System: Searchable Directory of User Agents: Unclassified

The following is a directory of user agents, including their source and general purpose as far as we can determine. Most entries link to an "official" site containing more detailed information. You can also paste a UA from your logs into the form below, hit [Go!] and see a list the relevant agents.

We currently have 946 distinct user agents in our database representing everything from search engines to software components and spambots. These have been collected from our log files over a number of years and researched manually.

Search for User Agent

To use this form just copy and paste an entire User-Agent string from your server log file into the input box and then submit the form. The search is case-sensitive so "nokia" will not match "Nokia".

Most user agent strings now contain a number of separate components so the search will return a list of everything that has a match in the database.
