WordPress Playground

Run WordPress entirely in the browser using WebAssembly. Ephemeral instances with SQLite, perfect for demos, testing, and quick prototyping.

Quick Start

Local Development Server

npx @wp-playground/cli@latest server --auto-mount

This starts a local Playground instance, auto-mounts your plugin/theme, and provides hot reload.

Browser-Based

Visit playground.wordpress.net for instant WordPress.

Blueprint Files

Blueprints automate Playground setup — install plugins, themes, configure settings.

Basic Blueprint

{
    "$schema": "https://playground.wordpress.net/blueprint-schema.json",
    "landingPage": "/wp-admin/",

        {
            "step": "installPlugin",
            "pluginData": {
                "resource": "wordpress.org/plugins",
                "slug": "gutenberg"
            }
        },

        }
    ]
}

Testing Matrix

Test across PHP/WP versions without local infrastructure:

    }
}

Key Characteristics

• Ephemeral — data doesn't persist by default
• SQLite-backed — not MySQL (some queries may differ)
• Sandboxed — safe for experimentation
• No external network — HTTP requests are limited
