Sefaria: A living library of Jewish texts.

"Sefaria" is a free collection of Jewish texts, that goes from the Hebrew Bible to the Mishnah, Talmud, Zohar and different rabbinic commentaries in Hebrew and English. People can contribute with articles or translating.

From their description:
"We are building a free living library of Jewish texts and their interconnections, in Hebrew and in translation. Our scope is Torah in the broadest sense, from Tanakh to Talmud to Zohar to modern texts and all the volumes of commentary in between. Sefaria is created, edited, and annotated by an open community."

You can even download their entire database for free. It's a great resource!
