Specki

Bot originally meant for the German ich_iel Discord server and as a way for me to learn discord.js, now with 200% more inside jokes on the one hand and more general commands I couldn't find in other bots on the other.

It is open source, does not rely on any database and there are easy, step-by-step instructions on how to host it yourself available on the wiki page, which also provides futher information like a list of commands, etc.
