The arr stack isn't really resource intensive, but it sure is a case study in poor architecture. You need 10 services that each do a tiny job and often rather poorly. Setting it up by hand would be maddening but it was trivial with Claude.

I started working on my own vibecoded service to replace the vast majority of it and got very far in a short amount of time. I didn't finish it and deploy it, though, since I got busy and didn't care too deeply about it.
