User Agent Parser

Parse any User-Agent string into browser, OS, engine, and device information.

Frequently Asked Questions

Is User-Agent detection reliable?

UA strings can be spoofed and browsers are phasing out detailed UAs via User-Agent Client Hints. Use UA parsing for telemetry and analytics, not security or feature gating.

Where does the UA string come from?

You can paste any UA string. We also provide a button to load your current browser's User-Agent from navigator.userAgent.
