NS Cloner – Site Copier


This is by far the easiest, fastest, and most user-friendly way you will ever create fully configured sites on your multisite networks. The NS Cloner will take any existing site on your WordPress multisite network and clone it into a new site that is completely identical in theme & theme settings, plugins & plugin configurations, content, pictures, videos, and site settings.

Everything is preserved and intelligent replacements are made so that the new site settings reflect your choices for the name and title, and have automatic URL replacements and other background updates to make sure the new site works exactly the same way as if you had taken the time to set it all up manually.

Important: this plugin only works with WordPress Multisite (although the pro version works for single sites as well). You will find its menu in your network administration dashboard (wp-admin/network).

Typical Workflow for using the NS Cloner

  1. Set up 1 or more sites exactly the way you want your clones to start out.
  2. Go to your Network Dashboard > NS Cloner.
  3. Select the site you that want to clone, and enter the desired URL and title of the new site.
  4. Clone away with one click!

Yes, it really is that easy.

Primary Use Cases

  • Developers who host and manage multiple client sites in their own multisite environment – this will allow you to rapidly roll out new baseline sites with all your favorite standard plugins and configurations in place. No more tedious manual repetitive entry!
  • Designers who want to be able to create several versions of sites to test and play with different theme designs in parallel, without wasting time with unnecessary duplication.
  • Teams who want to have a quick way to set up staging sites for collaboration, or effortlessly duplicate content for regional versions of sites, etc.
  • Organizations which provide “member” sites and want to be able to reduce the site spin up time to almost nothing.
  • Affiliates that host numerous sites through multisite and are looking for a way to increase reach and decrease deployment times.

  1. Log in to your WordPress network as a multisite super admin and go to /wp-admin/network
  2. Use the Dashboard > Plugins > Add New tools to install NS Cloner from the WordPress.org repository or install by uploading the zip file
  3. Network Activate the NS Cloner through the ‘Plugins’ menu in WordPress
  4. Access the NS Cloner from its main menu on the Network Dashboard (/wp-admin/network)

Standard Precautions and Notes

  • Unlike some other tools, NS Cloner supports cloning the root site (ID=1). When cloning the root site, the Cloner will automatically exclude all global network WordPress tables (like wp_blogs) as well as global tables for some common network plugins like BuddyPress. It’s impossible, though, for the Cloner to recognize every network-level table for every plugin out there, so it’s possible that some network-level plugin tables could be copied by the Cloner incorrectly, which could result in issues, depending on the plugin. The table manager add-on included in pro is perfect for unique scenarios where you need total table-level cloning control.
  • We always try to help (and you can see the proof of that in the plugin support forum here), but we cannot promise support to users for this free version, especially with issues resulting from non-standard environments.
  • We have used the NS Cloner on production systems for years without issues. That doesn’t mean your scenario won’t find some new condition that could cause you some headaches. Unlikely, but always possible. We recommend getting familiar with it on a test system before you deploy it to a critical network.
  • And for the love – backup your data. This plugin operates at the database level to work its magic. We’ve run it hundreds of times on our own sites and client sites, and tested it thoroughly. It’s safe. But don’t take our word for it.

What exactly does the NS Cloner copy?

The Cloner copies everything you need to have a totally identical twin site: all media uploads, posts, pages, custom post types, taxonomies, comments, menus, WordPress options, theme and plugin settings (including which ones are active).

Users and roles are not copied (that’s a pro feature), and theme/plugin files are not copied because the same files are shared by the whole multisite network, so there’s no need to copy them when cloning inside a network.

Can I clone an individual site that’s not part of a network (non-multisite)?

That is a pro feature – so, yes! With Pro you can easily clone a single WordPress site to another single site. You can even clone a site out of a network to its own individual install or vice versa.

What happens if my site is really large?

You’re in luck! NS Cloner V4 has new background cloning capability, so you should be able to clone a site of almost any size without running into a “white screen of death” from timeouts or memory limits. You can even close your browser and come back to check on it later without interrupting the clone!

There were many plugins that required money to ‘unlock’ this feature, so it’s a great that this did the job and was FREE! Perfect for my Multi-site! 😀

[This review replaces one entitled “Way too flaky”] After great initial experiences I started to have great trouble with this plugin. Having worked things through with the support desk we eventually identified that my worst problems were resolved by CHECKING the option to clear the object cache when cloning. The symptoms I experienced were with settings, content (pages or media), or activated plugins or themes not copying to the new site when doing a standard clone. Should you find this happening, tick that “Flush object cache after cloning” box near the bottom of the settings and see how you go. I think the UI should explain that this option can be used if cloning behaviour is erratic. Another problem persists, which is the UI misbehaving when using (up to date) Firefox – behaviour in Chrome is correct. In FF, the form for defining your clone shows a lot of elements that do not apply to the “standard clone” that is selected when the form loads. They will be validated, so you cannot make a standard clone without first selecting another type of operation and reselecting standard, at which point the correct form elements display. If this can be resolved I can happily award five stars, because this plugin saves an awful lot of pain when it behaves correctly!
