Sefaria

Sefaria is an online open source, free content, digital library of Jewish scriptural, theological, philosophical, legal, mystical, historical, and ethical texts. It was founded in 2011 by former Google project manager Brett Lockspeiser and journalist-author Joshua Foer. Promoted as a "living library of Jewish texts", Sefaria relies partially upon volunteers to add texts and translations. The site provides cross-references and interconnections between various texts. Hebrew, Aramaic, and Judeo-Arabic texts are provided under a free license in the original and in translation if available. The website also provides a tool for creating source sheets. Sefaria is maintained by an eponymous non-profit organization, which employs 18 engineers. According to its chief data officer, Lev Israel, in 2019, the service received 250,000 unique visitors monthly. The average monthly number of users increased to 775,000 in 2024, according to the year's impact report, with users from 234 countries.
