Giovanni

Giovanni is a feature-complete general purpose Discord bot built to rival Gaius and Dyno, with a few fun games thrown in. It's built to be as blazing fast as the Discord API will allow. Also, as a fairly unique feature, it supports Lua scripts to provide custom commands.

Fairly typical features include ranking, custom commands, moderation and auto-moderation support, casino games, economy system, and voice moderation. Somewhat unique features include a captcha and bouncer system (where new users have to be approved by a moderator before joining the main server), moderator presence system, a unique game called Fate of the Cards, disciplinary discussion channels, and the previously mentioned Lua support.

Giovanni is closed source and currently pre-alpha. Once it's released, most features will be free, with a few premium features available for $5 USD per month per server.
