Selfhosting is useful when you either need a lot of storage or a lot of processing power. For example, Kiwix is useful to selfhost on a server because a lot of its content can take up terabytes of storage, which a phone may not have. LLMs are also useful to selfhost because they require a degree of processing power that, again, a phone may not have.
In both cases, there is also a need for perpetual access. If you simply hosted an LLM on your home computer, it wouldn’t be very useful to access from your phone since your computer won’t be running all the time. So, a separate always-on server is needed.
However, there are some selfhosted software that I don’t see a use for. For example, Immich. Immich requires to be run on a server to function, but a lot of (or even all) of its functions are things that could reasonably done entirely on-device. Aves combined with some automatic backup solution such as Nextcloud gets (from what I can tell) most of the functionality Immich offers. Obviously, some features like AI image tagging are missing, but you get the point. AI image tagging is also something that could be run on-device as well, since it’s mostly lightweight (iPhones are capable of it). Having a setup like that also comes with the benefit of automatic backups being completely optional, rather than required.
There’s no reasonable need for extra storage or extra processing power needed for that use case, from what I can tell. (Disclaimer: I haven’t actually used Immich before, so this is speculation. I apologize if I’m missing something obvious) There’s a lot of other selfhosted tools like spotDL which have a selfhosted web UI, but no GUI that can be installed outside of a web browser.
I guess my question is why there are so many selfhosted tools that unnecessarily require being run on a separate device. I do understand the legitimate use cases some of them have, but others seem better off on-device airgapped. This especially became an issue trying to find a notes app for Android that requires no account and runs fully locally, or an RSS reader that loads from the device itself. I found Joplin and Feeder or Read You as the software for each of those. I don’t like “server-based” selfhosting for things that could be done from the device itself.
I’m sorry if this turned into a rant. If someone could help me understand, I would appreciate that very much.
Cheers!
That’s a good point, and I agree. I still wish Immich could function as an on-device photo app, with selfhosted backups being optional.
On device isn’t always ideal. I don’t use immich because i don’t have a large photo library. But I do use komga. Nextcloud can sort and manage epub/pdf like komga but as poVoq said, the specialized solution is superior
This point is where on device app is not the ideal situation, for me at least. These apps exist. Tachiyomi and the resultant forks can import a local library. And frankly even a somewhat massive local library can fit on a cheap SD card
The point of the server is portability. With this I have portability across my devices. My library, reading status, metadata, etc is available on all devices. I can read a book on my ereader, close it, the status is synced. I can pick up from my laptop and the same thing occurs. I can pick up from my phone, download the book to my device, and keep reading while I’m away from home. If I wanted to I could open remote access to my server and avoid the need for downloading the books but that’s a whole thing
I don’t think it would make sense to run a server solely for this but it’s a service that doesn’t take much in terms of resources and I read a lot.
