- Main article: HostServ

- Main article: BotServ
BotServ is the service that maintains custom services' bots for channels. It provides a basic framework for setting up a custom basic bot for users who can't make their own, can't host their own, or just simply prefer the convenience of having a services-controlled bot. BotServ bots will sit indefinitely in their assigned channels even if they are otherwise empty, so they can be used to keep channels open.
