About User Agent Parser

Analyze HTTP User-Agent strings. Automatically detect your current browser signature, or paste any User-Agent string to inspect browser name, version, operating system, and rendering engine.

Unlike traditional web tools that send your personal data, uploaded photos, or sensitive text to remote cloud servers, our User Agent Parser operates strictly inside your client browser sandbox. This guarantees high processing speeds without network throttling, and ensures your data privacy is completely preserved.
