Umbraco UI Builder is a commercial product. You can run an Umbraco UI Builder unrestricted locally without the need a license. Running Umbraco UI Builder on a public domain will display a warning banner in the backoffice and will limit usage to a single editable collection. To remove these restrictions, you'll need to have a valid license.

How does it work?

Licenses are sold per backoffice domain and will also work on all subdomains. If you have alternative staging/qa environment domains, additional domains can be added to the license on request.
The licenses are not bound to a specific product version. They will work for all versions of the related product.
Let's say that you have a license configured for your domain,, and you've requested two development domains, and
The license will cover the following domains:
  • localhost
  • *.local
  • *
You can have only 1 license per Umbraco installation.

What does a license cover?

There are a few differences as to what the licenses cover:
  • A single license covers the installation of Umbraco UI Builder in 1 production backoffice domain, as well as in any requested development domains.
  • The production domain includes all subdomains (e.g. *
  • The development domains work with or without the www subdomain.
  • The license allows for an unlimited number of editable collections.
  • The license also includes localhost and *.local as a valid domain.
If you have multiple backoffice domains pointing at the same installation, you can purchase and add additional domains to your license.
This is an add-on domain for existing licenses. Refunds will not be given for this product.
