The Open Siddur Project

The Open Siddur Project is sharing the creative content of Jewish spiritual practice (historic and contemporary, familiar and obscure) in every language Jews speak or have ever spoken. We advocate Jews and Jewish institutions sharing prayers and meditations, exercises and rituals in a way that others can adopt for their own siddurim, adapt to their own circumstance, remix, and redistribute as needed. To facilitate this sharing we advise the owners of copyrighted liturgy, translation, art, and scholarship to share their copyrighted work using free-culture licenses. We work to digitize and transcribe Public Domain liturgy and liturgy-related text and art. To empower Jews to creatively own the means by which they might engage in a spiritual practice, we are developing a web application for users to select, author, edit, and maintain texts online that they can use and share in crafting new Jewish prayerbooks, art, or curricular resources.

While we build this application, we need help collecting the creative content of Jewish spiritual practice (t'fillot, piyyutim, yiḥudim, kavanot, translations, commentary, and instructions) and you can help. Share your copyrighted work via our project or anywhere on the Internet with a free-culture license (CC-BY, CC-BY-SA, or CC0). Help to digitize and transcribe a prayer or prayer, practice, or related resource that is already in the Public Domain, and send it to us. All work shared is rigorously attributed. More information on this free culture and open source software project is available at
