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?
They had DMCA requests for 800+ titles so it’s functionally crippled at the moment and it seems like they’re pivoting to becoming a self-published webtoon platform instead. Check here: https://mangadex.org/compliance/copyright-faq
