No. CUBA Studio is complementary to a Java IDE. It brings huge time savings by automating CUBA-specific part of the development process, but we recommend to use a Java IDE to work on the source code. We even provide a plugin for IntelliJ IDEA / Eclipse to improve your IDE experience.

The standard web client for CUBA applications is the generic UI based on Vaadin. It is seamlessly integrated with the server side, very rich functionally and facilitates very fast development. So, it is the recommended option in most scenarios.

The alternative Polymer client interacts with CUBA middleware over REST API. It is intended to support mobile-first front end with complex UI requirements. In example, it can be used to create a customer facing portal of your enterprise system, keeping admin and back office UI implemented with the standard web client.

We recommend to take the following steps:

CUBA Studio 7.0 and up has acquired a different licensing policy:

  • There is no limit for a number of entities;
  • Premium add-ons for CUBA Platform v7+ are now open source. Addons for previous versions are still distributed under the old license;
  • Visual development tools such as screen and data model designers are now included into commercial subscription, while functionality related to working with code is free. Commercial features of Studio 7 are available as a free trial until June 1, 2019. The trial is issued automatically after the first launch.

CUBA Platform is licensed under the open-source, non-restrictive Apache 2.0 license.

CUBA Studio is available in free and commercial versions. The free version is fully functional, but limits the size of your application data model to 10 entities and does not support Premium Add-ons. You can always remove this limitation by purchasing the commercial license.

Commercial license is per developer. The license is concurrent, so you do not need to provide the names of developers, who will be using Studio. It means that any developer can use a license, but not two developers at the same time.

The full license text is available here.

Premium Add-ons are included in the commercial subscription of the CUBA Studio and are licensed on the same license terms. Commercial CUBA Studio users get access to source code repository, and Studio can automatically add the required add-ons to your application.

The Add-ons license does not limit the way you use or distribute your application. After the subscription expires you may still use the versions of Add-ons you have downloaded previously.

No. As CUBA Platform is distributed under Apache 2.0 license, it does not imply any substantial limitations on applications. CUBA Studio is only used at development time and is not required to run your application. Premium Add-ons require a valid license only at development stage.

After the subscription has expired Studio will be working in ‘free’ mode. This means that it will not open projects, using Premium Add-ons, or with data model exceeding 10 entities.

Yes. After the subscription expires you will not have access to Add-ons repository, but you can use the versions you previously downloaded.

The full list of libraries, used by the latest CUBA Platform and Add-ons releases, is provided here. The list of libraries, used in CUBA Studio, is available here.

All libraries we are using are distributed under open source, non restrictive licenses - like MIT, Apache 2.0, EPL, LGPL. We do not use libraries with ‘copyleft’ licenses like GPL.

Note: Premium Add-ons provide integration with some products, which may have commercial license - like Google Maps or amCharts. It is your responsibility to make sure you use them properly.

All forks of third party libraries, used in CUBA Platform, Add-ons and Studio are distributed under the same license terms as the corresponding library.
