Am i the only one who finds the *arrs to be.. not great? Be it UI, UX, deployability (C# .NET required magic reverse engineered stuff like Mono to work on Linux/*BSD where most people would run them on, and IIRC none of them are on .NET Core yet), error handling. I once spent an afternoon trying to get Jackett go work on FreeNAS due to some library mismatches due to the magic sauce required to run Windows software on FreeBSD. It baffles me 1) that software stack was chosen in the first place 2) it was reused for all other *arrs 3) it still remains in use today 4) there are no alternative tools using a saner tech stack. Not to mention the fact that I don't see the point in having different *arrs for music, films, series, when the functionality is 90% the same and it could just be different toggable tabs... I was so pissed i hesitated trying to rewrite all of it in Django or something.
They run great on arm, too! I got a raspi 4 running everything smooth as butter. The most problematic aspect is interfacing with the usb drives; I eventually had to move them to a powered hub to get the required current.
