This looks really well done. The software is both well-designed (from UX / UI pov) AND it's OSS AND it's just an SSD / NAS underneath it all, I think this kind of thing is a welcome addition to the market.

Ok, and what do I do when these guys go out of business/get bought by Amazon/microsoft/whatever in 3 or 5 years? Like, the game’s up with this cloud stuff, surely. None of it is to be trusted.

Why would anyone want this? It's got a fairly tiny drive size for this day and age, not to mention it appears to just be a generic aliexpress N150 box thats been branded and had their software pre-installed.

IF I already have a NAS/mini pc can I just install this stuff and get all the benefits because I don't need the hardware?

I run an umbrel on an off the shelf mini pc and it’s been great! Very polished and nice experience!

Picked up an Umbrel server to run Bitcoin Knots node last month. Works extremely well, I highly recommend it for similar applications. Nice web based UI.

Cool, but honestly I always end up regretting another device that is not just plain "non user-firendly" Linux. First you buy Synology because it's just quick and easy to set-up, and "I'll figure the rest later". But when time comes to figure the rest out, it's just so unreasonably inconvenient. In theory, it is just Linux, and DSM is just for convenience, and there are special packages intended to use Docker and install stuff and all, but there are so many "user-friendly improvements" on top of that, that I get tired even just thinking about all the hoops I have to jump to do something super-simple and end up choosing some another device for all tasks that theoretically would be a good fit for my NAS to perform. The only good thing is hot-swap and automatic volume rebuild, that is super convenient. But, honestly, are these 2 minutes of convenience worth the rest? I don't know.

"run a Bitcoin node" <closes tab>

Seems to be a hardware + software thing.

Last time I looked at it it had some craptocurrecy stuff, which lost me as a user.
