How to Use WordPress Playground

As WordPress developers, we’ve all been there—struggling to set up local environments, battling compatibility issues across different versions, and trying to share our work with clients for feedback. What if there was a tool that could eliminate these pain points and revolutionize your WordPress development workflow?

Enter WordPress Playground—a game-changing browser-based solution that’s transforming how developers build, test, and showcase WordPress plugins and themes. Having recently presented this topic at a WordPress meetup, I want to share why this powerful tool deserves a place in every WordPress developer’s toolkit.

What is WordPress Playground?

WordPress Playground is a browser-based environment that lets you run a fully functional WordPress installation directly in your web browser—no server setup required. This groundbreaking technology compiles WordPress (originally written in PHP) to WebAssembly, allowing it to run entirely client-side in your browser.

The key benefits that make WordPress Playground stand out:

• Browser-based: No need for local server setup or complex environments
• Instant setup: Run WordPress with a single click in seconds
• Isolated testing: Perfect for testing plugins and themes without conflicts
• Version flexibility: Test across multiple WordPress and PHP versions effortlessly
• Highly shareable: Easily share your work with clients or team members via URL

The Traditional Development Cycle vs. WordPress Playground

To understand the transformative impact of WordPress Playground, let’s compare it to the traditional WordPress development workflow:

Traditional Development Cycle:

1. Setting up local environments (XAMPP, Local, Docker, etc.)
2. Testing across multiple WordPress versions (requiring multiple installations)
3. Dealing with compatibility testing challenges
4. Collecting feedback from clients (requiring staging servers or sharing access)

This approach is time-consuming, resource-intensive, and often creates barriers to efficient testing and collaboration.

With WordPress Playground:

1. Instant testing environment with zero setup
2. Test across multiple WordPress versions with a simple URL parameter change
3. Complete isolation ensures no plugin conflicts
4. Share work instantly with clients via a simple URL
5. Allow potential users to test your plugins without installation

The difference is dramatic—tasks that once took hours now take seconds, and processes that required technical knowledge from all participants now need just a browser.

The interface is intuitive—you’ll see a WordPress installation running in your browser instantly. You can log in to the admin dashboard, install plugins, customize themes, and do virtually anything you’d do with a regular WordPress installation.

WordPress Playground APIs: Powerful Tools for Developers

What makes WordPress Playground especially valuable for developers are its powerful APIs that allow for customization and integration:

Query API

The Query API lets you define your WordPress Playground environment through URL parameters. For example:

https://playground.wordpress.net/?theme=pendant&php=8.0&wp=6.6&plugin=contact-form-7&url=/wp-admin/admin.php?page=wpcf7

This URL creates a Playground with:

• The Pendant theme
• PHP 8.0
• WordPress 6.6
• Contact Form 7 plugin installed
• Opens directly to the Contact Form 7 admin page

This powerful feature allows you to create specific testing environments or demo setups that can be shared with a simple link.

Blueprints

Blueprints take customization even further by allowing you to define a sequence of actions to set up your WordPress environment. This is done using a JSON configuration that can:

• Install specific plugins and themes
• Import content
• Configure settings
• Set up user accounts
• And much more

Here’s a simplified example of a blueprint:

{
  "steps": [
    {
      "step": "installPlugin",
      "pluginData": {
        "resource": "wordpress.org/plugins",
        "slug": "coblocks"
      }
    },
    {
      "step": "installTheme",
      "themeData": {
        "resource": "wordpress.org/themes",
        "slug": "pendant"
      }
    }
  ]
}

Blueprints can be hosted on GitHub or other platforms and referenced via URL, making them perfect for creating consistent demo environments.

JavaScript API

For more advanced use cases, the JavaScript API gives you programmatic control over your WordPress Playground instance, allowing integration into your own applications or websites.

Real-World Applications for WordPress Developers

How can you use WordPress Playground in your daily work? Here are some practical applications:

1. Plugin and Theme Development Testing

Test your plugins and themes across multiple WordPress versions without maintaining multiple local installations. This is invaluable for ensuring compatibility and catching issues early.

2. Client Demos and Approval

Create a pre-configured demo of your plugin or theme and share it with clients via a simple URL. Clients can interact with your work without needing to install anything, streamlining the approval process.

3. Adding “Live Preview” to Your Plugin

Give potential users the ability to try your plugin before installing it. By adding a “Try in Playground” button to your plugin page, you can significantly increase user confidence and adoption rates.

4. Translation Testing

For multilingual plugins, WordPress Playground provides an easy way to test translations in context. For example:

https://translate.wordpress.org/projects/wp-plugins/your-plugin/dev/hi/default/playground

5. Documentation and Tutorials

Create interactive tutorials for your plugin or theme where users can follow along in a real WordPress environment, making your documentation more effective and engaging.

Adding WordPress Playground to Your Own Projects

To leverage WordPress Playground in your own projects, you have several options:

Direct URL

The simplest approach is to link to a pre-configured Playground instance:

https://playground.wordpress.net/?plugin=your-plugin

Blueprint URL

For more complex setups, create a blueprint JSON file and host it on GitHub or your server:

https://playground.wordpress.net/?blueprinturl=https://your-site.com/blueprints/your-blueprint.json

iframe Embedding

Embed a WordPress Playground directly in your website:

<iframe 
  src="https://playground.wordpress.net/?theme=pendant&plugin=your-plugin" 
  width="100%" 
  height="800px" 
  allow="clipboard-write">
</iframe>

WordPress Playground Block

If you’re using WordPress for your documentation or marketing site, you can use the Interactive Code Block plugin to embed Playground instances directly in your posts.

Creating a Blueprint for Your Plugin

To create a blueprint for your plugin, follow these steps:

1. Visit the Blueprint Builder
2. Configure your desired WordPress setup
3. Add installation steps for your plugin
4. Add any additional configuration steps
5. Save and host your blueprint JSON file

Here’s what a basic blueprint looks like:

{
  "steps": [
    {
      "step": "installPlugin",
      "pluginData": {
        "resource": "url",
        "url": "https://your-site.com/your-plugin.zip"
      }
    },
    {
      "step": "installTheme",
      "themeData": {
        "resource": "wordpress.org/themes",
        "slug": "twentytwentyfour"
      }
    },
    {
      "step": "setSiteOptions",
      "options": {
        "blogname": "Your Plugin Demo"
      }
    }
  ]
}

Best Practices for Using WordPress Playground

To get the most out of WordPress Playground, consider these best practices:
