Description

NS Cloner is a WordPress site cloner and site duplicator built for WordPress Multisite networks. It lets you clone an existing multisite subsite into a new site with the same content, media, theme settings, plugin settings, menus, widgets, posts, pages, custom post types, taxonomies, and site configuration.
Instead of rebuilding the same WordPress site setup manually, NS Cloner copies a fully configured source site and creates a new duplicate site inside your multisite network. It automatically updates the new site name, title, URLs, and other background references so the cloned site works like a clean, properly configured WordPress site.
NS Cloner is ideal for developers, agencies, designers, schools, franchises, membership organizations, SaaS-style WordPress platforms, and teams that need to duplicate WordPress multisite subsites quickly and reliably.
Important: the free version of NS Cloner is for WordPress Multisite only. It works from the WordPress Network Admin dashboard. If you need to clone a single WordPress site, clone between single-site and multisite installs, or copy a site to a remote WordPress install, WP Site Cloner Pro adds those capabilities.

Standard Precautions

NS Cloner works at the database level to duplicate WordPress sites inside a multisite network. It has been used on production systems for years, but you should still test it in your own environment before using it on a critical network. Always back up your data before cloning, duplicating, or making large database-level changes to any WordPress site.

FAQ

Can I clone a WordPress site with NS Cloner?: Yes, but the free version is specifically for cloning sites inside a WordPress Multisite network. It lets you clone one multisite subsite into another subsite on the same network.
Does NS Cloner work as a WordPress site duplicator?: Yes. NS Cloner duplicates WordPress Multisite subsites, including content, media, settings, menus, widgets, plugin settings, theme settings, and WordPress options.
Can I duplicate a WordPress Multisite subsite?: Yes. This is the core purpose of NS Cloner. You can choose an existing subsite in your multisite network and clone it into a new subsite.
Can I clone a single WordPress site that is not part of a multisite network?: Single-site cloning is available in WP Site Cloner Pro. The free version is for WordPress Multisite only.
What does NS Cloner copy?: NS Cloner copies the content and configuration needed to create an identical multisite subsite, including media uploads, posts, pages, custom post types, taxonomies, comments, menus, widgets, WordPress options, theme settings, plugin settings, and active plugin configuration.
Users and roles are not copied in the free version. User cloning is available in WP Site Cloner Pro.
Does NS Cloner copy theme and plugin files?: No. In a WordPress Multisite network, theme and plugin files are shared across the network, so there is no need to copy those files when cloning a subsite.

What happens if my site is large?: NS Cloner includes background cloning, which helps avoid timeout and memory issues on larger sites. You can close your browser and return later without interrupting the cloning process.

NS Cloner saves me a huge amount of time by copying complete websites in just a few clicks. It’s fast, reliable, and very simple to use. Highly recommended for anyone who regularly duplicates WordPress sites.

really simple and useful

thecreator01 15. juuni 2025

I really like it and I hope new features are released. For example, it would be great to automatically publish a clone when a user signs up and a wordpress multisite site is created. Some processes need to be automated
