A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

what is better for single user instance, or maybe something small like under 10 users (no communities)? which is lighter on resources? how much storage should I allocate?

any alternatives to lemmy and kbin that are still somewhat similar?

My Lemmy instance is currently occupying about 350MB of RAM, but you can round that up to 400MB. A lot less than the 4GB for KBin.Technically it's a dual user instance now, since a friend wanted to join it and I said sure.

Damn, this is so much worse than good ol' RSS for just following up stuff (which I imagine is the main argument to be made for a single-usee instance)

[–] [email protected] 15 points 1 year ago (4 children)

The arguments for are varied. I don't have to worry about any admins making decisions on federation, I can federate (or not) however I please. I have my own space that I can do what I want with in a familiar format, and I can make my username Jamie without it being taken.

[–] [email protected] 6 points 1 year ago

Yep, making federation decisions myself is why I want to spin up my own instance at some point, and I have spare computing resources as is already lol

[–] [email protected] 3 points 1 year ago (3 children)

fair points! But that's a high price to pay in terms of computing resources.

I wish federation in the "fediverse" sense was as inexpensive as in the XMPP world (or at least seem to be)

One more anecdote for y'all to pluralize into data: my instance is currently using 915Mi of storage for pictrs and 976Mi for postgres, roughly 650Mi of RAM (including postgres), and negligible CPU

[–] [email protected] 1 points 1 year ago

It's not that bad, I'm hosting my instance in a small corner of a friend's server and not making any impact on it.

[–] [email protected] 1 points 1 year ago* (last edited 1 year ago) (2 children)

High price? It's really not very intensive at all, at low user count. Super light on storage too. I think BeeHaw (one of the biggest instances) said their whole instance was only like 25GB (a week ago)

[–] [email protected] 1 points 1 year ago

I meant, comparatively: you can host thousands of active jabber accounts on a RPi at the same time, and that will cost you pennies in electricity a week. I know this isn't close to an apple-to-apple comparison (different protocols, different capabilities and features, …), but what interests me when people bring-up federated protocols is how much will it actually be used that way in practice (wrt. server dimensioning vs number of users, effort to set-up and administrate, etc), and how effectively we are breaking away from the centralized internet that's so nefarious. And sorry if this is shifting the thread away from where we started at :)

[–] [email protected] 1 points 1 year ago

Yeah, I mentioned on another comment that storage space is the last thing to worry about, 1GB of storage is typically a fraction of a penny.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

My other reason is that it's the only way to know I picked an instance that isn't going to just go away without me and take my account with it. It will be an interesting day when the first major lemmy instance goes down...

[–] [email protected] 1 points 1 year ago

Yeah, if I stick with Lemmy (which seems highly likely) I want to put up my own private instance for similar reasons and maybe even invite friends and family that I can talk into it.

[–] [email protected] 1 points 1 year ago (1 children)

yeah for real I have been thinking the same lol. sadly a feed reader is just a reader. Would not be able to comment or post, which is the main reason I will go with a self hosted instance.

[–] [email protected] 5 points 1 year ago

As a middle ground you could follow a Lemmy community‘s RSS feed then jump in via the link for anything you wanted to see the conversation for :)

[–] [email protected] 1 points 1 year ago

Keep in mind as php-fpm (used by Kbin) launches multiple child processes instead of a single rust process like Lemmy. The number of child processes can be tuned down to reduce RAM usage if necessary.

[–] [email protected] 0 points 1 year ago (2 children)

Thanks for the info! what about storage capacity usage?

[–] [email protected] 8 points 1 year ago (2 children)

After almost 24 hours, coming up on 662MB of images, and 371MB for the postegres database. Though, I could see the numbers fluctuating depending on how much stuff you're subscribed to. I'm currently subscribed to 31 communities, most of them fairly large.

[–] LargeHardonCollider 2 points 1 year ago (1 children)

I’m still kinda new to lemmy, but it sounds like every post on all your communities get sent to your instance? And maybe every comment?

That’s probably fine for now, but when happens when one of the communities you follow gets a ton of users? I imagine you’d end up having to scale your self-hosted server even though it’s just you consuming the content?

That doesn’t seem sustainable. Not knocking your idea to self-host, more concerned with the scalability of lemmy

[–] [email protected] 6 points 1 year ago

That's correct. I'm replying to you on jamie.moe right now, but in reality, what I'm seeing is a copy of what lemmy.world has. When someone makes a post, leaves a comment, or whatever, all of the instances that are federated and have one subscriber in the relevant community get updated with the change.

When I read this thread, I'm actually reading a copy of the thread stored on my own instance, and my instance just tells lemmy.world when I leave a comment and it will update everyone else. While it isn't very storage efficient, it does even out the load since users on one instance only require a single update from the main instance for all of those users to interact with that content, rather than instances asking for copies of things every time a user on one instance needs it. It spreads out the load nicely and lets even underpowered hardware serve wider communities than it could otherwise.

The downside is you have to have the storage space to keep content for your user(s). Though, getting a lot of storage space isn't expensive at all, so I would say it's a minor concern. Lemmy uses little in terms of RAM and compute, those two factors are the biggest things that can up your cost really fast. A gigabyte of storage on a server can typically be gotten for a fraction of a penny.

BeeHaw.org admin said like a week ago they were only up to 25GB.
