Feastly is resellable source code for an UberEats / Grab / Foodpanda-style delivery business. It ships four coordinated surfaces on one shared backend — a Customer app, a Rider app, a Restaurant app (all Flutter) and a Next.js Admin panel that is the shared API, AI and realtime backend. Monetize it through per-order commission, deploy it anywhere, and keep zero paid-service lock-in: the realtime layer is self-hosted, email is plain SMTP, and the AI is fully optional.
