The Best Base44 Alternative

One allowance, no two kinds of credits.

Base44 is a fair comparison because, like JustCopy, it ships a backend. The differences are in what it costs to keep building, when you get your own domain, and whether anyone checks the app works.

Base44 is a no-code AI app builder, owned by Wix since 2025, with a built-in backend and a credit system: message credits for building and integration credits for running the app.

Why people look for a Base44 alternative

Two credit meters

Building spends message credits; a running app spends integration credits. Both refresh monthly and do not roll over, so a busy month can stall on either.

A small free plan

25 message credits a month, plus 100 integration credits a month for the running app. Enough to try it, not enough to finish an app that needs a few rounds of changes.

Own domain at $40

A custom domain, backend functions and GitHub arrive on the Builder plan, about $40 a month billed yearly. Starter at about $16 to $20 does not include them.

Nobody tests the app

Base44 generates and previews. Whether the sign-up, the form and the upload actually work is for you to find out.

Base44 alternative: questions people ask

What is the best Base44 alternative?

JustCopy.ai, if what stopped you was credits or the price of your own domain. It has one allowance that resets daily, puts an app on your own domain from $9.99 a month, ships the same kind of built-in backend, and tests every build on screen before calling it done.

How does Base44 pricing work?

As of September 2026 Base44 has a free plan with 25 message credits a month and 100 integration credits a month, and paid plans at about $16, $40, $80 and $160 a month billed yearly (monthly billing is about 20 percent more). Building spends message credits and a running app spends integration credits.

Does Base44 include a custom domain?

From the Builder plan, about $40 a month billed yearly. JustCopy includes one custom domain on Hobby at $9.99 a month, two on Starter and five on Professional.

Is Base44 owned by Wix?

Yes. Wix acquired Base44 in 2025. The product still runs as its own builder, and its pricing and credit system are separate from Wix plans.

Which has the better free plan?

JustCopy gives three AI builds a day with no monthly cap, five projects with live links, and unlimited text, colour and section changes. Base44 gives 25 message credits a month. A few rounds of changes use up a Base44 free month; on JustCopy they are free.

Do both have a backend built in?

Yes. Both ship a database and user accounts without a separate service. JustCopy also ships file storage with lasting links, Stripe payments, email, visitor analytics and the option to charge your own users at your prices.

Does either tool test the app it builds?

JustCopy does. After every build it uses the app on screen (sign up, add an item, upload a photo, delete, reload) and shows a tick or a cross for each step; a cross is fixed at no charge. Base44 previews the app; checking it is up to you.

Can I move from Base44 to JustCopy?

There is no importer. The practical route is to describe the app again, or name the published Base44 app so the AI can read its structure and build a new one in that spirit, then paste in your data through the Data tab.

Build the app, and let it test itself

Describe it in a sentence. The backend is built in, the build is checked on screen, and the allowance resets every day.
