About this tool

Parse User-Agent strings to identify browser, OS and device. User Agent Parser runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • User Agent Parser is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
