About this tool
The User Agent Parser takes a raw user agent string and breaks it down into readable information about the browser, operating system, device type, and rendering engine behind a web request. It is useful for developers, QA testers, and anyone who works with web server logs or needs to understand what environment a visitor was using when they hit a page.
Reach for this tool when you are debugging compatibility issues, analysing server access logs, or verifying how your application identifies different clients. It saves you from manually decoding long, cryptic UA strings that are otherwise difficult to read at a glance.
How to use it
- Copy the full user agent string you want to analyse from your logs or browser settings.
- Paste the string into the input field on the tool page.
- Click the Parse button to submit the string for processing.
- Review the breakdown showing browser name, version, OS, and device type.
- Copy or note any specific fields you need for your debugging or reporting work.
Pro tips
- Test edge cases by pasting UA strings from older browsers or bots to see how they are categorised versus modern clients.
- Your own browser’s UA string is usually available at about:blank via the console command navigator.userAgent, no copy-paste hunting needed.
