Same. I made the mistake of adding the downloader to it at the start but brute forced my way through. Single Rust binary for all of the *arrs + sabnzbd is nice though. Unfortunately it is not something I am comfortable making public due to the all-in-oneness of it.

Almost all of the time went to to the downloader (usenet is more complicated than I thought). If I had just focused on the basics (sonarr, radarr, seerr) I could probably could have knocked it out in a day or so.

It is important to point out that “a day or so” - or even the ability to spin up your own version - is only possible because these projects already exist.

Without a tested and validated reference implementation that already accounts for the numerous edge conditions and quirks of media releases, APIs, etc., your vibecoded version would have taken much longer to iterate on.
