What is User-Agent Parser?
User-Agent parser powered by ua-parser-js. Detects browser, engine, OS, device type, and flags bots.

- Bot/crawler detection
- Bulk CSV export
- Pre-filled with your UA

Frequently Asked Questions
- How does bot detection work?
- The tool looks for common patterns (bot, crawler, spider, slurp, bingbot…) in the UA and shows a flag badge.
- Can I parse multiple UAs at once?
- Yes, bulk mode accepts a list (one UA per line) and exports a CSV with browser, OS, device and bot status.
- Are UAs sent to a server?
- No, parsing uses the ua-parser-js library running entirely in your browser.
