## What this tool shows you

This tool instantly detects and displays your browser's full User Agent string, then parses it to extract:

- **Browser name and version** — Chrome, Firefox, Safari, Edge, and more
- **Operating system and version** — Windows, macOS, Linux, iOS, Android
- **Device type** — Desktop, Mobile, or Tablet
- **Rendering engine** — Blink, WebKit, Gecko, or Trident
- **Additional browser properties** — language, platform, screen resolution, cookies status, and hardware details

## Who should use this

- **Web developers**: Debug browser-specific rendering issues by confirming your exact browser and OS version
- **QA testers**: Document the precise environment when filing bug reports
- **Support teams**: Ask users to share their UA string to quickly diagnose compatibility problems
- **Privacy-conscious users**: See exactly what information your browser reveals to websites

## How to use

1. Open this page — your User Agent is detected automatically
2. View the full UA string at the top of the page
3. Click "Copy User Agent" to copy the string to your clipboard
4. Review the parsed details below for browser, OS, device, and engine information
5. Check the Browser Details and Display Information sections for additional navigator properties

## Understanding User Agent components

A typical User Agent string like `Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36` contains several parts:

- **Mozilla/5.0** — A historical compatibility token (nearly all browsers include this)
- **Platform token** — Your OS and hardware details in parentheses
- **Engine token** — The rendering engine (AppleWebKit, Gecko, etc.)
- **Browser token** — The actual browser name and version

Due to historical browser wars, UA strings often contain misleading tokens. For example, Chrome includes both "AppleWebKit" and "Safari" for compatibility reasons. This tool cuts through the noise to give you the accurate browser identity.

## Privacy considerations

Your User Agent string is one component of browser fingerprinting, a technique used to identify users without cookies. Combined with other signals like screen resolution, installed fonts, and hardware details, it can create a fairly unique profile. This tool runs entirely in your browser — no data leaves your device. If privacy is a concern, consider using browser extensions that randomize your UA string or using browsers with built-in fingerprinting protection.
