Why It Matters

Open source software runs the world. Not only is most of the internet based on open source software, but thousands of programs, non-profit organizations, and companies depend on openly developed software libraries.

Currently, lots of open source libraries have only a single person who is responsible for its maintenance. However, reasons for not being able to put time into security fixes and the further development of a project are manifold. They reach from leaving the company or losing interest, to changes in your personal life, up to sad circumstances like illness, burnout or death.

If maintainers are not able to look after their projects anymore and they did not give anyone else access to their repository and the package registry, trouble is sure to follow. It will get harder and harder to keep the project well-maintained, even if the community is involved in taking it over.

Adoptoposs claims that open source software can be better maintained and maintainers will be healthier when following one important rule:

“Each and every open source software project of considerable popularity should have a team of co-maintainers.”

When a project gains popularity, original creators and maintainers will need help. Adoptoposs offers them a platform to find co-maintainers or put their projects up for adoption. It allows to make the initial contact between maintainers and future co-maintainers.
