The best AI app builders that let you export your code
If avoiding lock-in matters, choose a builder that gives you real code. BerryBell provides the full source, editable in-browser on every plan and exportable to GitHub or as a zip on a paid plan; Lovable (two-way GitHub sync on every plan), Bolt, Replit and v0 also produce genuine code, and Base44 syncs to GitHub on its Builder plan and up. Managed platforms keep more of the stack on their side, so check export terms before committing.

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 pickFull-stack source you own — edit in-browser on any plan, sync to GitHub on a paid plan.
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.
Real code; download as a zip or sync to GitHub.
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.
Full project code in a cloud IDE.
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.
Exportable Next.js/React code.
Vercel's AI agent for building Next.js apps — outstanding for React/Next.js interfaces and design-to-code, with one-click Vercel deploys and databases added through integrations like Neon or Supabase.
Real code with two-way GitHub sync on every plan.
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.
