I'm learning Eruvin, and am interested in finding insights and understanding to tosfos. So while you're tosfos linear translation is helpful, it doesn't explain the understanding behind.
Do you have any resource like that or can you point me to something like that? Or shiurim?
Thanks, Rafi H.

Shalom, Rafi, it's always nice to hear from you!
Eruvin is certainly not easy, we wish you much Siyata d'Shmaya going through it and thoroughly understanding the Maseches, with Tosfos!
As for in-depth resources for Tosfos -
1. First and foremost, be aware that you can always submit questions to our Kollel, as often as you'd like. We don't yet have AI in place to give an immediate answer based on our existing material, but the Avreichim usually get back to you within a day.
2. Online, I am not aware of such resources. But in print, although in English the Artscroll series is still in Moed, some wonderful works on Tosfos are available in Hebrew for all of Shas - notably the Oz v'Hadar Shas 'Mesivta' with Biurei ha'Tosfos.
3. Mechon ha'Meor also has a nice Tosfos ha'Mevu'ar, which are printed stand-alone and certainly much cheaper. See here, for example.
4. (Mechon Or l'Yesharim also has volumes of 'Biurei Tosfos', but they've only reached the end of Nezikin, as far as I can see. Same goes for Rav Oksenberg's Sha'rei Tosfos, and Rav Nachman Kahane's Mei Menuchos, or Oz v'Hadar's Tosfei Tosfos.)
Wishing you Hatzlachah again,
