By a decent margin the most popularStats parser. It's actually big enough it's in the Google spellcheck. Running only on windows, it's closed source, and sharewhere, and not exactly the speedeamon of other engines, but if you want to go with the flow, or go with the classic, then this is your ticket.

PISG (or Perl Irc Statistics Generator) is open source and relativley popular in both the linux and windows community, it also has the unique atribute of being the only engine to work under MacOS too. It actually should work anywhere there's perl available. Not the fastest around, but it's opensource, and it's popular.

Open source, and POSIX based, it looks likes it's dead, although from the sourceforge stats it still pulls about 2 downloads a day!

A continuation on the now dead ISG project it's open source and seems to be updated frequently, it's a rather mature stats engine for Linux/BSD.

Built in python it's POSIX based, shows a pretty good caching system and a unique stats page, but under spuratic development.

stats.mod is (i beleive) a plug-in for eggdrop that generates realtime stats. A very different style of program/mod from anyother listed on this page.

Despite the name it SHOULD work with SpiffyStats, basicly it causes eggdropp to create mIRC compliant logs.

Working with both Eggdrop and Irssi it simply creates mIRC compliant logs.

Fairly straight-forward, converts dancerbot/dancer logs to mIRC.

IRCLC converts PIRCH and dIRC log files into mIRC style log files.
