Keygen is now Fair Source
a day ago
- Keygen has relicensed from ELv2 to the Fair Core License (FCL), a Fair Source license that sits between Open Source and source-available.
- The FCL addresses ELv2's problem where users risk losing access to commercial features if the licensor goes out of business.
- Under FCL, commercial features are protected by a license key, and after two years, the code converts to an open source license (Apache 2.0).
- This approach provides longevity and continuity for users, while still protecting Keygen's business model without being predatory.
- The FCL is based on the Functional Source License (FSL) but adds limitations to protect license-key-protected features, ideal for 'open core' projects.
