What browser am I using?

Your browser is the app opening this page—Chrome, Edge, Firefox, Safari, and others. This page shows the name and version immediately, plus your operating system, device type, screen size, and viewport.
People search “what is my browser” for a practical reason: support asked, a site said the browser is outdated, or the About menu is hard to find on a phone. The card at the top of this page is the answer—product name, version, OS, and device—read from the same JavaScript APIs websites already use.
How detection works: the page reads navigator.userAgent (and User-Agent Client Hints on Chromium when available), window.screen, window.innerWidth/innerHeight, language, timezone, and capability checks (storage, WebGL, WebRTC, and similar). On reduced user-agent strings, Client Hints often provide a fuller version. Nothing is uploaded to EverydayTools.
What websites can detect is largely what you see here. They usually cannot read your public IP from these client APIs alone—IP requires a server response. Values can be wrong if an extension spoofs the user agent, if you are inside an in-app WebView, or if the browser withholds optional fields (memory, network) for privacy.
Browser vs operating system: the browser is the app (Chrome); the OS is the platform (Windows 11, macOS, Android, iOS). Screen size is the display; viewport size is the layout area CSS uses inside the browser chrome. Device pixel ratio maps CSS pixels to physical pixels—often 2 or 3 on phones.
For pasting an arbitrary user-agent string from logs, use the User-Agent Parser. For breakpoint-focused layout QA, use the Screen Resolution Checker. This page does not show your public IP address.

Screen size is the display. Viewport size is the layout area inside the browser window—the width CSS media queries typically use. For breakpoint-focused checks, use Screen Resolution Checker.

Common real-world scenarios where this tool saves time.
Confirm name and version when a site says you are outdated or a friend asks which browser you opened.
Send a copyable environment snapshot—user agent, OS, viewport, and capability flags—without a screen share.
Verify screen vs viewport, DPR, and orientation on a real device before filing layout bugs.
Inspect cookies, storage, WebGL/WebRTC, and network effectiveType when diagnosing feature failures.
Step-by-step chains that connect related tools for common tasks.
Avoid overlapping tools—pick by intent.
| You need | Use |
|---|---|
| “What browser am I using?” right now | Browser Info (this page) |
| Parse any pasted user-agent string | User-Agent Parser |
| Live viewport + CSS breakpoint focus | Screen Resolution Checker |
| Public IP address | Not on EverydayTools yet—do not use this page |
Client-side browser APIs do not reveal your public IP. EverydayTools does not display IP on this page.
UA switchers change the string sites see. Prefer the browser’s About page if the version looks wrong, then Refresh.
Layouts use viewport (innerWidth/innerHeight). Screen describes the display; they often differ on desktop.
Likely cause: UA spoofing, reduced UA strings, or an embedded WebView.
Fix: Check Help → About, disable UA switchers, then Refresh this page.
Likely cause: Optional APIs withheld for privacy or unsupported in that browser.
Fix: Treat them as unavailable—common for device memory and network details.

Look at the top card on this page. It shows your browser name (for example Chrome or Safari) and version as soon as the page loads, plus your operating system and device type.
The version line under the browser name is what this checker detected. On Chromium browsers we also try User-Agent Client Hints for a fuller version. You can confirm anytime in the browser’s About page.
The Operating system field reports the platform from the user agent and, when available, Client Hints (helpful for distinguishing Windows 10 vs 11 on Chromium).
The Device field classifies desktop, mobile, or tablet from the user agent and Client Hints mobile flag when present. It is a best-effort label, not a hardware model name.
Your live user agent string is shown in the result card (and under Technical details → Browser). Use Copy user agent to paste it. To parse any pasted UA string from logs, use the User-Agent Parser—not this page.
Screen width/height describe the display. Viewport width/height are the layout area inside the browser chrome—what CSS media queries usually use. For a dedicated screen/viewport/breakpoint tool, use Screen Resolution Checker.
Device pixel ratio (DPR) is physical pixels divided by CSS pixels. A DPR of 2 or 3 on phones means one CSS pixel maps to multiple device pixels—important for sharp images and retina layouts.
This page reads standard browser APIs in your tab: the user agent string, optional Client Hints, screen and viewport metrics, language, timezone, and feature probes (for example WebGL or localStorage). It does not install software or scan your disk.
Sites can typically read user agent or Client Hints, language, timezone, screen/viewport metrics, and many capability flags—the same class of signals shown here. Public IP requires a server-side lookup and is not shown on this page.
Extensions can spoof the user agent, privacy modes reduce detail, in-app browsers (WebViews) look different from standalone Chrome or Safari, and optional APIs may be unavailable. When unsure, compare with Help → About in your browser.
This page shows the version your browser reports. It does not maintain a live “latest release” database. Open your browser’s About page to check for updates and security patches—that is the most reliable source.
No. Detection runs in your browser. Optional recent snapshots stay in local storage on this device only and are never uploaded to EverydayTools.
Yes. Open the page in the mobile browser to see real viewport size, DPR, touch support, and orientation for that device.
It reports environment and capability flags (storage, WebGL, WebRTC, and similar). It is not a full cross-browser compatibility suite or automated site test runner.
Environment data is read in your browser from standard APIs. Nothing is uploaded to EverydayTools.
Values reflect what your browser exposes right now, including optional Client Hints. Spoofing and privacy modes can change results.
Point-in-time snapshot. Not a security audit, fingerprinting lab, IP geolocation tool, or live “outdated browser” database. Refresh after viewport or settings changes.
