About User-Agent Parser
The User-Agent Parser decodes any User-Agent string into clean, labeled cards: browser name and version, rendering engine, operating system and version, device type, vendor and model, plus CPU architecture where the string reveals it. One click loads your own browser's User-Agent for an instant self-check.
It also flags bots and crawlers, which makes it handy for log analysis — paste a suspicious UA from your access logs and see immediately whether it claims to be a search engine spider or a real browser. The raw string stays visible alongside the parsed breakdown for reference.
Parsing happens entirely in your browser; nothing you paste is uploaded. It is a free, quick alternative to eyeballing the notoriously misleading UA syntax, where almost every modern browser claims to be Mozilla.
