1. Service and Authorization
For users to integrate Slickflow into their own projects, Slickflow supports both the Community Edition Open Source Agreement (LGPL) and the Enterprise Client Edition Commercial License Agreement：
1.1 License
1) The use of the community version needs to follow the LGPL agreement；
2) For enterprise users, in order to avoid the restrictions of the open source agreement (LGPL) of open source projects, they can purchase commercial licenses for the commercial operation of their own businesses.
3) Commercial authorization is only applicable to the development and system integration of the customer's own system, and cannot be used to repackage and sell the workflow engine; that is, the Slickflow workflow engine has independent copyright and brand.
4) After commercial authorization, engine components (compiled dynamic library files) can be distributed with customers’ own products for commercial use. Customers can modify the engine source code, but cannot disclose the engine source code.
1.2 Service Support
Technical consultation or the development of new functions can be carried out as a paid service. The development team will provide some timely consultation services or the realization of new requirements; a certain technical service fee shall be charged according to specific functional requirements.
