As far as I understand it currently people host their own Lemmy instances just for the hell of it or out of the goodness of their heart
But the larger instances will end up costing more money and I’m doubtful that will be sustainable with no income
Alot of the larger instances have user donations set up so that the servers can be maintained, this is how lemmy.world works
You can do your part! I set up a recurring donation recently, recurring donations are much better for the sustainment of an instance since the owner knows they can keep running and not have to worry about intermittent donations.
Crazy-ish idea, but maybe Lemmy could make a feature where instances can have custom awards similar to Reddit gold and stuff, and users can buy them to both award posts they like and financially support the instance host
Hope not, trophies and award whoring is just as bad as karma whoring and neither is a thing here and lemmy is better off because of it.
Yeah I’d kinda rather stick to donations tbh
Users actually run a lot of larger instances on the Fediverse off of donations! I run a larger Mastodon server and we get literally double our monthly costs in donations. For every month we stay open, that is two months longer we stay open. Absolutely wild. We have about 1.5k users, with about 20-30 of them donating maybe $5-10 monthly. That’s 2%-ish of the user base donating. Lemmy is LEAGUES easier to host given that it’s written in Rust and is incredibly resource efficient. So I can only imagine it’ll be even cheaper to host on donations.
Larger instances will either have more donators or close their subscriptions if it really is unsustainable.
The more Lemmy grows, the more instances will show up, which will help spread the load.
You speak of sustainability but Lemmy survived the wave of incoming Redditors without much downtime. It’s really impressive that this growth could happen. That’s the power of decentralized systems: they scale!
One other thing I don’t see people pointing out is that Lemmy is basically a successor to classic web forums, so companies may run their own so they can have full control over the experience and moderation like for movies, series’s, or games, and in which case they would be more than happy to eat the cost of hosting. For example there could be a Lemmy.Disney.com instance to act as a Disney sanctioned discussion zone for their products where they could put tons of moderation rules in place.
I host my own. Specifically for myself and those who are friends or friends of friends.
I have a cluster of servers operating in my garage. Free real-estate for tons of stuff I want to host. I have to “pay” for electricity… the rest was already paid for long ago. My electricity cost for my whole cluster… is an estimated $1750 a year. But that cluster is 160 CPU cores, 750 GB of RAM, and ~400TB of storage. You ain’t getting that on a cloud hosted provider for $145 a month. About $110 of that is subsidized by my business operations. I host email, websites, nextcloud, plex, etc… boatloads of stuff.
You offer paid hosting with hardware in your garage? I’m getting dot-com flashbacks!
I actually do… Yes… I have dual internet connections, dedicated power off both phases of my electricity with ~5 hours of battery backup, run redundant internal infrastructure (power, network, and server hardware)… I also have a massive backup library and am currently working on obtaining offsite backups solution. The whole site/house is also monitored with cameras.
I have better uptime than some datacenters in my area have which I can truthfully quantify that as I also hold a CIO/CISO position in another company that operates out of a major Datacenter in my area.
Edit: Should clarify, an offsite backup solution that ISN’T “just peer with backblaze or some other provider” to store your backups. I intend to do a rotating tape library. With one set of tapes always being off site.
Also to mention… I have better uptime than AWS-east at this point of the year… Although there will be some outages of my infrastructure here soon for a network hardware update. I suspect something in the order of about 1 minute of downtime total.

Sadly, Just lost it :( I knew the switch upgrades would do it… Eh. One more set of switch upgrades (40gbps trunk) here soon and they’ll be fully redundant too.
How does load balancing work across this fediverse… if at all?
What kind of load balancing are you thinking about/looking for?
If we look at Lemmy in specific…
Jobs that a server performs for users on it’s platform:
Login services(are you even you to begin with?)
Session Management (being logged in at multiple places, not mixing you up with other users…)
Subscriptions (what content to even show you… organizing them on the page… etc.)
Ban lists (and applying them to what you’re looking at)
Peering with the other platformsJobs that a server performs for off platform users: Sending ActivityPub messages to the other user’s platform.(effectively the same as “peering with other platforms” from above)
The idea is that the jobs that the server has to do for it’s local users is actually a lot more both numerically and in taxing tasks than the jobs that one particular instance has to do to send updates to the federated instances… A lot of the list in the first case is a boatload of SQL queries. The activitypub notification is effectively a broadcast of a relatively simple text that doesn’t take much bandwidth.
So let’s look at actual cases now that we have some ideas of what instances are doing.
I run a small instance, I have a few users (because I purposefully keep it small). If my users only ever interact with the fediverse through my instance, then other instances don’t have to do most of the jobs in the top list. I’ve taken that load from lemmy.ml or other bigger instances that my users would have ultimately migrated to if they didn’t have my server. The tradeoff is that my few users now cost the 1 connection for activitypub notifications.
Lets look at a theoretical “perfect” setup… 2,000,000 users across let’s say 1,000 instances. Evenly distributed. So each instance has 2,000 users. In that case, any given server would have to serve 2,000 people from the upper list and 999 activitypub broadcasts. This is significantly easier to do than have a single server try to handle all 2,000,000 users on a single instance serving nothing to the activitypub broadcasts.
There’s is one caveat with this… activitypub broadcasts will send everything that is subscribed… even if users don’t actually view it. So there could be some waste. This then leads to the discussion of well how many users until there’s a breakeven in cost of the first list vs the potential waste of the activitypub bandwidth. That answer is debatable… But most people agree that take the discussion seriously that the return on investment could be as low as 2-5 users. I think that the bandwidth cost outweighs the SQL (CPU, RAM, etc…) costs quite handily personally.
Other useful functions that occurs with this setup… As long as I got the ActivityPub message on my server… my users can see all of Lemmy.ml’s content. Regardless of if Lemmy.ml is actually running or not. We saw that with the downtime that some of the bigger servers are seeing, all the other instances could still consume the content… Just no updates were being sent.
This is relatively simplistic… I’ve skipped some nitty gritty stuff… I’ve simplified some other stuff. But this is the gist.
Edit: Other functions that you need to think about that lemmy is accomplishing for local instance users… Notifications, saved posts, language filtering, settings, profiles, avatars, reporting, slur filters, moderation, NSFW filters… The top list is actually considerably larger… like I said we simplified.
Great explanation, thanks for the write up! I have a couple of questions, if I may.
-
So if I setup my own instance tomorrow, it’d be sending notifications of activity to all the other instances? Maybe I’d have to have a list of instances I’d like to notify? How does it discover the other instances?
-
If my instance is listening to all other instances? Won’t saving all posts take up a lot of disk space? I guess there is only text and link data and no media, but wouldn’t it add up fast as the number of users/instances grow ?

I started !programming.dev because I am a moderator of several 100k+ subs over on Reddit and I didn’t want my communities to not have a place to go if Reddit crashed and burned (even though it’s incredibly unlikely). The main sub I moderated (/r/ExperiencedDevs) for years wanted user verification to combat the spam that was newbies commenting and posting about things they didn’t really know or understand. This will be possible to actually implement on Lemmy, whereas reddit was closed source, and didn’t really care about their communities.
I am also a strong supporter of pulling control away from megacorps. We need more small to medium sized businesses on the planet.
For selfish reasons? I wanted to work on something new and have true ownership over it, the ability to build a community that worked together to build something without capitalism standing in the way. It might seem strange, but one of the first things I did was bring multiple other people on board to help me maintain the server, even going so far as to add domain managers to the domain name. This was all to counter the major questions people were asking around “what if the host decides they don’t want to host anymore?”. Well hopefully the programming.dev community is willing to take that burden if the time ever comes, even though I hope it doesn’t. I also wanted to start something similar to a coop, where ownership is shared, meaning users have incentives to make the platform better. I have lots of ideas around this, but this will never be possible on Reddit. It is quite feasible here.
I also had the chance to buy an incredibly dope domain name! https://programming.dev! Why wouldn’t I jump at that chance? And I get to even use it instead of let it flounder. So many reasons to host something like this, to build a trusting community, a safe space to have to let people talk about a shared love/topic/hobby.
Totally agree with the dope domain name. Not going to lie, a big reason for picking
programming.devwas to be /u/jim@programming.devThis will be possible to actually implement on Lemmy, whereas reddit was closed source, and didn’t really care about their communities.
Just curious how you think you might go about this. Do you plan on contributing yourself, forking, or using the community to influence the direction/prioritization of new features?
Honestly the domain name is a fantastic choice; Much easier to feel comfortable sharing links to my colleagues from programming.dev than something like “shit just works” or “lemmy world”
We run ours, because we are two trans women that are fortunate enough to be able to afford to run an instance that specifically prioritises the needs of our community. It’s a way of using our privilege to create safe community spaces
Fantastic. You go girls 🥰
I already host my own stuff for the most part: emails, DNS, NextCloud, IRC server, IRC client (ZNC, The Lounge), my website and a few other things.
I already pay like $50/mo for a dedicated server so that I have complete control over my data and my digital life, so adding a Lemmy instance to the mix is basically free. Just another VM among many of them, sharing the same resources as the rest of the stuff I host.
I share my server with a few friends, and pretty much my friends and their friends are all free to use my stuff as well. Been doing that for about 14 years at this point: always let my friends put their PHP sites on my server and whatnot. A dozen people using my IRC bouncers, a handful of people on my IRC server. When people need a game server sometimes I hand them out a VM to run the server for a while, then when they’re bored I turn it off and shelve it away. It’s a lot nicer to foot the cost of a service when it’s for people you know and care about.
I’m a FullStack + DevOps engineer as my day job, so it’s pretty trivial for me to set up and maintain. If anything it’s a bit relaxing compared to the insanity I deal with at work.
Regarding costs, the nice thing with distributed systems like Lemmy is that the average small to medium sized instance is really cheap to run. It’s when you run into scaling problems as you grow that becomes painful and often expensive if you can’t optimize the system. Suddenly you need way more servers, redundant databases, caching layers, spend a lot of time maintaining all of that, write automation to scale up more easily, etc.
Without federation, the whole ecosystem would go down, it puts a lot of pressure and a lot of need in maintaining reliability and performance. With federation, if my node goes down for a day or two, only a handful of users will complain about it, and all is well.
So in a way, many smaller instances distributes the cost of running the whole fediverse across many more people with much lower cost figures each, something one can afford to pay continuously even without taking in any donations. As I said, it cost me $50 for the whole server, but really I could probably run this on Oracle’s free tier forever and never pay a dime for my Lemmy experience.
I’m very new here and curious if I could ask as it sounds like you know what you are talking about.
My self hosting skills are extremely basic. I have an 8G Pi4 I run jellyfin, navidrome and a few other bits and bobs on. I’m scared of opening ports on my home network so use Timescale for external access. Could I run a personal Lemmy instance like this? Can I interact with other instances via Tailscale or do I need to actually open ports?
Resource wise what would a personal instance require in the cloud? Would something basic like a 512mb 10G droplet from Digital Ocean suffice?
You could use a Cloudflare tunnel if you really wanted to avoid opening ports, but basically as long as you only open the right ports for what you want to host and have a good firewall (I use OPNSense) you’re fine
You do need to allow incoming traffic, as the data is pushed to you by the remote server, not pulled from it.
As @Hexarei@programming.dev said you could however use Cloudflare tunnels and it would work just fine, it just needs HTTPS.
Experiment with it, have fun! Solving problems is how you learn that stuff 😃
Otherwise yeah the 512MB droplet should be alright to start off, that’s about what my instance uses.
I really like the overall concept of Lemmy, so I decided to set up lemm.ee to support the Lemmy network with my skillset. I have previously had the privilege of being responsible for running large platforms online (end-to-end, everything from operations to software engineering), and so far, this experience seems to be extremely relevant for running Lemmy in its current state.
As for paying for hosting, my initial plan was to to just pay for everything myself as kind of a hobby, but the userbase at lemm.ee has been very gracious in first asking me several times to share costs, and then actually sending money once I set up donations. I’m not sure yet if this donations-based funding will be sustainable, or if it will fall off after the initial hype dies, but for now it’s really awesome to see that there are several other people who believe in lemm.ee and want to share financial responsibility for it.
I’ve been hosting a gaming server plus other related stuff myself for some years now.
While the user base will definitely be different, relying solely on donations is unfortunately not sustainable long-term. Donations fluctuate massively based on time of year in my experience. So it’s always good to periodically remind your community that lemm.ee needs donations to survive long-term.
When I do those reminders, users come out of the woods in droves to donate. It’s less that they’re unwilling to donate and more that they just forget to donate.
That’s great! It’s kind of a crowdfunded instance, then. Makes me wonder if it would be feasible to implement some sort of collection box plugin or something…
Yes … if anyone is a developer looking for ways to provide value to the fediverse … I suspect the donation process is probably of high value.
I don’t know the best way for it to be done … but something so that it’s easy for users to setup a single or regular donation and easy for devs and admins to put the relevant button right into their platform … all so that whoever is willing to donate has every opportunity to do so.
Yes, and I know it’s counter to the core motivations of this movement, but probably need a centralized repository for donation that can be a universal door for funds that can then be distributed to vulnerable, but active, instances. Needs to be run by a collective of reps from instances meeting a minimum threshold of support for the community. Also needs to be nimble enough to revoke funding is an instance takes a hard evil turn.
Or maybe just an app/site that recommends a distribution of a set monthly amount (e.g. 30 bucks) to the instances you use the most as a user?
I don’t think we need that at all. Each instance can look after its own hosting and funding.
A centralised pot is asking for trouble - what about theft or corruption? What happens about disagreements like defederation? Seems a lot more trouble than it’s worth.
What does it actually cost? I have no basis for a ballpark guess even. I’ve seen this question asked to a number of admins and haven’t seen a direct answer.
It’s hard to judge how sustainable a donation based approach is without that info.
The costs will vary wildly depending on how the instance has been set up. If you set up all necessary services on a single VPS (as is the most common approach for smaller instances), then you can probably get by on $10-$20 a month. Splitting different services onto different servers, adding backups, load balancing, CDNs, redundancy, caches, etc will quickly increase the cost. Bigger instances need more powerful servers, that will increase the cost further.
On lemm.ee, we are currently not using very high-end servers, but we ARE using all the other things I mentioned above, and the monthly cost is currently hovering around $200 (that’s for 3 servers, a managed database, object storage, load balancing, a global CDN, and an e-mail provider). This is still on the very cheap side in the grand scheme of running online platforms, but definitely much more than I would want to pay for a single-user instance for example.
And honestly, 200 is on the high-end even with this setup. lemmy.dbzer0.com is way less
$200 is still on the low end, trust me - high end managed databases and compute resources are in the thousands, adding redundancy to that will double or triple it 😃
Ye if you’re adding like super redundancies etc sure. But I mean, it’s lemmy. We don’t need all that. My whole VM config is in ansible. I can literally scrap the whole thing, and redeploy it in 10 minutes. I just need to have a DB backup in case of some sort of catastrophic failure
IaC is awesome 👍 lemm.ee is deployed using Terraform.
My
lemmy_serverredundancy is mostly just so I can do infra changes without downtime (just take one node out of the load balancer, redeploy it and put the new one in), but it does also help a bit with general performance. I agree it’s not strictly necessary, the vast majority of other instances are just running on a single server, but I do think it’s very nice to have.For back-ups, I have point-in-time recovery, so I can restore the database to any random timestamp - and it has actually come in useful once already when two weeks ago I was able to restore to a good state about a few minutes after a problem - I think nobody even noticed that anything happened in that case 😃
I can’t thank you enough for sharing your knowledge, I am very interested in learning about server management and being able to read your thoughts is something I find extremely invaluable, please keep up with the great work! 😁
Problem with Terraform is it assumes cloud providers, which tend to be expensive (or at least, I don’t know a way to do terraform on hetzner dedis :D )
My solution is to get cheapskate VPS and dedis and loadbalance them as frontends. The VM request is manual, but I only have to do this once anyway. It’s what I’m currently doing with the AI Horde. Of course, that doesn’t help when there’s DB changes but still.
What object storage are you using btw? I’m thinking to move to R2 or smt since I’ve had good experience with them until now. Contabo’s is way cheaper but when I tried to use it for high-demand stuff it dropped dead on the spot. But it might be ok for Lemmy.
Yeah pretty much my setup. Full DB and pictrs backups uploaded to Backblaze B2 every few hours. Config files all backed up. Also send a copy to my home lab. Encrypted on the server before it gets sent out.
Worst case - we lose a few hours of data.
I keep about a week’s worth of backups on B2 (and 2 days on my home server) which is just over 200GB now. But that costs next to nothing on B2.
Maybe eventually if my instance grows more I might consider doing a replica DB on another server.
My total costs are like, $7.50 a month but I only have 15 actually active users. I don’t need to grow, but I’m willing to. If the costs increase too much I’ll ask for donations and if that stops covering things I’ll just close registrations. That’s the great part of not being a business chasing infinite growth.
I’ve loved the idea behind Lemmy since I first discovered. At first, I was using lemmy.ml, but then I saw the opportunity to provide a nice space and expand my sysadmin skills. Since there was no Portuguese instance yet, I thought why not create one?
Since then, I’ve met more people hosting Portuguese services and it has been great :DFor funding, I’m working on two ways: the typical donations and trying to secure support from local FOSS organizations. At the moment, the server costs are not prohibitive and there have been some donations already. I’ve also been talking to some of those orgs and it’s going well :)
This sounds encouraging, I hope your instance flourishes
Thank you! :3
I don’t see why an instance couldn’t go with ads and subs or awards the same way Reddit does.
Because they’d probably have to create that tech themselves. Not that they won’t but it’s not there ATM afaik
Id go ahead and open a feature request for it on their github. Id be supprised if they wernt open towards the idea given they run one of the largest instances themselves
See this is good. The more the fediverse grows the more people find out what us old users have known for years and years:
You don’t need to rely on large tech companies. The web is for everyone.
It is pretty wild to think about how many people only know the internet as about 5 websites or apps…
To have some control over my data and for the fun of it. With money? Selfhosting to me is a hobby and it has also taught me a lot, some of which has been helpful on my career.
I host my own because it’s cheap, less than 10 dollars per month, and I wanted to contribute to the growth of the Lemmy community.
Also turns out that it’s another benefit to this: I don’t have to get involved in the entire political debate of who federated with who. I just subscribe to communities I want anywhere.
I’m thinking about it. Do you need a domain name as well?
Yes you need a domain but that is usually quite cheap
Or use the raw IP :-D ?
You do need valid TLS and a cert can’t be directly issued on an IP.
Yep you need a domain name pointing to your instance when you run the installation of Lemmy and it will create a let’s encrypt https cert for your site automatically.
In the medium term I’m confident costs could be met using patreon or something similar for large instances.
Plenty of people willingly paid for reddit awards etc. I think most of us feel more loyalty to Lemmy than reddit in the light of recent events.
i Have a homelab, i work and design computer/server/linux/security solutions for enterprises from my home. Lemmy is just another docker process in my lab.
This will also be the case for me eventually, once I get around to setting up a Lemmy instance it’ll just be joining all the other stuff already in my lab k3s cluster
I have a 4 core 24 GB ARM VPS on that Oracle free tier that I use to self host some personal services.
I just think it’s neat.
What’s the catch? How long does the free tier last?
There’s always a catch. Oracle has and will claw back that free allowance unless you meet specific criteria or move to a pay-as-you-go tier with a cc on file with a $100 authorization charge, and even then they may. Ask me how I know lol
Or they’ll just shut it down with no explanation whatsoever, even if you’ve met all of their weird criteria.
There are two classic blunders. The most famous is “never get involved in a land war in Asia”, but only slightly less well-known is this: “Never go into business with Oracle when anything of value is on the line”.
Never go into business with Oracle when anything of value is on the line
Truer words have not been spoken.
That’s not even considering that you’re not going to be able to talk to a rep about it, or appeal that claw back in any way. Hell they’ll even terminate your whole account without warning, not just the VM. If I found out the admin of the Lemmy instance I’m using was hosting it on Oracle I would delete my profile immediately without a second thought.

Agreed. I still feel dirty for taking Google’s side in that ridiculous lawsuit Oracle filled after buying Sun. Only Oracle would try to make money from licensing fees for APIs…wait a minute…has Spez been talking to Elon Musk AND Larry Ellison?
One other catch is that is an ARM instance
Oh shit really? You get that much processing power for free? I gotta sign up to that
Except that the instances are usually full. There is hope, but not much
Me too, works well!
is this a dedicated vm or something else?
I do because I want to control my data and it runs on a VPS that also serves as my email server, amongst other small things. I pay about $20 USD a month which is nothing to keep my data from grubby hands. Though I must admit it was a lot of work getting my mail server running smoothly and it requires some tlc every now and again.
Mind going into some details about what you’re selfhosting overall?
Here’s one perspective: https://runyourown.social/
Personally, I run a Mastodon+Hometown server for around 100 people and it costs me about $30/mo. It costs me more to fill my car’s gas tank. I could maybe start a patron or something, but at this stage, it is not even necessary.
About 3 years ago, I was a member of r/ChapoTrapHouse, which got banned from Reddit. The day after this happened, we had over 10,000 people sitting in a lifeboat Discord “server.” Within the community, we had the experience and willpower to take Lemmy, kick the tires, make a couple adjustments which were necessary for our community, and make sure we weren’t doing malpractice by hosting it. This all happened before Federation had been implemented in Lemmy.
Maintaining the fork was labor intensive, and a lot of the original developers burned out. We couldn’t afford wages for development (the site still only exists due to volunteers), but the hosting costs were easily covered by user donations.
I never knew CTH got banned from Reddit, holy shit. Y’all out there doing the lord’s work supporting your community like that. Seriously, hats off :)
