Open Source Cyclos 3.7 offers a feature-rich and adaptable environment for Time Banks, Complementary Currencies and LETS. Cyclos 3.7 is implemented as a Java Servlets Web Application, which makes it robust, secure, and scalable. It is well suited for small groups as well as large scale commercial usage scenarios.

Cyclos 4 is a complete redesign. It uses a Java servlet based backend and a modern javascript based frontend. Cyclos 4 is closed-source and licensed by STRO. It builds on the already rich features of Cyclos 3.7 and adds much more. For example, Cyclos 4 offers full webshop functionality, enabling members to run a currency based webshop. A key improvement over Cyclos 3 is per-user language choice, as Cyclos 3 uses a single language per installation. Although Cyclos 4 is closed-source, many customizations can be made using the built-in scripting and extension facilities. There will be a data migration path if you want to go from 3.x to Cyclos 4.
