How to Use WordPress as a Headless CMS in 2026 (Detailed Guide)

Headless WordPress is a great way to build a website that’s faster, safer, and more flexible than a traditional WordPress setup.

By separating the front end from the back end, you get complete control over how your site looks and performs—without giving up WordPress’s powerful content management features.

The best part? Setting up a headless WordPress website doesn’t have to be complicated or expensive.

In this guide, I’ll walk you through everything from deciding if headless WordPress is right for you to choosing the best tools and hosting options and setting it all up while keeping costs low.

Ready to get started? Let’s dive in!

What is Headless WordPress?

Headless WordPress is a way of using WordPress without its built-in front-end. Instead of relying on WordPress themes, you use the WordPress REST API or WPGraphQL to connect with modern front-end frameworks like React, Next.js, or Vue.js, and display content.

WordPress still manages the content, but a different technology controls how your users see it. This separation of the back-end (where content is created) from the front-end (where it is displayed) is what makes WordPress ‘headless.’

With headless WordPress, you get the best of both worlds: WordPress’s simple content management and the speed and flexibility of modern web technologies.

Since you no longer have to use a theme to display content, your website loads faster.

Modern front-end frameworks such as Next.js handle loading more efficiently with Server-Side Rendering which offers faster initial load times and improves the user experience.

Headless WordPress also offers greater flexibility. Unlike traditional WordPress, which is limited by themes, you can choose any front-end technology and even replace the entire front-end without changing the back-end.

Is Headless WordPress right for you?

Headless WordPress is a great choice if you need more speed, flexibility, and control over your website’s design and functionality. However, it’s not for everyone—it requires more technical knowledge and can be more complex to set up.

When headless WordPress makes sense

A headless setup is ideal if you:

1. Want a faster website with modern front-end technologies like React, Next.js, or Vue.js.
2. Need to publish content across multiple platforms, such as websites, mobile apps, or smart devices.
3. Have a highly customized website that wouldn’t work well within WordPress’s theme system.
4. Care about security and want to reduce the risk of attacks by keeping the front end separate from WordPress.

If any of these apply to you, headless WordPress could be a great solution for your website.

Potential drawbacks of Headless WordPress

Despite its advantages, headless WordPress isn’t always the best choice. Here’s why:

1. More Complex Setup: Unlike traditional WordPress, where everything is built-in, a headless setup requires configuring APIs, choosing a front-end framework, and setting up hosting separately.
2. Requires Development Skills: You (or your team) need knowledge of APIs, JavaScript frameworks, and front-end development. If you’re not comfortable coding, it can be a steep learning curve.
3. No Built-in Features Like Menus & Widgets: Since WordPress only handles content, you have to build navigation, layouts, and other features from scratch.
4. Higher Maintenance: With separate front-end and back-end systems, updates and troubleshooting can be more complex compared to a traditional WordPress site.

If you’re comfortable with these challenges and need the benefits of a headless setup, it could be the right choice for you. Otherwise, sticking with traditional WordPress might be the better option.

Steps to set up a headless WordPress website on a budget

Now, let’s look at how to set up a headless WordPress website using Cloudways for WordPress hosting and Vercel for front-end deployment.

We’re using that setup because it provides an affordable, secure, and high-performance solution without requiring deep technical expertise.

We’ll use Next.js as our front-end framework and a modified version of the Next-WP starter template, originally created by the awesome folks over at 9d8.

1. Install WordPress

First, you’ll need a hosting provider for your headless WordPress setup.

I’m using Cloudways because it’s affordable, fully managed, and takes care of security and maintenance for you. If you’re curious about their performance, check out my Cloudways review for a deeper dive.

Of course, Cloudways isn’t your only option. Other solid choices include Kinsta for premium managed hosting and Liquid Web if you need dedicated performance. If you’re still deciding, my guide on the best headless WordPress hosting compares the top providers to help you choose.

Signing up for Cloudways is easy. Just head to their signup page, create an account, and start your free 3-day trial—no credit card required.

If you use this link, you’ll get a flat 25% discount on the first two months of hosting when you upgrade to a paid account after the 3-day trial.

Once you’ve created an account, follow these steps to spin up your first Cloudways Flexible server:

• Create a server: Choose Servers from the top menu and select Add Server on the server management page.
• Enter application details: Select the application you want to install, such as WordPress, using the Select Application dropdown. Then, enter an Application Name, Server Name, and add it to a Project.
• Choose a hosting provider: You can only access DigitalOcean during the trial period. You can use Google Cloud and AWS once you upgrade to a paid account.
• Configure your server size: Choose your server size with the slider tool. A 1GB server should be enough for a basic website with a few hundred pages and posts.
• Select your server location: Use the dropdown to select a server location nearest to your customers.
• Launch the server: Click Launch Now and wait a few minutes for Cloudways to set everything up for you.

For a more detailed guide to spinning up your first Cloudways server, follow my Cloudways tutorial to get everything set up smoothly.

Once your server is ready, go to Applications > Access Details in your Cloudways dashboard.

All new Cloudways sites are assigned a default Cloudways subdomain. Select the Admin panel URL in the Access Details section.

Copy the username and password under the application URL and log in to your WordPress admin account.

Next, go to Settings > Permalinks and select Post Name for cleaner URLs.

2. Secure the WordPress REST API

The WordPress REST API is enabled by default, so you don’t need to activate it manually. But it’s good practice to restrict access to it when you’re using a headless WordPress setup.

We’ll do that by:

1. Restricting API access to logged-in users with a plugin.
2. Creating a dedicated application password for the front end using Application Passwords, a built-in feature in WordPress.

First, go to Plugins > Add New Plugin and search for “Disable WP REST API”. Click Install Now and Activate once the installation is complete.

This plugin will automatically restrict REST API access for users who are not logged in, making your site more secure. You don’t need to configure anything manually.

Next, go to Users > Profile in the WordPress admin and scroll to the Application Passwords section.

Enter a name for the application (e.g., “Headless Frontend”) and click Add New Application Password.

Copy the generated password immediately and save it because it won’t be displayed again.

That password allows authenticated requests to your REST API without exposing your main account credentials.

3. Deploy the frontend with Vercel

Vercel is a serverless hosting platform that integrates perfectly with Next.js. It also offers a free plan, making it an excellent choice for launching your headless WordPress site without upfront costs.

Getting started with Vercel is easy.

Sign up at Vercel using your email address or GitHub account, or if you already have an account, log in to your Vercel dashboard.

Then, click the below deploy button to clone and deploy the Next-WP template.

If you’ve signed up with your email, you’ll need to connect a Git account before proceeding.

Connect your GitHub account and click Create to deploy the template.

Next, you’ll need to add the following values:

Finally, click Deploy and wait a few seconds for Vercel to deploy your Next.js application.

4. Configure WordPress to handle automatic cache revalidation

Now that we’ve set up Next.js on Vercel and secured our WordPress REST API, the next step is ensuring that our front end automatically updates whenever we change content in WordPress.

By default, Next.js caches API requests for performance. This means that if you update a post in WordPress, your front end won’t immediately reflect the change until the cache expires.

To solve that problem, we’ll set up automatic cache revalidation by manually adding a function to WordPress.

The best way to edit the functions.php file is to use a child theme. If you don’t have one, check out my tutorial on how to create a WordPress child theme.

Open your child theme’s functions.php file in an editor. You can do this in a few different ways, including:

1. The WordPress Theme File Editor.
2. Editing the file over SFTP.

Paste the following code into the file and save it:

function trigger_nextjs_revalidate($post_id) {
    $post = get_post($post_id);
    if (!$post) return;

    $post_slug = get_permalink($post_id); // Get post URL
    $path = str_replace(home_url(), '', $post_slug); // Convert URL to path

    $url = 'https://your-vercel-site.vercel.app/api/revalidate?secret=YOUR_WEBHOOK_SECRET&path=' . urlencode($path);
    wp_remote_post($url, [
        'method'    => 'POST',
        'headers'   => ['Content-Type' => 'application/json'],
    ]);
}
add_action('save_post', 'trigger_nextjs_revalidate');

• Replace the your-vercel-site.vercel.app placeholder with your actual Vercel domain.
• Replace the YOUR_WEBHOOK_SECRET placeholder with the same secret key used in Vercel’s environment variables.

Finally, test cache revalidation is working by either visiting the revalidation webhook URL in your browser by editing or publishing a post in WordPress and opening the Next.js frontend to check if the changes reflect immediately.

5. Customize your site and go live

The Next-WP template is designed to be flexible, allowing you to customize the look and functionality to match your business needs.

Here are a few ways to make it your own:

• Update styling:
  • Modify the Tailwind CSS styles in styles/global.css to match your brand.
  • Adjust layout components like the Header.js and Footer.js to reflect your branding.
• Add custom pages:
  • If you need additional pages, create new .js files inside the pages/ directory.
  • Fetch WordPress content dynamically based on custom post types.
• Improve SEO:
  • Use the next-seo package to improve metadata and social sharing previews.
  • Optimize images with the built-in Next.js <Image> component.
• Add ecommerce features:
  • If you plan to sell products, integrate WooCommerce’s REST API with Next.js.
  • Build a cart system using Next.js’s built-in API routes.

Since your Vercel app is currently running on the free your-vercel-project.vercel.app domain, you need to point it to your custom domain (yourdomain.com) before you can go live.

Go to your Vercel dashboard and select the headless Next.js project you just created.

Navigate to Settings > Domains and click Add.

Enter your domain name or subdomain exactly as you want it to load in a browser, for instance, example.com, www.example.com, or blog.example.com.

Vercel will then show the IP address you need to set up with your DNS provider.

Then, go to your domain registrar (GoDaddy, Namecheap, Cloudflare, etc.) and add the following DNS records based on what Vercel provides:

• Type: A
• Name: @ (or blog if using a subdomain)
• Value: IP address shown in your Vercel dashboard.

If you’re using Cloudflare, like me, make sure the proxy setting is disabled (click the cloud icon and turn it gray to set it to “DNS only”).

Now that your front end is moving to your custom domain, update your .env.local to ensure internal links and API requests work correctly.

Go back to your Vercel dashboard and navigate to Project > Settings > Environment Variables.

Enter NEXT_PUBLIC_SITE_URL in the Key field and enter your domain, including the protocol in the Value field, for example, https://yourdomain.com.

Click Save and then redeploy your project.

That’s it! Your headless WordPress website will now load on your custom domain.
