Excluding Nyaa or private trackers, as many ongoing and more obscure titles aren’t available to torrent. I’ve been using Comick and Weeb Central, but I don’t really know how up to date they are on new scanlations as I think they’re mostly aggregating from other sources?
I use this site to keep up to date with all of my weeb endeavours.
The link I gave you is specifically for manga and currently ComicK is their top pick.
Great site! Thanks
