The UA Tracker Project was developed to analyze unique user-agent strings from everyday web traffic. User-agent data is collected from any website displaying the UA Tracker icon. User-agents are logged in a database, counted, and displayed in a table. Unique strings are saved to a simple plain-text file, with the most common strings located at the top. Since the data is updated in real-time, the file is always up-to-date with the most common user-agents. The text file is available for download, and the database can be searched and viewed by the public.
