User-Agent Parser

Identify broad browser, engine, platform, and mobile tokens from a User-Agent string.

This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.

Interpretation notes

How it works

User-Agent strings are compatibility hints, not trustworthy device identity. This parser reports only broad tokens it can support from the text and labels every result as a heuristic. A missing mobile token is treated as unknown unless desktop-like platform evidence is present; no endpoint is contacted.
