Since a lot of people ask, the IRC frontend is built using PirxBotX.
For the osu! API, I rolled my own Java library. It's available in maven central. It also does some of the AR/OD calculations.
Since it came out, oppai (or rather a fork) is being used to make beatmap difficulty calculation more stable and to calculate difficulties for unranked beatmaps.
