opentracker is a free (licensed as beerware) peer tracker software (a special kind of HTTP or UDP server software) that is designed to be fast and to have a low consumption of system resources.
OpenTracker runs several times faster than older tracker implementations and requires less memory. (For example, it runs fine with the limited resources of many embedded systems.) Several instances of the software may be run in a cluster, with all of them synchronizing with each other. Besides the (HTTP) opentracker may also be connected to via (UDP), which creates less than half of the tracker traffic HTTP creates. It supports IPv6, gzip compression of full scrapes, and blacklists of torrents. Because there have already been cases of people being accused of copyright violation by the fact that their IP address was listed on a BitTorrent tracker, opentracker may mix in random IP address numbers for the purpose of plausible deniability.
It runs completely in RAM, accounting for much of its speed advantage over other tracker software. It is written in C and based on the library libowfat that manages network connections. For some new functionality like the UDP support with IPv6 or the syncing of several instances of BitTorrent tracker software, new extensions to the BitTorrent protocol were made.
The world's largest tracker at The Pirate Bay switched from their selfmade software Hypercube to opentracker in the end of 2007.
The Norwegian Broadcasting Corporation uses it to distribute their own TV shows.
