Analyze UA

This tool was developed for user agent string analysis. Our analysis gives you information on client SW type (browser, webcrawler, anonymizer etc.), which OS is used by the client and moreover we display detailed analysis of UA fragments together with the URL of client's SW producer and our commentary.

Insert any user agent string in this field and choose "Analyze". If you want to analyze your browser user agent string choose "Analyze my UA".
