Mura is available with two license options: open source and commercial. Our primary focus is on making Mura available as an open source (and free) application, but we recognize that some organizations prefer (or even require) commercial licensing, so we offer a commercial license as well.
Our open source license is the GPLv2, with a special exception that allows developers to release Mura plugins, themes and site bundles under the license of their choice - open source or commercial. We created this exception to foster the ability of developers to benefit from their work by providing them with the option to charge for their work in a clear and unambiguous manner.
The text of the license is as follows:
<!--- This file is part of Mura. Mura is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, Version 2 of the License.
Mura is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with Mura. If not, see <http://www.gnu.org/licenses/>.
Linking Mura statically or dynamically with other modules constitutes the preparation of a derivative work based on Mura. Thus, the terms and conditions of the GNU General Public License version 2 ("GPL") cover the entire combined work. However, as a special exception, the copyright holders of Mura grant you permission to combine Mura with programs or libraries that are released under the GNU Lesser General Public License version 2.1.
In addition, as a special exception, the copyright holders of Mura grant you permission to combine Mura with independent software modules (plugins, themes and bundles), and to distribute these plugins, themes and bundles without Mura under the license of your choice, provided that you follow these specific guidelines:
Your custom code
• Must not alter any default objects in the Mura database and
• May not alter the default display of the Mura logo within Mura and
• Must not alter any files in the following directories.
You may copy and distribute Mura with a plug-in, theme or bundle that meets the above guidelines as a combined work under the terms of GPL for Mura, provided that you include the source code of that other code when and as the GNU GPL requires distribution of source code.
For clarity, if you create a modified version of Mura, you are not obligated to grant this special exception for your modified version; it is your choice whether to do so, or to make such modified version available under the GNU General Public License version 2 without this exception. You may, if you choose, apply this exception to your own modified versions of Mura. --->
Our Mura commercial license is an appropriate choice for organizations that are not comfortable with the use of open-source licensing, but wish to use Mura. The commercially-licensed version of Mura contains exactly the same functionality and code as the open-source versions, but includes indemnity from potential IP violations; a key factor for many organizations.
Mura's commercial licensing costs are:
- Base install (1 site) - $9,500
- Per additional install for clustering - $9,500
- Staging server - $7,500
- Per additional site - $2,500
These costs are for the initial purchase and include 1 year's licensing. Licensing for additional years costs 20 percent (annually) of the initial purchase price. Support is not included in our commercial license and must be purchased separately.
