What are some nice sources for User-Agent strings?

  • I'm testing a library that processes queries based on User-Agent. In my tests, I'd like to feed it as much strings as possible.

    Where can I find a public collection of User-Agent strings?

    I'm mainly interested in "real" strings, but a collection of specifically interesting strings could be of use (like examples that are likely to put stress on parsers). Plain newline-delimited list is OK.

  • I searched Google for "User-Agent strings" and found this and this and this. If you work for a company with a website, you might try asking them for a list.
