Monster Browser is a server browser for Quake 3 mods, and standalone games using the Quake 3 engine. It's well suited for mods with few servers, since that's what I mostly play myself. The filter capabilities are limited to 'Not empty' and 'Has humans', but that's enough most of the time.
Downloads and additional information.
Project page with source code, etc.
Please post any feedback you might have. If anyone's interested in helping out with the coding, let me know. I might not be able to do much more work on this myself, but I'll consider handing over the source code to someone else. It's coded in D, with DWT for the gui. Both very pleasant technologies to work with.
