X-Card (Discord Tool)
X-Card is a tool designed to anonymously implement John Stavropoulos' X-Card system into a Discord server. It was originally developed as a tool for myself to help me run Dungeons & Dragons' Curse of Strahd campaign module in a safe and fun way.
With this tool, a server owner is able to create a free page of buttons that their players can press to anonymously notify the Dungeon Master and/or their party that they feel uncomfortable with a given situation.
This tool simply sends well-formatted webhook requests to Discord via their webhook system, and is designed to be as simple-to-use as possible, as well as requiring no registration from dungeon masters or players.
It is used by over 250 active campaigns currently, and was released on January 20, 2021.
