Chabad.org
The most comprehensive, accessible, Orthodox-perspective Jewish website on the internet.
Summary. Chabad.org is the flagship online presence of the Chabad-Lubavitch movement and is, in practice, the most comprehensive single-stop Jewish learning website. Articles on every holiday, every parshah, every life-cycle event, every halacha. Daily Tanya study, daily Rambam, daily Chumash, with audio classes. A locator for Chabad houses worldwide. The orientation is Chabad-Hasidic, but the practical guidance is straight Halacha. A New Jew should bookmark it.
What It Has
Parshah articles — multiple commentaries on each weekly Torah portion, from the Lubavitcher Rebbe and others.
Holiday guides — practical instructions for every Yom Tov and Chag.
Halacha — short clear articles on practical questions (kashering a kitchen, lighting Shabbat candles, building a sukkah).
Tanya — daily study with audio, English translation, and commentary.
Daily Rambam — the standard Rambam Yomi study cycle.
Chabad House locator — find your local Chabad anywhere in the world.
Stories — Hasidic tales and contemporary outreach stories.
Children's content — for the New Jew with young kids.
The Editorial Slant
Chabad.org reflects Chabad-Lubavitch hashkafa: emphasis on the divine spark in every Jew, on outreach and welcoming, on the centrality of the Rebbe (Rabbi Menachem Mendel Schneerson, 1902–1994) as the great teacher of our generation, and on a particular Hasidic understanding of the messianic moment. The Halacha presented is straight Chabad practice (which is essentially mainstream Orthodox with some Chabad-specific customs). A New Jew should be aware of the slant but will find the practical guidance reliable.
How to Use It
Two practical uses dominate: (1) searching for a particular halachic or holiday question — Chabad's short articles are excellent for "how do I prepare for Pesach this year"; (2) finding a Chabad house wherever you travel. Chabad's universal accessibility — every Chabad house welcomes any Jew, asks nothing, and provides Shabbat dinner, a place to stay, or any other support — is one of the great gifts of contemporary Jewish life.
Where Denominations Diverge
Chabad-Hasidic; practical content is mainstream Orthodox. Some Modern Orthodox readers find the messianist undercurrents distracting; some Reform readers find the assumption of full halachic observance challenging. Both groups still use the site for practical reference.
