I rent a vps to run fediverse instances. Here's what I've found
Hi everybody! I rent a vps with 6 cores, 16 GB ram and 100 GB nvme to run fediverse instances (mastodon, lemmy, matrix, peertube) and a couple related services (nginx proxy manager, nodebb forum, wiki.js, uptime kuma, portainer, tig-stack).
The why
Over the past month they have been running. It has been some work to set them up but since then they run pretty flawlessly. My main goal was to find out how much hardware I really need to run private instances (just me or maybe a handful of friends).
Here are the stats:
Disclaimer: I checked and all services federate correctly.
Resource usage
From my point of view, the 6 cores are totally overkill. A two core would probably suffice. Of the 16 GB of ram I currently need 4. So 8 should suffice. The 100 GB nvme drive is barely handling it (66% full) and thats without backups (they get pulled immediately and then deleted) and with a 48 hour media delete cycle on mastodon (which currently is the largest folder I have).
Individual Space usage (nvme)
- 8.0K heimdall
- 2.0G lemmy
- 7.1G mastodon
- 5.2G matrix
- 123M nodebb
- 236M npm
- 3.5G peertube
- 12K pgadmin
- 8.0K portainer
- 376K tig-stack
- 8.0K uptime-kuma
- 8.0K watchtower
- 12K wiki.js
- 3.6G wordpress
So while I use lemmy the most, mastodon uses far more disk space, matrix also uses more than lemmy although I'm in like 20 chats and my friends don't use matrix except to chat with one another. I have subscribed to maybe 50 communities on lemmy.
Since the graphs in the screenshots lack legends, I'll explain the spikes.
Container CPU usage
- red spike: lemmy postgres
- lightblue: mastodon sidekiq
- yellow: telegraf
- dark-blue: lemmy ui
Container Ram usage
- red line: peertube
- light-blue: mastodon sidekiq
- dark-red: lemmy postgres
- pink: mastodon postgres
Summary
So far I didn't actively try to get the needed resources down except mastodon since I didnt want it to derail my experiment.
Mastodon seems to have the worst data on drive footprint, Peertube seems like a constant ram hog and lemmy spikes in the cpu all the time. So they all have their positives and negatives but nothing major. If you have 2 cores, at least 6 GB of ram and probably 250 GB of disk space to spare you should be good.
I'll work on making the compose files and config files publicly available but right now I'm not there. If you need help spinning up an instance, please let me know. I can send you individual files if needed.
Have a good one! :)

Interesting read! Can I ask how much running this approximately costs?
Looking at DigitalOcean, a similar ish Droplet would be around $100/mo.
At Hetzner, a similar ish shared host would be around €30–40/mo, or dedicated for €50–60/mo.
Not sure where OP is hosting, but they may have gotten cheaper.
On Hetzner, if you go with OP’s recommendation of 2 vCPU, 8 GB of RAM, and do the storage add on for 100 GB of bulk storage, it’d be about €16/mo.
I pay around 10$ per month atm. But you need to factor in backups which I handle with my home server. Those can be acquired as cheap as 2$ a month I believe. It’s not expensive if you know where to look and dont mind making mistakes.
That's way less than what I pay to vultr for a less powerful VPS to host my own set of services (lemmy, gotosocial, gitea). I gotta find a cheaper host 🙃.
Check out https://serverhunter.com. They’re good. But keep an eye on backups.
I am also interested in the answer to this and which service the author is using.
I think I found them on serverhunter.com or similar. Just search for serverhunter and you should find many interesting offers. The important part is that a good backup procedure is more important than strong hardware.
