identifies your browser.) A security reminder this surfaces: websites can see this information about you (browser, version, platform) automatically — it's part of normal web browsing, one small piece of the "fingerprint" sites can build. Our related tools show What Is My User Agent (the raw string), What Is My Screen Resolution, and What Is My IP Address for the full picture of what sites can detect.

Frequently Asked Questions

Your browser sends a "user agent" string and other signals to every website it visits, declaring what it is — this tool reads and interprets that information. It's the same data every site you visit automatically receives.

Support teams ask for it to diagnose issues, compatibility problems depend on it, and checking you're up to date matters for security. It's genuinely hard to find in browser menus, so a quick readout helps.

Yes — browser, version, platform, screen size and more are sent automatically as part of normal browsing. It's used for legitimate purposes (serving the right version of a site) but also contributes to "fingerprinting" that can track you.

Definitely — outdated browsers have unpatched security vulnerabilities and break on modern sites. If this tool shows you're several versions behind, update. Most browsers auto-update, but it can lag; checking occasionally is wise.

Sometimes — the user agent can be spoofed (deliberately changed) and is imprecise by design (browsers sometimes mimic others for compatibility). For normal use it's accurate; edge cases and privacy tools can alter what's reported.
