The organization was founded in late February 1998 by Bruce Perens and Eric S. Raymond, part of a group inspired by the Netscape Communications Corporation publishing the source code for its flagship Netscape Communicator product. Later, in August 1998, the organization added a board of directors.
Raymond was president from its founding until February 2005, followed briefly by Russ Nelson and then Michael Tiemann. In May 2012, the new board elected Simon Phipps as president and in May 2015 Allison Randal was elected as president when Phipps stepped down in preparation for the 2016 end of his board term. Phipps became President again in September 2017. Molly de Blanc was elected President in May, 2019, followed by Josh Simmons in May, 2020.
The organization appointed Stefano Maffulli as its executive director in September 2021, at the end of a process set by the board of directors to transform the organization. Josh Simmons is chair of the board.
