WordPress Backup, Restore, Staging, Cloning & Migration — All in One
WP STAGING is the all-in-one WordPress backup, restore, staging, cloning, and migration plugin, built for professional workflows with 100% unit-tested code, thousands of automated tests, and extensive end-to-end testing across supported PHP versions.
Create a full backup or an exact clone or copy of your website in minutes. Use it to duplicate your site, test plugin and theme updates safely, restore your site when needed, move or migrate WordPress to another server, transfer your site to a new host, or build a staging copy before making changes. WP STAGING also works as a WordPress duplicator, so you do not need a separate duplicator plugin to copy your website.
WP STAGING reliably backs up, clones, and migrates WooCommerce stores too, including orders, products, and customer data.
WP STAGING is developed in Germany and designed for agencies, developers, and businesses that need reliable WordPress backup, recovery, staging, restore, and migration workflows.
WP STAGING | PRO also includes advanced workflows such as Remote Sync, which lets you pull a WordPress site securely from one server to another using an API key, and WP STAGING CLI, which can turn a WP STAGING backup into a local Docker-based development site.
