What is full-stack app?
A full-stack app includes both the front end (what users see) and the back end (database, authentication, business logic and APIs) — a complete, working product rather than just a screen.
Many AI tools generate only the front end, leaving you to wire up data and auth. A full-stack builder generates both and connects them.
BerryBell builds each app with an API and hosting, offers a Postgres database when the app needs one, and adds authentication and roles on paid plans — the full stack, from one prompt.
