Xuni follows the standard ComponentOne licensing and subscription model in that licenses are per-developer. A Xuni subscription includes all updates, bug fixes and official releases for one year. For example, if you purchase 2015 v1 you are entitled to use versions 2015 v2, 2015 v3, 2016 v1 and every version in between. A subscription entitles you to unlimited, royalty-free app redistribution using any valid version of Xuni.

Your subscription also includes email and forum support. You may also buy platinum support to get your queries handled within 24 hours or on the phone by ComponentOne's support team in Pittsburgh. Whether you choose to go for a subscription or not, MESCIUS (formerly GrapeCity) and ComponentOne provide your developers, access to the community forums that are regularly monitored by the support team.
