Hands down, Sefaria is definitely the largest and easiest to navigate torah text site. They have all of Tanach, Gemara, Mishnah, and major halacha seforim, as well as Midrash, Kabbalah and many more seforim. Everything is very clearly categorized and can easily be searched by page, perek or a specific word. A very large portion of the texts have been translated to English and you can view it side-by-side with the original Hebrew text. You can also click on any sentence, and it will pull up any relevant meforshim on that piece.
2. WikiText – ויקיטקסט
Built on the Wiki platform, their layout is quite familiar and simple to use, and they have a similar selection of seforim as Sefaria.
What’s unique about Mercava is its Shakla v’Tarya feature, which you can click on a word or phrase in the Gemara and it will translate that part as well as inform you if the sentence is a ‘statement’, ‘question’, ‘defense’, or ‘answer’ to help you understand the gemara. They also have the Tanach and Gemara in it’s familiar layout with the meforshim around the text. For teachers or chavrusas you can learn together with another person on the same text with where you can follow along on the page, or upload a shiur and sync your words with the text on the page.
