For my single user instance, I can be charitable and say that it’s running on hardware that I already had that is running regardless on spare otherwise unused resources with a already registered domain so the only cost is time spent setting it up. Or I could apply all the costs from the server Lemmy, then it would be about $1200 initially plus ~$10/mo per user.
Oh man, I feel like eviltoast.org is on the expensive side of things now. There’s less than 20 mau, but I pay close to $400/mo. Not including object storage or hardware running at home.
Realistically this is hosted on hardware I was already renting for other reasons, so actual cost is zero for lemmy itself. I could probably migrate to a small vm for $20/mo and only lose redundancy.
I managed to bring down ani.social’s monthly costs to only ~14 USD when converted (which includes everything except backups). With 165 monthly users, that comes to around ~0.08 USD with a lot of accomodation.
Lemmy is efficient in resources except in storage (database and images) which grows infinitely. Unless you’re purging older posts and images, it keeps growing (very slowly).
Does the image hosting feature use checksums to reduce the amount of duplicate images?
Right now: 0.3GB per user per month. This number is probably much higher for other instances because I don’t keep copies of federated images anymore and I’ve been compressing images early on.
This doesn’t include bandwidth and backups.
I pay around 80€ per month for the lemmy.ml server, plus a few euros for image hosting and domain. So that’s around 3 cents per active user.
2.39K monthly active users
4th most active instance (https://fedidb.org/software/lemmy/ )
Hosts 10 of the 100 most active communities (https://lemmy.ca/post/26878531 )
The number of users is not really what drives costs honestly. Or at least, it’s not like a linear relationship. I think actually having many popular communities might be a bigger issue.
On that topic, could limiting the posting of pictures and asking people to use external picture hosts help with that?
Yes, storage costs matters. I think it’s honestly crazy that Lemmy caches images as much as it does. It would be great to be able to just disable it completely, but alas you can’t do that without disabling uploads for your own users either (at least I don’t know how).
Yes, but honestly unless you’re very big, federation queries are the bulk of the processing and stuff from your own instance doesn’t matter that much. I mean think about it, do you think the 100 active users on your own instance is what costs or the 10000 users posting all over the fediverse is what matters? Obviously the latter. So again, local user count is not that impactful.
