The best AI app builders with a built-in backend
If you need a real backend generated for you — a database, authentication and hosting — rather than a front-end you have to wire up, BerryBell is the best pick: it provisions a Postgres database when your app needs to save data, adds end-user auth and roles on a paid plan, and deploys them. Base44, Replit, Lovable (via Lovable Cloud) and Bolt (via Bolt Cloud) also include backends; v0 connects databases through integrations such as Neon or Supabase.

How we ranked these
We compared each tool on what it builds, its backend (database and sign-in), code ownership, hosting and custom domains, and price, using each product's own pricing and documentation pages. Disclosure: BerryBell makes this roundup and ranks its own product first. Each entry says what that tool does best, so you can judge the fit for yourself.
BerryBell
Our pickProvisions Postgres on request, with end-user auth and roles on paid plans; deploys with the app.
Describe an app in plain English and a team of specialised agents (code, design, database, deploy, QA, debug) builds, tests and ships a full-stack app — with a Postgres database and hosting included, code you own, and end-user auth and custom domains on paid plans.
Built-in managed backend platform.
An all-in-one AI app builder with a built-in backend — database, auth and hosting on every plan. Strong for shipping internal-style apps quickly on a managed stack.
Built-in database, auth and hosting.
An AI app builder where you chat with Replit Agent to build and publish apps, with a database, auth and hosting built in — and a full cloud code editor alongside when you want it.
Built-in database, auth and storage via Lovable Cloud, or your own Supabase.
A popular, polished chat-to-app builder. Great for quickly turning prompts into working web apps; its built-in backend (Lovable Cloud) provides a database, auth and storage, or you can connect your own Supabase.
Built-in hosting, database and auth via Bolt Cloud.
An in-browser AI app builder by StackBlitz for JavaScript web apps (and Expo mobile apps); hosting, a Postgres database and auth are built in via Bolt Cloud, with Netlify or (on Pro and Teams) Supabase as alternatives.
Built-in database and auth (AI + visual editor).
A mature no-code platform for full web and native mobile apps. It now pairs AI app generation and an in-editor AI Agent with its visual editor — powerful and flexible, though the editor takes time to learn.
Connects to your data, plus built-in Retool Database.
A leader for internal tools that connect to your existing databases and APIs, now with an AI-native builder that generates React apps. Best for back-office apps rather than public-facing products.
Frequently asked questions
01 Which AI app builder generates a database and auth for me? + –
BerryBell offers each project its own Postgres database as soon as the app needs to save data, and on a paid plan you can turn on end-user sign-up and roles, with accounts stored in that same database. Both deploy with the app. Base44, Replit, Lovable (via Lovable Cloud) and Bolt (via Bolt Cloud) also include a built-in database and user auth.
