Good question!

Mine's a small instance and runs on my existing infrastructure, so my only real cost (aside from a crazy amount of unpaid time and stress) is the domain name which is about $20/year.

If I moved it to dedicated infrastructure, I've estimated it would cost me about $65/mo for just the backend, UI, and database services (to maintain the same level of performance, anyway. Could probably host it for less and take a performance hit). Object storage for pict-rs would probably be around $10/mo since I force it to use webp and have a 512 KB limit for user uploads.

Those numbers may be a little high, but they're based on my existing VPS provider which has amazing SLAs and uptime.

Feddit.uk makes our finances public, about £35 a month. So about £0.11 per active user.

Also, I run sappho.social out of a £5 a month VPS.

Here’s the stats for mastodon.world and Lemmy.world

(And a few other fediverse sites)

https://blog.mastodon.world/blog-post-for-august-2024-and-july

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.

ive purposefully stood up my instance in a production, scalable environment.

i make my costs public on the https://moist.catsweat.com/faq page.

currently running ~1.60/day = 50$/month...

so far about $0.50/per user/month or $1.25/active user/month which should move downward until i hit resource limits and have to scale infrastructure.

Masto admin here. Small instance. 20ish users. costs me about 1€ per user.

Most of the costs comes from media cache storage, so it would scale nicely if I had more users, but I want to keep it small

6.84€ per month. And that's 6.84€ per user. But I also run a dozen of other services on that VPS.

About 62 USD per month. I post monthly finance updates. All the costs are covered by user donations so far :)

It might be possible to do it cheaper, but I feel I got a good deal for some very high end hardware so this setup should be scalable going forward for a long time.

Mastodon is used by me alone and costs ¥1590/month.
Misskey is free with OCI for less than 5 people.
PieFed is ¥491/month.

Lemmy is the biggest server in Japan, but I host it at home because it has about 5 MAUs.
(Unfortunately, it is not popular in Japan.)

Media is R2, but it is still within the limits of no billing.

Interesting pattern emerging, the IT time of the admins is pretty damn priceless, (thank you admins!) but when an instance gets up to scale a lot of them can end up with a hard cost of 10 cents per user per month.

The last stat I remember from Facebook was revenue per user per year was around 4 dollars. At 31b revenue and 2.7b monthly users, Youtubes average profit per user is about $10 per user per year. 100 million people pay for YT premium now.

So if every user paid $1 per month, it might not pay all the costs but the admins could get paid something and the fediverse could scale. The bigger you get though, you get economies of scale from future Fediverse data centers, but also you need really good programmers because its a huge temptation for hackers and propagandists.

I also want to say its a labor of love and a lot of work for mods too who may be non technical but the work and time they put in is important.

Looking at just the hosting costs is actually a really bad indicator of total costs. The unpaid volunteer time just to run/manage the instance are likely going to be significantly more than the hosting costs if they were compensated even at minimum wage.

Each of the stacks for XXXiver.se and Bestiver.se (Mastodon + Lemmy + Static Site (+ Linkstack/Wiki for XXXiver.se premium)) are shoved into a Hetzner server at ~$13/month, and backed by R2 Object storage.

My current total hosting costs are ~$30/month to host 2xMastodon, 2xLemmy, 2xStatic Site, 1xLinkstack and 1xWiki. This is basically the minimum cost for me to host all of that on their own infra. I have approximately 0 users other than myself yet, so there's not really a useful cost/user and I can't really provide info on scaling.

Unlike most others here I'm seeing if I can make hosting into more of a job by selling the full suite of services to communities (e.g. get your own Mastodon + Lemmy + others) or by up-selling to premium accounts. I highly doubt that it will actually make any useful amount of money but I'm curious enough to try.

@seb@ioc.exchange publishes the costs for ioc.exchange:

Servers are hosted at Linode and hosting costs are around $300/month. Media files are hosted in AWS S3 and the costs are around $50/month. So in total our running costs are about $350/month.

Unfortunately the donations still don't cover it.

This is your regular reminder that our hosting costs are roughly $350 per month. In the last 30 days you all have contributed $216. Thank you very much for everyone who has contributed - You are awesome!

edit: User numbers from fedidb: 1,737 MAU, 26,315 total.

Lemmy.zip stats can be found here: Lemmy.zip

Our Admin gives us a monthly report. We are at 54$ while visitor count, rewlquest count can be seen at the report.

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).

I have my thinkcentre that I use as main PC on at all times, and it's basically free in the autumn/winter/early spring as its energy consumption serves as a heater. And orherwise I use it. So say 100 nights uh to be generous 1000h a year for what, 30watt so 30kwh at under 0.2€ equals say 6€.

I'm all alone on the server though so it costs 6€ a year per user I guess 😁

Beehaw's financial update https://beehaw.org/post/15866385

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.

We run on the cheapest Hetzner VPS we can, which is about $8 USD/month. Pictrs are on cloudflare R2. Pictrs storage hovers around 14GB and we have yet to get a non-zero invoice.

Our active users are super low (I think). I don't think the lemmy interface tells you the number of active users for in instance, just for communities, but since it's a niche instance I can safely say it's around 10 people.

So that's a little less than a dollar per month per user. On the existing VPS I think we could safely add a bunch of users without needing to upgrade.

About $50 monthly for server, backups, image hosting, mails etc.

wired.bluemarch.art runs on the cheapest Hetzner VPS, so €4.18 per month plus yearly domain cost. Right now there is only one active user on this instance so the price for an active user is a bit high, but I don't really care because I would pay for a VPS even when I don't run a Lemmy instance on it.

Is the shutdown about cost per user? why not just limit signups in a case like that? I sorta assumed some instances were personal instances with no real signups and some where more open public. I don't see why someone can't run something with the intention of carrying like 10 users max or 100 or 1000 or what not.
