MoSync AB distributes the MoSync® SDK under the standard GNU General Public License (GPL) version 2. That means it is completely free for private use. You can even sell your applications commercially, as long as you make your source code available to others.
Individuals, businesses, and organizations who distribute MoSync-based applications but who do not wish to publish their source code, must purchase an annual Basic Pro, Gold Pro, or Platinum subscription. Basic Pro and Gold Pro subscriptions are sold on a per seat basis.
You can also order your subscription via mail to sales@mosync.com

MoSync Community Subscription
If you develop Free Open Source Software (FOSS) applications that you distribute under the terms of the GPL license, the open-source community version of the MoSync SDK is all you need. The GPL for the MoSync SDK (which is included in the MoSync installation package) permits you to copy, distribute, and modify the MoSync SDK or its parts in any way you like, provided that you conspicuously and appropriately publish on each copy of the MoSync SDK or its parts an appropriate copyright notice and disclaimer of warranty, keep intact all the notices that refer to the GPL and to the absence of any warranty; and give any other recipients of the MoSync SDK a copy of the GPL along with the program.
Visit the Free Software Foundation’s website to read more about GPL. The Free Software Foundation provides a detailed FAQ on the GPL. The Software Freedom Law Center has also created A Practical Guide to GPL Compliance with its explanation of the GPL's requirements.
Commercial Subscriptions
Individuals, businesses, and organizations who combine and distribute their commercial software with the MoSync SDK or its parts but who do not wish to publish the source code of that software under a General Public License must obtain a commercial subscription from MoSync AB. Purchasing a commercial subscription frees you from the need to conform to MoSync's GPL license (the standard GNU General Public License version 2). The commercial subscription includes the assurances that distributors typically find in standard commercial agreements.
Our Basic Pro and Gold Pro subscriptions are available for a low annual fee (see table above). These subscriptions are sold on a per seat basis: one commercial subscription is required for each developer who uses the MoSync SDK.
We offer a Platinum subscription to customers who wish us to provide extended services, such as:
- Prioritized feature requests
- Non-recurring engineering (NRE)
- On-site support
- Training and education
- Device testing
- 24/7 email and phone support
- Floating subscriptions (unnamed developer seats)
For more information about GPL licensing and our commercial subscriptions, please contact sales@mosync.com.
