The Open Siddur Project is a volunteer-driven, non-profit, non-commercial, non-denominational, non-prescriptive, gratis & libré Open Access archive of contemplative praxes, liturgical readings, and Jewish prayer literature (historic and contemporary, familiar and obscure) composed in every era, region, and language Jews have ever prayed. Our goal is to provide a platform for sharing open-source resources, tools, and content for individuals and communities crafting their own prayerbook (siddur). Through this we hope to empower personal autonomy, preserve customs, and foster creativity in religious culture.

The views expressed in contributed works represent the views of their creator(s) and do not necessarily represent the views of the Open Siddur Project's developers, its diverse community of volunteer contributors, or its institutional partners.
