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!
So the difference here is you are manually doing a thing for your backups. Using a self hosted server and something like immich will seamlessly do it for you. If you drop your phone in the toilet and it breaks, the photos you took since your last manual backup would be saved.
Immich isnt meant to be a photo gallery viewer primarily, it is meant to be a self hosted photo backup service to replace stuff like icloud or google photos. So yeah, dont recommend it as a gallery viewer, recommend it as a selfhosted image backuo service.
I self host a jellyfin service on my nas, and keep all my movies and shows on that nas. I wouldnt be able to fit all that stuff on my phone.
I worked in an office that was paying out the ass for google drive. Setting up a self hosted nextcloud was a great solution and saved them a bunch of money, and still worked as a hands off “cloud solution”
If you dont want to run a separate machine to self host some services thats fine, you dont need to do it. its not for everyone. But plenty of people have reasonable motives for doing it.
