Fractal is a development platform purpose-built for shipping ChatGPT and MCP apps rapidly, handling architecture planning, AI-assisted coding, and one-click deployment. Built by MIT alumni who participated in the MCP-UI working group, Fractal distills months of platform expertise into a streamlined workflow that reduces prototype cycles from weeks to hours. It targets indie builders, non-technical founders, and enterprise product teams who want to move fast in the ChatGPT app ecosystem without deep infrastructure knowledge.
