What is Fair Source Software?
++ Fair Source Software (FSS): +
+-
+
- is publicly available to read; +
- + allows use, modification, and redistribution with minimal restrictions + to protect the producer’s business model; and + +
- undergoes delayed Open Source publication (DOSP). +
+ The intention is for the first point to be a bright line, and for the + second to invite exploration. We expect Fair Source licenses to emerge and evolve and shake out into a few clear winners over time, + as companies apply Fair Source within their own particular + business context. +
+ ++ The third point is also intended as a bright line, and a key + differentiator of Fair Source from Open Core and other approaches. Delayed Open Source publication (DOSP) is a concept established by the Open Source Initiative (OSI). It is in keeping with OSI's public-benefit mandate + to "persuade organizations and software authors to distribute source software + freely they otherwise would not distribute." DOSP ensures that if a Fair + Source company goes out of business, or takes their software in an undesired + direction, the community or another company can pick up and move forward. + Will this be meaningful in practice? Again, time will tell. +
+ +Why Fair Source?
+ ++ The purpose of Fair Source is to legitimize the practice of companies + sharing their core software products to a business-justifiable extent, + without confusing this sharing with Free and Open Source Software. + Companies that adopt Fair Source value user freedom alongside their + own sustainability, and quite often maintain and contribute both + financially and in other ways to genuine community-governed FOSS + projects alongside their commercial Fair Source products. +
+ +Who is behind Fair Source?
+ ++ Fair Source began as an initiative of Sentry + in 2024, in response to a 2023 call-to-action + from Chef co-founder Adam Jacob. Fair Source is managed on GitHub. Governance + and process documentation is in the README. +
