User agent string detection system was developed for ASAP Consulting, s.r.o. where I previously worked. Tool from ASAP Consulting s.r.o. for detailed user agent string analysis using an online form. Includes databases of browsers and robots. Was primarily designed for web statistics system Cluso. Due to the possibility of further use has been made available on this site. System API is free. In case of high number analyzed request free API can be restricted by number of requsets per hour.
