How to Rebuild a Base44 Website With AI

Introduction

Base44 is one of the friendlier AI app builders. It can turn a plain-English prompt into a working site or app quickly, and it does a good job hiding the technical pieces that make other app builders feel intimidating. If you ask it for a lot at once, it can also feel surprisingly generous.

The problem usually shows up later. Websites are not finished in one prompt. After the first version, you still have to rewrite sections, swap images, fix spacing, add pages, adjust mobile layouts, clean up navigation, and make dozens of small judgment calls. Base44 charges by message credits, so every little "make this headline shorter" or "change that image to black and white" can eat into the same limit.

Instead of using a strict message limit to polish your website, you can move the site into a tool built specifically for website editing. In this guide, I'll show you how to rebuild your Base44 website in Repaint.

Why Repaint

Repaint is an AI platform optimized for building and editing websites. The core idea is similar to Base44: you describe what you want and the AI builds it. But Repaint is designed around the work that happens after the first draft:

• It's better for lots of small edits. Most website work is not one giant prompt. It's a long sequence of copy, image, layout, and mobile adjustments. Repaint's usage is designed around that kind of ongoing website refinement, so a small tweak costs a small amount.
• Its allowance resets weekly, not monthly. Base44's message credits reset monthly, so one heavy editing session can affect the rest of your month. Repaint gives you a weekly allowance, which makes it easier to keep polishing without waiting for a monthly reset.
• It's better at importing content. Repaint has dedicated tools for pulling text, images, pages, and styles out of existing websites, so you can bring over a Base44 site without manually copying everything.

How Migrating Off Base44 Works

The simplest way to move off Base44 is to give Repaint your live website URL. Repaint visits your site the way a visitor would, reads your content, pulls in your images, and uses them to rebuild the website. This works on Base44's free plan, since all it needs is a live website.

The other option is to export your code from Base44 and upload it into Repaint. This lets Repaint use the original more exactly, because it doesn't have to guess when it recreates the design. But code export requires a paid Base44 plan.

Either way, you'll end up with a full website that you can edit by chatting with AI. Once you're happy with it, you can publish directly from Repaint and connect a custom domain.

Step 1: Import your content

There are two ways you can import your content into Repaint:

1. Share the live website URL
2. Export your code from Base44, and import it into Repaint

We recommend the second option if you have a paid Base44 plan and you want the new site to look exactly like the original. If you're planning to redesign the website anyway, exporting the code is overkill, and it's simpler to just share the live URL with Repaint.

Importing from a URL

Repaint can redesign any publicly accessible website on the internet. For this to work, your Base44 site has to be published. Base44 has a one-click Publish button that puts your site live at a URL like https://coastal-design-studio.base44.app.

First, open your site in Base44. Then:

1. Click Publish and copy the URL
2. Go to Repaint, paste the URL, and submit
3. Create your Repaint account

Importing as code

If you have a paid Base44 plan, you can export your code directly from the editor. Rather than copying files one at a time, you can download the whole project as a .zip and hand that to Repaint:

1. Open your app in Base44
2. Open the ellipsis (…) menu in the top right
3. Click Export project as ZIP
4. Go to Repaint and create your account
5. Upload the .zip and submit

Either path starts the website building process. Repaint will scan your site, copy text and images, and take screenshots of each page to understand the design. From there, you just have to talk to Repaint to finish the process.

Step 2: Plan your new website

Repaint is capable of copying the original, completely redesigning it, or anything in between. Before it starts building your website, it'll ask you a few questions to understand what you're looking for.

Since you're already rebuilding, it's a good time to experiment with the style to see if there's anything else you want to try. You can have Repaint generate style samples for you to choose from, so you're not locked into the first look you land on.

Import content

If you have more information to include, share it now. Repaint can use information from other websites, Google businesses, PDFs or other files, and images. The more it learns before building the site, the less you'll have to polish later.

If you have multiple source sites, like an older website in addition to the Base44 one, you should give Repaint both. It can use the old website for information to transfer, and the new one as a style guide. When in doubt, share lots of information and let Repaint figure out how to use it.

Once you and Repaint agree on the plan, it'll build your new website!

Step 3: Generate your website

Repaint typically spends a few minutes building the first version of your website. The exact duration varies, depending on how much content it has to migrate and how large the new website is. A large site with dozens of pages might take over ten minutes.

When it's done, Repaint will automatically open a preview of your new website. The first version usually has some rough spots: text that got cut off, images in the wrong place, or spacing that's a bit off. That's expected. You can fix anything that's out of place by chatting with the AI.

If your Base44 project uses backend features, those won't come over. Repaint builds the visual website that people see, so anything behind Base44's Users, Data, or Integrations tabs, like logins, a database, or connected services, won't transfer. Most marketing websites don't use any of that, so it's not an issue. But if you've built a real app on Base44, migrating would mean leaving that functionality behind.

Step 4: Make adjustments

After generating your site, there might be a few quirks to work out. Repaint translates your website into its own format, so it's possible some details will be lost in translation. Or if Repaint redesigned your Base44 site, there will be a lot of new content to review.

The editing workflow is the same as Base44. You change anything on your website by chatting with AI. "Add an FAQ section." "Swap the hero image for a photo of our team." "Tighten up the spacing in the footer." If you need new images, Repaint can generate them for you on the spot. And because a small edit only costs a small amount of usage, you don't have to ration these little adjustments the way you would against Base44's message credits.

You should start by evaluating the visual style. Make sure the colors, fonts, and layouts all look good. Your visual style establishes patterns that the AI will naturally use for any new content it creates, so getting it polished early is faster than polishing it after you build out dozens of pages.

Once you like the style, you can work through the content and make sure the text is accurate, images are in the right places, links work, and everything looks good on mobile.

Review SEO content

If your Base44 site was getting search traffic, it's worth paying attention to SEO during your migration. We have an entire website redesign SEO guide if you want to learn more. At a high level, you just want to make sure the new website has the same page URLs, and the same content on them.

Google builds rankings for individual pages on your website, tied to their URLs. If you move to a new platform and those URLs change or disappear, Google treats them as new pages with no history, and you lose the traffic they were earning. And if you change the content, Google might decide the new versions are no longer relevant to search queries and stop ranking them.

You can ask Repaint to compare the URLs on your new site to the Base44 one to see if there are any differences. If you imported the code directly, it's likely nothing changed. But if there's anything changed or missing, Repaint can help fix it as long as you ask.

When your site looks good and the content is correct, you're ready to publish.

Step 5: Publish your website

When you're ready to publish your new website, open your Repaint project and click Publish in the top right corner. Your site goes live on a Repaint URL that you can share with anyone. It will look similar to your Base44 URL, like this: https://careful-tiger-5jd92kjd.sites.repaint.com

At this point, you have two websites live: one on Repaint, and one on Base44. If you have a custom domain, it still points to your Base44 site, so nothing has changed for your visitors yet. When you're ready to make the switch, you can transfer your domain.

Step 6: Transfer your domain

When you're ready to officially swap, you just need to point your domain to the new Repaint website. To do this in Repaint, you simply tell the AI to connect your domain. It will give you DNS records to add. This requires a paid plan; you can see pricing details here.

Your domain is separate from your Base44 site. It's likely registered with a separate domain provider like GoDaddy, Namecheap, or Cloudflare. Either way, your domain should stay on that platform. You don't need to move it. You just need to update the settings so your domain points to your new Repaint site instead of the Base44 one.

Don't worry if you've never handled DNS settings before. Repaint can walk you through it. It can give you custom instructions based on your provider. DNS changes can take 20 minutes or more to take effect. Once you set the DNS records, you can have Repaint check your live records to see if it successfully propagated. Once it verifies everything is set up correctly, you're done.

After you transfer your domain, you don't need a paid Base44 plan for hosting anymore. You can cancel your Base44 subscription anytime.

Conclusion

Base44 is a friendly way to turn a prompt into a working site, but its message credits make the finishing work, the dozens of small edits every website needs, feel expensive. Repaint gives you a more website-friendly place to bring it over, polish the pages, improve the copy and visuals, and publish when you're ready. You can migrate by sharing your live URL or exporting your Base44 code, then keep editing by chatting with AI, where a small change costs a small amount. And since your Base44 site stays live the whole time, there's little risk in trying Repaint before you switch.

FAQ

Why switch from Base44 if Repaint is also an AI builder?

They're similar tools, and both let you describe what you want and build it. The difference is focus. Base44 is a general app builder that meters work by message credits, so a small edit and a big build can cost the same. Repaint is built specifically for marketing websites: its usage is sized for the long tail of small edits a website needs, and it runs on a weekly allowance instead of monthly credits.

Why do small edits feel so expensive in Base44?

Because Base44 charges per message, not per amount of work. Asking for twenty-five pages at once and asking to shorten one headline both spend a message credit. That's fine for big one-shot builds, but websites are mostly small refinements, and those add up fast against a fixed credit count. Repaint meters by the work the AI actually does, so little changes stay cheap.

Won't I hit the same usage limits in Repaint that I hit in Base44?

You'll generally get further. Base44's free plan gives you 5 message credits per day, capped at 25 per month, and paid plans add a monthly credit pool. Repaint runs on a weekly allowance and prices work by how much the AI actually does, so routine website edits go further. For the steady stream of small changes a website needs, that stretches a lot longer.

Will migrating use up my Base44 credits?

No. If you import by sharing your live URL, Repaint just visits your published site the way any visitor would, so it never touches your Base44 account. Exporting your code is free of credits too, since you're only downloading files you already have. The migration runs on Repaint's usage, not Base44's.

Do I need a paid Base44 plan to migrate?

For the simplest path, no. Importing from your live URL only needs your site to be published, which works on Base44's free plan. You'd only need a paid Base44 plan if you want to export your full code for a more exact rebuild. If you're redesigning anyway, you can skip the export and just share your URL.

What happens to my Base44 site during the migration? Can I keep both?

Nothing happens to your Base44 site. The two are completely separate, so your Base44 project stays live and untouched while you build the new one. Once you're happy with the Repaint version, you can point your domain at it. If you'd rather stick with Base44, you don't have to do anything.

What if my Base44 project is a full app with logins and a database?

Then Repaint probably isn't the right fit. It rebuilds the visual site people see, not the infrastructure behind it, like the users, data, and integrations Base44 manages for you. If your project is a real app with that functionality, migrating would mean leaving those pieces behind.

Can Repaint match my Base44 design exactly?

It depends on how you import. If you export your code, Repaint works from the original and can get very close. If you import from your live URL, it recreates the design from what it can see, so it'll clearly look like your site but it's more likely to drift in a few places. Either way, you can fine-tune anything by chatting with the AI.

How long does the migration take?

The first build usually takes a few minutes, though larger sites with many pages can take ten minutes or more. After that, time-to-publish comes down to how many adjustments you want to make. Most sites can be migrated and polished within a few hours.

How much does it cost to migrate from Base44 to Repaint?

It's free to import your site, edit it, and publish to a sites.repaint.com address. The free plan covers building and launching a simple site, with a weekly editing allowance and a Repaint badge. Paid plans start at $20/month billed annually, or $25/month monthly, which adds a larger allowance, removes the badge, and lets you connect a custom domain. You can see the full breakdown on the pricing page.

Can I migrate just one page to try it first?

Yes. You can import a single page to see how it comes out before committing to the whole site. Once you like what you see, you can ask Repaint to build out the rest.

Will I lose my search rankings when I migrate?

Not if you keep your URLs and content consistent. Google ties rankings to individual page URLs, so you want your new site to reuse the same URLs and largely the same content. You can ask Repaint to compare your new URLs against the original and fix any gaps. There's more in our guide to preserving SEO when you import a site.

What happens when the AI makes a mistake? Can I undo changes?

Yes. Repaint saves a version of your site every time you make a change. If something comes out wrong, you can ask it to go back, or restore an earlier version from the version history yourself. Nothing is permanent, so it's safe to experiment.
