I have bought my first proper home server and am setting up a full stack of media services on truenas scale after years of doing everything manually. In that regard I have set up jellyfin, sabnzbd and radarr, and the next step is to add jellyserr it seems. But then I stumble across prowlarr and cannot figure out if it is a contender to or a supplement to jellyserr. Can somebody tell me what the difference is, if I should use both if they are complementing each other or which you are using if they are competing?
If you are only using usenet then prowlarr will do nothing. Prowlarr aggregates torrent indexers and searches them for your request
That is not correct. Prowlarr also searches Newznab-compatible providers (i.e. most nzb-indexers).
