Dyno is still one of the most comprehensively complex and feature-rich free Discord bot out there. While the free tier of Mee6 only offers 3 custom commands, Dyno custom commands are as far as we can tell, limitless! You can change how the command will react to the user, change who can execute the command and where, add cooldowns and arguments, and add a whole bunch of variables and advanced variables that can make your custom command positively sophisticated!
