Featured blueprints

Art Gallery, Coffee Shop, Feed Reader with the Friends Plugin, Gaming News, and Non-profit Organization are shown first; the full 43-card gallery follows.

Unsaved session consequence

The active site is still only in memory. Saving changes the identity and adds it to Your Playgrounds.

Client demo - local

Saved today at 10:25 UTC. WordPress 7.0, PHP 8.3.

Woo checkout test

Saved yesterday. Coffee Shop blueprint with WooCommerce sample products.

Theme PR repro

Gutenberg trunk, Twenty Twenty-Five, debug logging enabled.

This is an Unsaved Playground

Your changes will be lost on page refresh unless the site is saved locally.

Runtime settings

WordPress Version PHP Version Language Allow network access Create a multisite network

Destructive reset ledger

Applying runtime settings replaces the running WordPress site. The confirmation shows before/after identity, supports cancel, requires a typed phrase, then shows progress and a completed state.

/wordpress

wp-admin

wp-content

wp-includes

index.php

wp-config.php

wp-cron.php

wp-login.php

<?php define('CONCATENATE_SCRIPTS', false);

/** The base configuration for WordPress */
define('DB_NAME', 'database_name_here');
define('DB_USER', 'username_here');
define('DB_PASSWORD', 'password_here');
define('DB_HOST', 'localhost');

if ( ! defined( 'ABSPATH' ) ) {
  define( 'ABSPATH', __DIR__ . '/' );
}

Database management is an early access feature
