This is hard, because on one hand I do love self-hosting (I self-host a number of the services they list in their "App Store") but I don't quite get the target market for this (probably because I'm not in it).

The lack of RAID or similar means that you've traded the cloud for 1 component losing all your data. Coupled with the lack of any (obvious) backup solution is concerning. Do you really want to backup your files/images to a single point of failure? If this is supposed to be turn-key then I think there are opportunities to sell cloud backup as an add-on but as-is you are handing people a ticking time bomb.

I'm not a fan of the Crypto angle highlighted in the store, it's a red flag.

I'm interested in what the app compatibility story is here. Like how much post-install configuration are they handling?

> Sonarr on umbrelOS will automatically connect to download clients installed from the Umbrel App Store. Choose from Transmission, qBittorerent, and SABnzbd. Simply install your preferred client(s).

Does that mean they have post-install hooks (on both Sonarr and the download client's end) to configure those? Or is that just speak for "Yeah, you can easily configure XYZ download client that you also installed".

All-in-all it seems overpriced and limited for what it's offering and that's all assuming they stick around and don't peter out. Maybe this is a good first step for someone interested in this but I feel like the type of person interested in this either already can figure out how to set it up themselves (Synology, UnRaid, Docker, etc) or will need a lot of handholding when things break/don't work as expected.

It's entirely possible that there are a lot of people that this would be good for, I just don't know who it would be.

Lastly, no mention of anything like SSO or Remote Access (both things that could be a good value-add IMHO alongside cloud backup). It's overly nerdy in some ways and underly nerdy in others which is why I can't figure out the target audience.
