Blueprint data Format

A Blueprint can contain the following properties:

  • landingPage (string): The URL to navigate to after the Blueprint has been run.
  • preferredVersions: The preferred PHP and WordPress versions to use.
  • steps: The steps to run.

Here's a Blueprint that uses all of them:

"landingPage": "/wp-admin/",
"preferredVersions": {
"php": "7.4",
"wp": "6.5"
"phpExtensionBundles": [
"features": {
"networking": true
"steps": [
"step": "login",
"username": "admin",
"password": "password"

JSON Schema

JSON files can be tedious to write and easy to get wrong. To help with that, Playground provides a JSON schema file that you can use to get autocompletion and validation in your editor:

"$schema": "",
"landingPage": "/wp-admin/",
// ...

Preferred Versions

The preferredVersions property, unsurprisingly, declares the preferred of PHP and WordPress versions to use. It can contain the following properties:

  • php (string): The preferred PHP version to use. Defaults to "latest". Only accepts major versions, like "7.4" or "8.0". Minor versions like "7.4.1" are not supported.
  • wp (string): Loads the specified WordPress version. Supported values: The last three major WordPress versions—minor versions, like 6.5.1, are not supported. As of April 4, 2024, that's 6.3, 6.4, 6.5. You can also use these values: latest (default), nightly, or beta.

PHP extensions

The phpExtensionBundles property is an array of PHP extension bundles to load. The following bundles are supported:


The features property is used to enable or disable certain features of the Playground. It can contain the following properties:

  • networking: Defaults to false. Enables or disables the networking support for Playground. If enabled, wp_safe_remote_get and similar WordPress functions will actually use fetch() to make HTTP requests. If disabled, they will immediately fail instead.
