Planka, a self-hosted Kanban board service for organizing teamwork and tracking tasks, has switched to a proprietary license. The project initially used the Expat/MIT license, switched to the AGPLv2023 license in 3, and now uses a proprietary Fair Use License, based on the Sustainable Use License. The license change was made in the second Planka 2.0 release candidate, so the 2.0 branch will be proprietary.
The author of the project considers the discussion about changing the license closed. The developers assure that "for the majority of users of the community version of the product nothing will change", keeping silent about the fact that the new license has not been approved by the OSI organization and the FOSS Foundation, since it does not meet the definition of Open Source and the criteria of Free Software.
The Fair Use License allows the use and modification of the source code only for personal use, training, or to support internal company processes. Using the code base to create paid products or services offered to third parties (for example, providing other legal entities with access to a deployed instance of Planka) is prohibited without purchasing a separate commercial license.
Meanwhile, for more than two years (since the Planka project switched to the AGLPv3 license), the 4gaBoards fork has been actively developed, continuing to use the Expat/MIT license. The fork implements a number of new features that are missing in Planka, including: extended interface customization options (collapsing columns, displaying as a list); tools for integration with external services (including authorization methods and synchronization); a sidebar for navigation between projects and boards; board templates.
