I searched for ages for a replacement of something like torrentz, and the rarbg drop made me start the search again. I ended up trying the included search in qbittorrent, and I’m very happy with the results, it scans many public trackers, and I have always found what I wanted.
To be clear, qbittorrent is a desktop app for linux/windows/mac, that has a panel where you can search for torrents:
For me the loss of RARBG was more about the site’s quality and interface. Torrents aren’t hard to find but consistent quality and selection are (outside of a lot of private trackers). I liked that they displayed popular movies at the top so that I can keep up with what’s currently in vogue for my users (since i dont really see any ads anymore) without going through the extra effort of manually googling what new movies are coming out every few weeks.
