A year ago, AI app builders produced demos. Today they produce products. This guide compares the leading platforms on the questions that actually decide the choice: what you get from a prompt, what you own afterwards, and what it costs once you use it seriously.
How we evaluate
Same lens for every platform: how far a plain-language spec gets you, and how much human work remains.
Ownership and exit: what happens when you outgrow the platform or want the code.
Cost structure at real usage, not the teaser price.
Lovable: the default pick for most founders
Lovable writes real React code with a built-in backend for data, sign-in, and hosting, and syncs it to GitHub on every plan, including Free. Architecture decisions are ones a senior engineer would defend. Costs scale with how much you iterate, so the free plan is the right place to judge it on your own idea.
Base44: the most ready-made
Base44's pitch is completeness: backend, sign-in, payments, and hosting are built in, plus one-click integrations with tools like Gmail, Slack, and HubSpot, so a prompt becomes a usable, hosted app with zero wiring. Two-way GitHub sync starts on its Builder plan, which is the trade that keeps everything this managed. Our full review covers where that trade bites.
The rest of the field
Bubble remains the deepest visual builder with a decade-old ecosystem — slower to a first version, far more precise on complex logic. Framer wins for marketing sites where design fidelity is everything. Neither generates full applications from a prompt the way the top two do.
Buy the tool that matches your exit plan: if you will eventually hire engineers, choose a builder that exports code.
Verdict
Choose Lovable if you want a working app now and your code in GitHub from day one — the right default for most founders. Choose Base44 for internal tools and apps built around payments and business-tool integrations. Both have free plans, so judge them on your own use case before paying.
