Yes, it but doesn’t integrate into qBittorrent like Jackett does. Jackett is more for manual searching, prowlarr integrates better with other *arr services.
For me, prowlarr works much better together with qBittorrent, sonarr and radarr. + Add Flood to the list for easier mobile friendly UI for qBittorrent.
I’m using the official qbittorrent remote app. I like the UI better. And use Nzb360 to manage my *arr apps remotely
