Ready for the cloud

openCRX runs on any J2EE 6 Web Profile compliant application server and supports all major databases. The standard installer comes with Apache TomEE which allows installation with a few clicks on any operating system or cloud service supporting Java. Moreover, with the support of Docker openCRX is ready for the cloud: virtually unlimited scalability, easy move between data centers and clouds, update with zero downtime and more.

Powerful integration capabilities

openCRX is from the ground up service-based and allows easy integration with your existing applications. openCRX features a Java API for Java-based clients and a Swagger-compliant RESTful API. In addition, openCRX comes with a set of adapters supporting WebDAV, CalDAV, CardDAV, IMAP and AirSync for contacts, calendars, documents and e-mail.

Easy to extend and customize

openCRX is extremely flexible and designed to be extended and customized in all aspects and at all levels: starting from simple, XML-based GUI customizing up to modifying the standard business-logic or even extending the API. The strict separation of core and custom extensions allows hassle-free upgrades to newer versions.
