The freedom to choose between two licenses

There is only one C1 CMS Edition. But you have the freedom to choose between two licenses.

Open Source License

The open source license is absolute free of charge. C1 CMS is distributed under the Mozilla Public License (MPL 1.1). A license approved by the Open Source Initiative (OSI). Read the Mozilla Public License (MPL 1.1).

Commercial C1 CMS License

The Commercial License is with product warranty. Read the Commercial C1 CMS License Agreement. If you want product warranty or have policies preventing you from using Open Source licensed software, our commercial license is for you.

Whatever you choose, you can extend your solution with a number of free and commercial tools, add-ons, support and services. Some made by Orckestra and some made by the community. And you can always convert your choice of license at a later point.
