List of free and open-source software organizations

From Wikipedia, the free encyclopedia

The following are notable organizations devoted to the advocacy, legal aid, financial aid, technical aid, governance, etc. of free and open-source software (FOSS) as a whole, or of one or more specific FOSS projects. For projects that have their own foundation or are part of an umbrella organization, the primary goal is often to provide a mechanism for funding development of the software.

For the most part, these organizations are structured as nonprofit/charity organizations.

This list does not include companies that aim to make money from free and open-source software.
