Free AI App Builder: The Real Limits Behind Every Free Tier
Free is a marketing word until you see the metering behind it. Every AI app builder free plan on this page is capped by a specific, published unit, credits, tokens, messages or projects, and none of them is built for running sustained production traffic. This page lists what each vendor actually publishes, ordered from the most generous published allowance to the least.
For the full scored ranking across every criterion, see the AI app builder rankings. If you already know what you are building and want the right category of tool rather than the cheapest one, start at AI app maker.
Read this before comparing numbers
A free tier is built for evaluation, not for sustained production traffic. Every allowance below resets, expires, or runs out, so treat the free plan as a way to confirm a tool fits your project before you spend anything, not as a place to run a live product indefinitely.

The one builder with no published free plan
Softr publishes no free plan: not published in the documentation we checked. It still made this comparison because it is a serious builder, best known for client portals and internal tools, but you should expect to pay from the start rather than trial it for free.
This is exactly the kind of gap we score as not published rather than guess at. If Softr publishes a free plan later, this page will move it into the ranked list above.
Free plan does not always mean the same feature set
A metered allowance is only half the picture. Some capabilities are published as arriving on a paid tier rather than the free one, for example FlutterFlow's code download, APK download and one-click App Store deployment, which sit on its paid Basic plan above the free tier listed here. Before you build past a prototype on a free plan, check whether the specific capability you need, such as code export or a custom domain, is confirmed on the free tier itself or only on a paid one, using the full per-builder verdicts.
If your priority is a category of tool rather than a price, start at AI app maker instead, which routes by what you are building. For a plain definition of what these tools produce and how a generator differs from an ongoing builder relationship, see AI app generator.
Free AI app builder FAQ
01What does free actually mean on an AI app builder?
It means a metered allowance, not an unlimited plan. Every free tier on this page is capped by a specific unit: credits per month, tokens per day, messages per day, or a project count. None of the sixteen builders compared here offer unlimited free use at production scale.
02Which AI app builder has the most generous free plan?
Bolt.new publishes the largest concrete numeric allowance, 300K tokens daily and 1M tokens per month. Rocket.new's 20 free credits are smaller in number but do not expire, which suits infrequent building better than a daily reset does.
03Is any AI app builder completely free forever?
No. Every free plan in this comparison is designed to let you evaluate the tool, not to run a live product indefinitely. Fifteen of the sixteen builders publish a free tier, and Softr is the one exception, since its documentation does not publish a free plan at all.
04Which AI app builder has no free plan?
Softr. The dataset behind this page found no published free plan in Softr's documentation, so it is listed separately rather than guessed at.
05Do free plans include the same capabilities as paid plans?
Not always. A free plan is usually the same underlying product with a smaller allowance, but some capabilities, like FlutterFlow's code download, APK download and one-click App Store deployment, are published as arriving on a paid tier rather than the free one.
06Can I build a real product on a free plan and upgrade later?
Yes, for the builders that publish code export, since your work is portable if you outgrow the free allowance. Totalum, Lovable, Bolt.new, Anything, Rocket.new, Emergent and FlutterFlow all publish code export. Builders without it, such as Bubble, Glide, Adalo and Softr, keep the project inside their own runtime, which is worth knowing before you invest heavily on the free tier.
