I used Jackett until I had to transfer some split up programs to the same machine. Some indexers needed Flaresolverr but it was broken, because my version of Jackett was a service install instead of docker. Anyway it made sense to switch to Prowlarr because I already use Sonarr and Radarr
Jackett I think is a better solution. There is a crazy amount of sources to search/select from and setting up the API key is just editing a file.
