# Molecule.dev > An AI-first, composable package ecosystem for building full-stack apps that scale. Molecule.dev generates real, production-grade full-stack code from hundreds of composable, swappable `@molecule/*` packages — not throwaway prototypes. Its bond system keeps generated code decoupled: swap a provider (Stripe → Apple Pay, PostgreSQL → MySQL, one OAuth provider for another) by changing one line, not rewriting the app. ## Core ideas - [How it works](https://www.molecule.dev/): describe an app in plain language; an AI harness composes the right packages and wires them via the bond system. - [Templates](https://www.molecule.dev/templates): start from a real full-stack app and shape it with AI — no blank-page setup. - [Pricing](https://www.molecule.dev/pricing): start free and scale as your app grows. ## Resources - [GitHub (molecule)](https://github.com/molecule-dev/molecule): the open-source package ecosystem. - [Blog](https://blog.molecule.dev): updates and deep dives. ## Legal - [Terms](https://www.molecule.dev/terms) - [Privacy](https://www.molecule.dev/privacy) - [DPA](https://www.molecule.dev/dpa)
