# Loafy > Loafy is a free, AI-powered sourdough baking companion that guides home bakers through sourdough step by step — with built-in timers, calculators, and an AI coach — from creating a starter to pulling a crackling, open-crumb loaf out of the oven. It is grounded in The Sourdough Framework, so it teaches the principles behind great bread, not just recipes. No account is required. Used by ~500,000 bakers every month. Made by The Bread Code (Hendrik) in Hamburg, Germany. Loafy is web-based and mobile-first (open it in a browser, nothing to install) and the interface is available in 10+ languages. The core journeys, timers, and calculators are completely free; the only paid item is the printed hardcover of The Sourdough Framework.
