What does this tool do?
The User-Agent Parser decodes the User-Agent string a browser sends to detect the browser name and version, operating system, and device type. It's useful for web developers, support teams, and anyone analyzing log files.

What it decodes
The tool takes the long, hard-to-read User-Agent string and extracts the browser engine, the browser name and version, the operating system and version, and whether the device is desktop or mobile. You can auto-fill your own browser's User-Agent or paste any string copied from logs to inspect it. All parsing is done locally in your browser, so the data you analyze stays on your device.
What it's for
Developers want to understand a visitor's real environment to reproduce bugs that only appear in a specific browser or operating system. Support teams quickly read device and browser details to assess a reported issue in the right context. For analytics and log review, the tool turns raw User-Agent records into readable, comparable data, making it easier to spot patterns across many requests.
