167 small apps, played together in Matrix rooms

webxdc apps are tiny web apps — games, polls, checklists, editors — that live inside a chat. The webxdc widget brings them to Matrix: add one to a room and everyone in it plays along, with the app's data travelling as end-to-end encrypted room messages. No app servers, no accounts. Below, 2 of them are shown by Ada, Ben, Cleo and Dev in real Element Web, 2 with more than one person.
