The AI builders that hand you a complete, buildable codebase today are FNJ, Lovable, Bolt.new and v0, with Relume (React export) and Hostinger's AI Builder (in agentic mode) close behind. Webflow exports static HTML, CSS and JavaScript on paid Workspace plans, but its CMS, ecommerce and forms stay behind. Framer, Wix, Squarespace and Durable keep your site on their own hosting and don't offer a full code export.
FNJ publishes this blog and makes one of the builders compared below, so weigh our view with that in mind. Every competitor fact here comes from the vendor's own website or docs. Checked October 2026; plans and features change, so confirm on each vendor's site.
What "exports code" should mean
Plenty of builders say you can take your content with you. That isn't the same as owning the site. For this comparison, a builder exports code only if you can download (or push to Git) a project that a developer can open, build and deploy on a host of their choosing, with no account at the builder still running behind it.
Three levels are worth separating:
- Full source export. A project folder or repository with pages, styles, scripts and assets. You can host it anywhere.
- Partial export. Static pages come out, but features that depend on the vendor's servers (CMS, store, log-ins, forms) stop working.
- Content export. Text and images in a format such as WordPress XML. The design stays behind.
Our guide to testing whether an AI builder's export is real turns this into a checklist you can run on any tool. FNJ's own approach is on the AI website builder with code export page.
The comparison at a glance
| Builder | What it builds | Code export | Must you host with them? |
|---|---|---|---|
| FNJ | Marketing websites | Next.js project, static HTML, or push to your GitHub branch | No, FNJ doesn't host sites |
| Lovable | Web apps and websites | ZIP download (paid plans), two-way Git sync | No |
| Bolt.new | Apps and websites | ZIP download, GitHub sync | No |
| v0 by Vercel | Full-stack web apps, landing pages | Export code, two-way GitHub sync | No, though publishing goes to Vercel |
| Relume | Marketing sites from a sitemap and wireframes | Export to React, Webflow or Figma | No, hosting is optional |
| Hostinger AI Builder | Websites, stores and apps | Agentic mode: React and Vite project ZIP. Manual mode: content only | Hosting is bundled; exported agentic code can move |
| Webflow | Websites with CMS and ecommerce | HTML, CSS, JS and images on paid Workspace plans | Only for CMS, ecommerce, user accounts, forms and search |
| Framer | Marketing websites with CMS | No HTML export for self-hosting | Yes |
| Wix | Business websites with built-in tools | No | Yes |
| Squarespace | Business websites | Some content as WordPress XML, no styles | Yes |
| Durable | Small-business site plus CRM and bookings | Not offered | Yes |
Builders that hand you a full codebase
FNJ
FNJ's AI builder designs a complete, responsive marketing website from your description plus at least one reference: a screenshot, the link of a site you like, or your project's ZIP or folder. It plans a design system first, then builds each page on a live canvas at three widths (1440, 810 and 390px) using real flex and grid layouts. You can download a Next.js App Router project (one route per page, plain CSS, no Tailwind or component library) or static HTML, or push to a branch of your own GitHub repository. There's no FNJ script or badge in the code, and FNJ doesn't host your site.
The limits are real. FNJ builds marketing sites only: no forms, store checkout, log-ins, databases or CMS. It has no free plan or trial.
Lovable
Lovable describes itself as an AI software engineer that builds websites and web apps from chat. Its docs say you own the code and can export it, migrate your data or self-host whenever you like. Git sync works on every plan; the ZIP download needs a paid plan. Apps created since May 2026 use TanStack Start, which runs server code, so they need a host that runs servers, not only static files. The database and uploaded files are exported separately.
Lovable is at its best when the project has log-ins and data. For a pure marketing site, you take on an app stack you may not need.
Bolt.new
Bolt builds apps and websites from chat, and its Bolt Cloud supplies hosting, databases and user authentication. Its help center explains how to download any project as a ZIP and run it locally with Node.js, and you can connect GitHub to back up the project and sync commits. Like Lovable, it shines when you need app features. The output is a JavaScript project, so plan on someone who's comfortable running npm.
v0 by Vercel
v0 turns prompts, screenshots or Figma designs into full-stack web apps built with Next.js, React, TypeScript, Tailwind CSS and shadcn/ui. Its FAQ says you can export the code and deploy elsewhere, and that Vercel doesn't own the code generated from your prompts. Publishing deploys to Vercel, and the full experience (previews, environment variables) assumes a connected Vercel project. If your team already works in Next.js on Vercel, v0 slots straight in.
Relume
Relume starts from a brief, builds a sitemap and wireframes, then assembles a marketing site from components its designers built and maintain, rather than writing fresh code. You can host with Relume or export to Webflow, Figma or React, where the React output uses Tailwind CSS and shadcn/ui. Its structure-first flow suits agencies that plan a site's pages before anyone argues about colors.
Builders with conditional export
Hostinger AI Builder
Hostinger's AI Builder has two modes. In agentic mode you can export a Node.js project built with React and Vite as a ZIP; to put it on plain static hosting you run a build first. Once exported, an edited project can't be imported back to keep prompting, and backend data stays with Hostinger. Manual mode exports content to WordPress only, without styles, layout, forms or SEO settings. Hosting, a domain and email come bundled, which is handy if you want one bill.
Webflow
Webflow's AI site builder turns a prompt into a site with its own design system, built on Webflow's Flowkit CSS framework. On paid Workspace plans (Site plans don't include it), code export gives you HTML, CSS, JavaScript and images in a ZIP, with no attribution required. CMS content, ecommerce, user accounts, password protection, form processing, site search and localized pages don't come along, and exported code can't be imported back. For a static marketing site, that's a genuine export. For a CMS-driven site, it isn't.
Builders that keep your site on their hosting
Framer
Framer's design canvas is excellent, and its AI agent (the old Wireframer page now redirects to it) generates editable pages, sections, copy and visuals, and can set up CMS collections. Hosting, CMS, SEO controls and analytics live in one platform. But Framer's help center says it does not offer HTML export for self-hosting, and that if you need to export source code, Framer may not be the right fit. A separate Framer help article on porting your data describes published sites as standard HTML you can move, so the docs aren't fully consistent; the dedicated export article is the clearer statement. If you already have a Framer site and want its code, a converter such as FNJ's own Framer to Next.js converter works from the published site, so you don't have to rebuild it.
Wix
Wix's AI builder goes from a prompt to a business-ready site, and you keep editing with drag and drop or its built-in AI agent, Aria. Business tools such as payment processing come wired in. Wix's help center says your site has to be hosted on Wix's servers because it runs on Wix's proprietary technology. Wix says the content you build belongs to you, and you can move your domain, but not the site itself.
Squarespace
Squarespace's Blueprint AI turns a description of your business into a multi-page site with pages, copy, imagery, colors and fonts, which you refine in its drag-and-drop editor. You need a paid plan to publish. Its export produces a WordPress-format XML file of certain content; style settings, custom CSS, store pages and several other page types don't export.
Durable
Durable is built for small-business owners who want a website plus a CRM, bookings and AI marketing help in one place. Hosting is included on every plan. Durable calls itself a no-code solution with limited HTML customization, and its own comparison page marks code export as unavailable. If you never plan to hire a developer or switch hosts, that trade may suit you fine.
How to choose
Work through these in order:
- Is it a marketing site or a product? If visitors need to log in, save data or pay inside the site, look at an app builder (Lovable, Bolt.new, v0) or a platform with those features built in. If it's pages that explain and convert, a design-first website builder is simpler to own.
- Who will maintain the code? A Next.js, React or Vite project needs someone comfortable with Node.js. Static HTML can be uploaded to almost any host.
- Where do you want to host? If you'd rather have one vendor for everything, a hosted platform (Framer, Wix, Squarespace, Durable) is less to think about. If you want to pick your host, choose a builder with a full export.
- What stays behind on export? Read the fine print for CMS content, forms, store, log-ins and translations. Those are the parts that usually don't travel.
- Can you test the exit before you commit? Export a small project, deploy it to a static host, and confirm it still runs with your builder account closed.

Where FNJ fits
If you need a marketing website and want to own the code from the first export, FNJ's builder is made for that job: design from references, then download Next.js or static HTML, or push to your GitHub repository, then host the HTML on Cloudflare Pages or any static host, or the Next.js project on a host such as Vercel or Netlify. If you need forms, a store or log-ins, link a dedicated tool from a button, or pick an app builder instead. See the details on the AI website builder with code export page and compare the credit plans.
Frequently asked questions
Can I export code from Framer?
Framer's help center states that it does not offer HTML export for self-hosting and that sites are hosted on Framer's platform. If owning the source code is a requirement, Framer's own documentation says it may not be the right tool for that workflow.
Does Webflow let you export your site's code?
Yes. On paid Workspace plans you can download your site's HTML, CSS, JavaScript and images as a ZIP and host it anywhere, but CMS content, ecommerce, user accounts, form processing and site search don't work on the exported site.
Which AI builders export a full codebase?
As of October 2026, FNJ, Lovable, Bolt.new and v0 let you download or sync a complete project you can host yourself, and Relume and Hostinger's AI Builder (agentic mode) export React code. Plans change, so confirm on each vendor's site before you commit.
Is an AI app builder or an AI website builder better for a marketing site?
For a site made of pages that explain and sell, a website builder is usually simpler, because you don't take on a database, authentication or server to maintain. App builders such as Lovable, Bolt.new and v0 fit better when visitors need to log in or save data.
Do I need a developer to host exported code?
Static HTML can be uploaded to most static hosts with no build step. Next.js, React and Vite projects need a build step, which a developer handles easily and a non-developer can learn by following the host's setup docs.
