I usually download stuff through Nyaa to get .cbz files of full volumes. Of the few times I have had to get a series myself I have used Houdoku. It's similar to tachiyomi on desktop. I usually rip from Mangadex but have had to manually name folder files to eventually zip into cbz files. This may not be that helpful but just thought it plug in Houdoku to see if it helps with what you need

Edit: Lol I didn't really read your post well. Yeah, personally, I dont know of any automated solutions, sorry.

If you have a Windows/Linux computer you could use FMD/Hakuneko to download manga. The only problem is that these tools do not scrape new releases/new chapters, and so you have to manually go in and download everything.

A workaround would be if you can find torrents for your manga. In which case, with just a little bit of regex, you could let the torrent client (qbittorrent in my case) do the searching and auto-download for you. But I don't really rely on torrents to download manga so can't say. I have been looking for an automated solution too.

Doesn't Readarr (https://wiki.servarr.com/en/readarr) support Manga?

Mylar?

There is no option currently. Readarr has indefinitely postponed adding comics/radarr support.

Mylarr barely does the job and even then it doesn’t do it right due to different naming conventions.

As another said, use qBit with regex on rss or similar with Autbrr if you want faster grabbing if releases

There's no polished arr-like suite for manga at the moment. All we have for now are jank systems that break (FMD2/MangaL/Mango/Lanraragi), take way too much time managing metadata & file naming(random github apps that are cli-based), and Tachiyomi(mobile) + Tachidesk(pc).

I've been in that rabbit hole already and I've wasted too much time (months). I just paid myself and bought an android tablet for exclusively tachiyomi than waste what little free time I have after work.

Hopefully one day we get a fork of tachi without the reader, keeps the plugin support, and improves the metadata & file management (let us set custom series names/numbering when downloading)

I haven't tried Mylar for manga, but it works so well with western comics that it must be possible

I just have FMD sitting in a windows VM, that automatically downloads Into my Komga library which I access via Tachiyomi on phone and Onyx Boox tablet.

Sometimes chapter numbers get fucked up due to amateur releases or errors but overall it works fine.

Komikku (linux) is great on desktop fwiw, though I know that won't be useful for everyone. It's on flathub.

There was Kmanga that did that and sent manga directly to my kindle. It was great but it shut down and no longer maintained.
