LisaBotCat
LisaBotCat (aka Botcat) is my bot. The simple explanation is that it uses a RabbitMQ cluster running on a bunch of Raspberry Pis. Both chat (IRC) and Twitch PubSub messages are processed and pushed into the message queue. Those messages are picked up and acted upon by various worker scripts.
Botcat has parts that are written in Java, Javascript, C++, Node, PHP, and bash scripts. I am always adding features as the need arises. As of the writing of this panel, the most recent feature is automatic channel point reward redemption.
I've configured Botcat to run in a few of my friends' channels. I may open it up to the public one day, but I have no plans for that right now. There's really not much that Botcat can do that other bots are already doing.
