Werewolf Moderator

Werewolf Moderator does for the game Werewolf (also known as Ones Night Ultimate Werewolf-style variants and classic multi-round Mafia-adjacent formats) what True Mafia does for Mafia: it stands in as an impartial host inside a group chat. Players join with a command, the bot privately deals out roles like Werewolf, Seer, Doctor or Villager, and it walks the group through alternating night and day phases, tallying votes and announcing who was eliminated each round.

What sets it apart is that it is fully open source, with the code published on GitHub and a dedicated site (tgwerewolf.com) documenting the rules and role list in detail. That transparency is reassuring for a bot that needs message-management permissions in your group — anyone can audit exactly what it does rather than trusting a black box. With roughly 87,000 monthly users, it has a smaller but clearly established audience, likely people who specifically prefer the Werewolf rule set over Mafia's.

Like any host bot, it only works as well as the group using it: you need enough genuinely active players willing to discuss and vote, and larger groups generally produce a more interesting game than a handful of people.
