About the User Agent Parser

The User Agent Parser breaks a user agent string into browser, engine, operating system and device, and shows your own. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Reading a user agent from a server log.
  • Checking what your own browser reports.
  • Debugging a device-specific bug report.

Frequently asked questions

Does the User Agent Parser cost anything?
There is no cost and no cap. The User Agent Parser is not a demo of a paid product, so nothing is held back or watermarked.
Is my data uploaded anywhere?
No. The User Agent Parser runs entirely in your browser using JavaScript. Because the work happens locally, the utility also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What is the User Agent Parser used for?
Typical uses: reading a user agent from a server log. Checking what your own browser reports. Debugging a device-specific bug report. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will this work on a tablet?
Yes. The page is responsive and the utility works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
