Free online parser tools: User Agent parser to identify browser, OS, and device from any UA string, and URL parser to break down any URL into its components.
Every request your browser makes includes a User-Agent string and a URL. They look simple on the surface, but there's a lot of information packed into them. Here's how to extract it.
User Agent Parser
The User Agent Parser takes any User-Agent string and tells you exactly what it represents:
- Browser — Chrome, Firefox, Safari, Edge, or something else
- Browser version — Exactly which version
- Operating system — Windows, macOS, Linux, iOS, Android
- Device type — Desktop, mobile, tablet, bot/crawler
- Engine — Blink, WebKit, Gecko, etc.
Perfect for checking what your own User-Agent looks like, analysing server logs, or debugging browser-specific behaviour.
URL Parser
The URL Parser breaks down any URL into its components:
- Protocol (http, https, ftp)
- Hostname and port
- Path
- Query parameters (as key-value pairs)
- Fragment/hash
- Username/password (if present)
Invaluable for debugging redirects, constructing API requests, or understanding complex URL structures.
