Dungeon Mastron
Dungeon Mastron is an open-source storytelling platform that empowers anyone to design, build, and play branching narrative games without writing code. Its visual node editor lets creators wire together pages, choices, dice rolls, inventory, and media into complete interactive experiences, outputting a single game file. The web-based player runs these games instantly in the browser with no installation or account required, making sharing as simple as sending a link. Additionally, an AI Companion provides a prompt template for large language models to co-author validated game files, ensuring structural integrity and zero dead ends. The project is MIT-licensed, free forever, and community-driven.
