Using headless WordPress to build a website with Lovable

Artificial intelligence, improved development tooling, and modern hosting environments are giving headless WordPress a fresh wave of attention among designers and developers. This evolution is shaping how distributed digital experiences are designed, built, and deployed.

In this walkthrough, we explore how to use Lovable, an AI-driven frontend builder, to create a modern website powered by a headless WordPress backend.

What we’re seeing today offers a glimpse into the future of WordPress, whether headless or traditional: a more open, collaborative, and AI-assisted approach to creating digital experiences that blend content management with creative design freedom.

Understanding headless WordPress

Setting up a headless WordPress environment is simpler than it sounds. Think of it as splitting WordPress into two parts:

• Backend – WordPress continues to manage your content, media, and data as usual.
• Frontend – A separate app handles how everything looks and behaves.

By separating the two, you keep WordPress’s reliable content management while gaining the freedom to design and build with modern frontend frameworks like React or Vue. It’s about taking the best of WordPress and extending it beyond what a traditional setup can do.

Another way to picture it: WordPress handles the structure (your content), and your frontend handles the style (how it’s presented).

Why Lovable?

Is headless WordPress really necessary? That depends on your goals. For many projects, a standard WordPress setup is still the easiest and most efficient path. However, if you want more flexibility, faster iterations, or a way to build modern web apps that go beyond traditional themes and plugins, headless WordPress starts to shine.

For this project, we used Lovable, an AI-powered development platform that helps you generate, edit, and manage frontend code. It builds with modern tools like React, Tailwind CSS, and Vite, and uses AI prompts to handle layout, styling, and component logic.

In other words, Lovable isn’t the frontend itself. It’s the environment where the frontend is created and maintained.

Here’s what made it a good fit for our experiment:

• Version control flexibility: easy 2-way sync with GitHub, GitLab, or Bitbucket.
• Cross-platform design: build for web, mobile, or kiosk displays from a single WordPress backend.
• Instant iterations: update layouts, styles, or components in seconds using AI prompts.
• Decoupled security: no direct database exposure from the frontend side.
• Supports static builds: easily deploy as static HTML, CSS, and JavaScript for better performance and reliability.

Of course, headless setups aren’t without trade-offs. Maintaining a multi-layer stack can make debugging more complex, and plugins that render content on the frontend may require custom API bridges. Still, for static or content-driven sites, pairing WordPress with Lovable offers a fast, modern way to explore what headless can do.

Getting started

Before building, let’s set up the two main parts of our stack: Lovable for the frontend and WordPress for the backend.

Step 1: Create a Lovable project

Head to lovable.dev and create a free account. Once you’re on the dashboard, start a new project by entering a short prompt.

The chat interface makes it feel like you’re talking to a teammate. You can type naturally, just as you would in a real conversation. For example, you might begin with a simple question:

How do we start building a frontend with WordPress on the backend?

Lovable responds with clear guidance, walking you through your options:

Building a React frontend with WordPress as a headless CMS is a solid approach.
You can use the built-in WordPress REST API or install WPGraphQL for more complex data queries.

This first exchange sets the tone for the process. It provides a quick overview of what’s possible and helps you understand how WordPress will integrate with your frontend.

You can then refine the idea by prompting the AI to keep things simple:

Let's keep it simple. We just want to build a demo blog site and have a page to serve as a dynamic style guide.

Lovable adapts right away, creating a clean demo site and setting up a Style Guide page you’ll use later for global design updates.

From here, the conversation flows naturally. You and Lovable go back and forth refining details and clarifying what’s needed to move ahead. At some point, Lovable may ask you for essential setup details such as:

1. Do you have a WordPress site URL? (e.g., https://yoursite.com)  
2. Is the WordPress REST API publicly accessible?  
3. What WordPress content should map to your blog? (posts, pages, or custom post types?)  
4. Are there custom fields you’d like to fetch? (e.g., read time or featured flag)

Once you provide this information, Lovable can automatically generate the integration logic, connecting your frontend with your WordPress backend.

Step 2: Set up WordPress

Before Lovable can pull in real content, you need a working WordPress site to serve as your backend. This is where all your posts, pages, and media live.

For a smooth setup, use a reliable WordPress host like Kinsta, built on a powerful cloud infrastructure to make sure performance and uptime aren’t an issue. Sign up on Kinsta and create a new WordPress site, and you automatically get a temporary subdomain like:

https://your-site.kinsta.cloud/

Once your site is created, check that the REST API is publicly available. Open a new browser tab and visit:

https://your-site.kinsta.cloud/wp-json/wp/v2/posts

If you see a JSON feed displaying post data, your backend is ready.

Step 3: Connect WordPress to Lovable

Once your WordPress site is live and your REST API is working, it’s time to connect the backend to your Lovable project. This is where the content and design finally come together.

In Lovable’s chat, you can simply ask:

Ok, how do we connect your frontend to our WordPress CMS?

Lovable replies with a clear plan, explaining what’s needed:

You’ll connect to your WordPress backend using its REST API.
What you’ll need:
1. WordPress REST API (built-in, available at yoursite.com/wp-json/wp/v2/posts)
2. A CORS plugin if your frontend is on a different domain
3. (Optional) ACF or custom fields for extra data

It also gives you an overview of what happens on both sides:

• On the WordPress side: make sure the REST API is enabled (it usually is by default).
• On the frontend: replace any static blog data with API calls to WordPress, create a service to fetch the data, and handle loading states.

You see Lovable outline it neatly, sometimes even showing you an example like this:

const { data: posts } = useQuery({
  queryKey: ['posts'],
  queryFn: async () => {
    const response = await fetch('https://your-site.kinsta.cloud/wp-json/wp/v2/posts');
    return response.json();
  }
});

Next, Lovable, at your command, uses the WordPress URL you provide and sets up a frontend site that displays your WordPress posts.

It’s that quick. The integration is live, the connection has been verified, and your headless site now has a fully functioning content flow from WordPress to Lovable.

Styling and design system

Once your WordPress connection is live, you can start refining the site’s look and feel. At this point, everything you see is styled by Tailwind CSS and the browser’s default settings. That gives you a clean foundation, but now it’s time to make it yours.

You can begin by asking Lovable directly:

Is all styling currently provided by TailwindCSS and the User Agent?

Lovable explains:

Yes. All styling is currently provided by TailwindCSS (via index.css and tailwind.config.ts) and the User Agent's default styles. The App.css file exists but isn’t imported anywhere.

With that in mind, you can start customizing the site’s structure and navigation. For example, you could prompt:

Connect to all pages, posts, and media, and set up a header navigation as follows:
Home
Style Guide
Blog
    Trip To Santa Fe
    Hello World
Make the Home page the root of the site.

Lovable responds by reorganizing your routes and dynamically linking your WordPress posts under the Blog dropdown. Navigation now works across pages: Home, Blog, and your Dynamic Style Guide, which becomes your hub for global design changes.

Working with the dynamic style guide

This page is where you define and control global styling across your entire site. Any change you make here updates all pages instantly.

You might begin by setting a base color palette and typography:

Set page background color to #7B3F00.
Set all text color to #eee.
Heading 1 = 2rem
Heading 2 = 1.5rem
Heading 3 = 1.25rem
Heading 4 = 0.84375rem
All other text = 1rem

Lovable quickly applies the new design system, giving your site a warm brown background, soft gray text, and consistent type hierarchy.

From here, you can continue refining your approach. For example:

Double the size of all headings.
Add 10% left and right margin to the page.
Create a 2x2 image gallery with 20px spacing, rounded corners (20px radius), and a 2px solid white border.

Lovable adjusts the layout in real time, and you see your image gallery form immediately.

Global font and spacing adjustments

You can take your design a step further by applying consistent fonts and spacing rules site-wide:

Align the page title to the left.
Use the Cowboy (Rye) font for all headings and Roboto for all other text.
Double the line height for all paragraphs and quote elements.
Add 5% top/bottom and 10% left/right margins to the quote block.

Lovable updates your typography, line heights, and margins.

If something looks off, for instance, if the title isn’t truly left-aligned, you can ask Lovable to check:

The page title isn’t aligned left. Why?

And it will explain:

The container has mx-auto, which centers it. I’ll remove that for true left alignment.

Defining global button styles

Next, you can bring visual consistency to your buttons. In your Dynamic Style Guide, prompt Lovable to create three button sizes with clear hover states:

1. Buttons should be rectangular.
2. Use a black background with white text, and invert on hover.
3. The medium button is 125% the width of the small one; the large is 150%.
4. Add 20px border radius.

If you don’t see the buttons right away, Lovable can add a showcase section to preview them. Once visible, it applies your custom styles.

Here’s an example of the resulting CSS you can also use in WordPress:

.wp-button {
  background: #000;
  color: #fff;
  border-radius: 20px;
  padding: 0.5rem 0.9375rem;
  transition: all 0.3s ease;
}

.wp-button:hover {
  background: #fff;
  color: #000;
}

.wp-button-sm { width: 100%; }
.wp-button-md { width: 125%; }
.wp-button-lg { width: 150%; }

Lovable also explains how to bring these styles into your WordPress theme by copying the variables into your theme’s CSS and applying the .wp-button classes within the block editor or templates.

Deployment

With your headless site connected and styled, the final step is deployment, which involves getting it live on the web.

Lovable’s codebase is portable, which means you can push your frontend to any Git-based platform and deploy from there. In this guide, we’ll use Sevalla, a platform built by the Kinsta team that combines powerful cloud hosting with developer-friendly automation.

Sevalla offers free static site hosting, with global edge delivery and auto-deploys on Git push. Once your code is synced to GitHub, GitLab, or Bitbucket, you can connect your repository to Sevalla in just a few clicks.

Here’s how to go live:

1. In your Sevalla dashboard, go to Static Sites and click Add site.
2. Choose your Git provider and repository.
3. Confirm your default branch and enable automatic deployment on commit.
4. Sevalla detects your framework automatically (React + Vite in this case).
5. Click Create site, and your build starts right away.

Within a few minutes, your site will be available with a free temporary domain.

Helpful tips and other observations

As you work through your headless build with Lovable, a few things stand out that make the process smoother and easier to understand.

• Free and paid plans: Lovable offers both. The free plan gives you plenty of room to experiment, while the paid tiers provide longer prompt sessions and faster processing.
• No need to refresh often: In most cases, Lovable’s interface updates automatically when you change or publish content from WordPress. The live sync is fast and reliable.
• Direct file editing: Like GitHub, Lovable lets you edit files directly inside the platform. It’s handy for quick adjustments or debugging small issues without switching to an external editor.
• REST API vs. WPGraphQL: For most simple projects, the built-in WordPress REST API is enough. However, if you require more complex queries or relationships, the WPGraphQL plugin provides a more powerful and structured option.
• Common setup issues: If you encounter connection problems, they’re often related to CORS (Cross-Origin Resource Sharing) or REST API access permissions. Lovable’s AI Agent can help walk you through these quickly.
• Caching considerations: Because your frontend is static, changes may not appear immediately during development. Clear your cache or rebuild when you make major updates.

Summary

Headless WordPress opens up a space where design and development meet with almost no limits. By combining WordPress as a dependable content backend with Lovable’s AI-driven frontend creation, you can move from concept to live deployment faster than ever.

As AI continues to shape workflows, headless WordPress emerges as a flexible, future-ready approach for creators seeking speed, control, and freedom in equal measure.
