The XSF is a U.S. 501(c)(3) organization. It sometimes acts as a fiscal host for open source projects related to XMPP.

The XSF may choose to accept organizations at the discretion of the board, treasurer, or anyone else to whom the board has delegated this authority. Projects must be open source with source code, documentation, resources, and other non-code assets released using an OSI approved license (https://opensource.org/licenses/alphabetical) or a Creative Commons license (https://creativecommons.org/licenses/). Trademarks will continue to be held by the project and the XSF will not take ownership of any project assets. The XSF will not charge a fee for this service.
