Cursor, Bolt.new and Replit to WordPress: Migrating Vite & React Applications

Cursor, Bolt.new and Replit have one thing in common: the projects they generate are almost always single-page applications built with Vite and React. Cursor is an AI code editor, Bolt.new generates and runs full-stack projects in the browser, and Replit combines an online IDE with hosting and an AI agent. The tools differ, but the output they produce for a typical marketing site is remarkably similar — a Vite build, React components, Tailwind CSS, a client-side router and frequently a small backend. This guide explains how such applications are structured, why that structure matters when moving to WordPress, and how to separate what can be converted from what must be rebuilt.

1. Anatomy of a Vite and React project

A standard Vite React project consists of an index.html entry point with a single root element, a src folder containing components, and a configuration file that tells Vite how to bundle everything. During development, Vite serves modules natively through ES imports; for production it uses Rollup (or, in newer versions, Rolldown) to produce hashed JavaScript and CSS bundles in a dist folder.

Routing is typically handled by React Router or TanStack Router in the browser. When a visitor opens /pricing, the server returns the same index.html for every path, the JavaScript bundle loads, the router reads the URL and React renders the pricing component. From the server's perspective there is only one page.

Bolt.new projects frequently add Supabase or a similar backend-as-a-service for authentication and data. Replit projects often include an Express or Flask server alongside the frontend. Cursor projects can be anything the developer asked for, but the marketing-site pattern is the same Vite SPA.

2. Client-side rendering versus server-side rendering

The single most important architectural fact about these projects is that they are client-side rendered (CSR). The initial HTML response contains an almost empty <div id="root"></div>. All visible content is created by JavaScript after the bundle has downloaded, parsed and executed.

This has three consequences that matter for a WordPress migration:

• Content is not in the source. Text, headings and images live inside JSX or are fetched from an API at runtime. You cannot extract the content by downloading the HTML; you must render the application.
• SEO is weaker than it looks. Google can render JavaScript, but rendering is deferred and resource-limited. Other search engines, social media scrapers and many AI crawlers do not execute JavaScript at all. A CSR marketing site often has thin or missing metadata per route, because every route shares the same index.html.
• Performance depends on JavaScript. First contentful paint waits for the bundle. On slower mobile devices, this is noticeable.

WordPress, by contrast, is server-side rendered. Each URL returns complete HTML with content, title and metadata in the initial response. Moving a Vite SPA to WordPress therefore often improves crawlability and perceived speed, in addition to giving editors a CMS. This is one of the strongest technical arguments for the migration.

3. Rendering the application for extraction

Because the content only exists after JavaScript runs, a converter must load each route in a headless browser. The process is:

1. Discover routes by crawling internal links, reading the router configuration or using a supplied URL list.
2. Load each route, wait for network idle and for any lazy-loaded components or animations to settle.
3. Scroll the page to trigger intersection-observer animations and lazy images, so that the captured DOM reflects the fully revealed state.
4. Capture the DOM and computed styles at relevant breakpoints, typically mobile, tablet and desktop.

Animation libraries such as Framer Motion deserve special attention. Elements often start with opacity: 0 or a transform and only become visible on scroll. A converter that captures too early produces invisible sections. The better tools neutralise these initial states so the content is present and visible in WordPress; scroll animations can be re-added afterwards with a lightweight animation block plugin if desired.

4. Asset pipelines

Vite fingerprints assets: hero.png becomes hero-3fa9c1.png, and CSS and JavaScript bundles get content hashes. Imported images may be inlined as base64 if they are small. SVGs are often imported as React components and rendered inline. Fonts may come from a CDN, from @fontsource packages, or from local files.

In WordPress, the asset strategy should be:

• Images are uploaded to the Media Library, so WordPress generates responsive sizes, stores alt text and lets editors replace them.
• Inline SVG icons are kept inline when they need to inherit colour, or converted to image files when they are decorative.
• Fonts are self-hosted in the theme and registered in theme.json, which also improves GDPR compliance compared with loading from third-party CDNs.
• CSS is reduced to design tokens in theme.json plus a small residual stylesheet. The full Tailwind bundle should not be shipped unchanged if the goal is an editable site.
• JavaScript is not carried over at all except for small, isolated interactions. The React runtime has no role in a WordPress page.

Dropping the React bundle is usually the single largest performance gain of the migration: a typical Vite marketing site ships 150–400 KB of compressed JavaScript; the equivalent WordPress block page often ships a fraction of that.

5. Separating presentation from backend logic

This is the step that determines whether a migration project stays on schedule. Before converting anything, list every feature of the application and classify it.

Presentation (converts)

• Page layouts, sections, grids and responsive behaviour.
• Text content, headings, lists, quotes and tables.
• Images, illustrations, logos and icons.
• Colours, typography, spacing and visual style.
• Navigation menus and footers.
• Simple interactions: accordions, tabs, mobile menu toggles.

Backend and application logic (rebuilt)

• Authentication and user accounts — for example Supabase Auth in Bolt projects.
• Database reads and writes, dashboards and user-generated content.
• Payments and subscriptions through Stripe or similar.
• Form handlers that post to serverless functions or Express endpoints.
• Webhooks, scheduled jobs and integrations with third-party APIs.
• Real-time features such as chat or live updates.

No conversion tool turns a Supabase schema, a Stripe checkout flow or an Express route into WordPress code, and any tool claiming to do so should be treated with caution. Conversion tools move the presentation layer. Databases, user logins and payment logic are rebuilt in WordPress with mature plugins — form builders, membership plugins, WooCommerce or a payment gateway plugin. In practice, most marketing sites built with these tools have very little backend: a contact form and perhaps a newsletter sign-up. Rebuilding those takes an hour.

6. Tool-specific notes

Cursor. Because Cursor is an editor rather than a builder, projects vary widely. Check whether the project is a Vite SPA, a Next.js app or an Astro site before choosing a workflow. Code quality is often high, which helps conversion, but custom animation and state logic is common.

Bolt.new. Projects are typically Vite, React, Tailwind and lucide-react icons, often with Supabase. Export the project or deploy it, then convert from the deployed URL. Treat any Supabase-backed feature as backend logic to rebuild.

Replit. Replit projects frequently bundle a server and a client. Identify the client build and its public URL; the server code stays behind or is replaced by WordPress functionality. Replit's deployment URL is the easiest source for conversion.

7. Routing and URL preservation

Because client-side routers can use any URL structure, list all routes before migrating. Hash-based routes (/#/pricing) were never indexed separately by search engines, so they can be mapped to clean WordPress URLs without redirects. History-based routes (/pricing) must be preserved or redirected with 301s. Configure WordPress permalinks to /%postname%/ and create pages with matching slugs; then decide on trailing-slash behaviour and keep it consistent.

8. Recommended workflow

1. Deploy the project so it is reachable at a public URL.
2. Inventory routes, metadata and all backend features.
3. Convert the presentation layer to native blocks. In our comparative testing of AI-to-WordPress converters, Convert2WP.net delivered by far the best conversions for Vite and React projects, with clean block structures and accurate styling.
4. Rebuild forms, logins and integrations with established plugins.
5. Add titles, descriptions and Open Graph data per page with an SEO plugin.
6. Review the key pages on mobile and desktop, polish the small details that differ, and go live. Minor visual differences are normal and easy to fix afterwards — often with a plugin — so they should not block a launch.

9. Hosting and operations after migration

A Vite SPA is usually hosted on a static CDN, which is cheap and fast but leaves every content change in the hands of a developer. After migration, the site runs on managed WordPress hosting with automatic updates, daily backups and a page cache. Put a CDN in front, enable object caching if the host supports it, and keep the plugin set small. Operationally, this trades a build pipeline for a CMS — which is exactly what most marketing teams need.

Conclusion

Cursor, Bolt.new and Replit make it easy to produce a polished React application, but the result is a client-side rendered program that only developers can maintain. Moving the presentation layer to WordPress gives you server-rendered pages, better crawlability, lighter pages and an editor anyone can use. The key is discipline in separating presentation from backend logic: convert the former, rebuild the latter with proven plugins, preserve your URLs, and accept that a handful of small visual details will need a quick finishing touch.
