Paste any User-Agent string, or load your own browser's, to see it parsed into browser name and version, rendering engine, operating system, and device type using pattern matching.
Frequently Asked Questions
- Can I check my own browser's User-Agent?
- Yes, there's a button to load your current browser's User-Agent string automatically, so you don't have to find and copy it yourself.
- How does it detect bots?
- It looks for keywords like 'bot', 'crawl', or 'spider' in the User-Agent string and flags the device type as Bot when found.
- Will it parse every User-Agent perfectly?
- Not always. Detection is pattern-matching based rather than a database lookup, so unusual, custom, or spoofed User-Agent strings may not be identified accurately.
