The Open Siddur Project is a volunteer-driven collaboration between folk passionate about Jewish spiritual practice. Some are interested in the Siddur as a technology for preserving and disseminating an evolving history of Jewish ritual, practice, and sacred poetry. Others are energized by the design challenge of crafting Siddurim that function effectively for nurturing spiritual, emotional and creative intelligence. All of us see the potential that creative engagement holds for empowering students and teachers to take ownership of those ingredients comprising their shared cultural inheritance.

The Open Siddur is a non-prescriptive, non-denominational project whose only intent is to help revitalize Judaism by ensuring its collective spiritual resources — the creative content intended for communal use — remain free for creative reuse. The Open Siddur Project invites participation without prejudice towards ethnic heritage, skin color, nationality, belief or non-belief, sex, gender, sexuality or any other consideration. All we ask for is an intellectually honest commitment to the principles and sensibilities preserved in our mission statement.
