Selfhosted
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.

Thank you for the wonderful comment!
The only reason I'm looking to host in Europe is because of the prices: this server will not allow for sign-ups (i.e. it will only be for me). I will likely only need 1GB of RAM and very little CPU power to get this to work. The prices in Europe for low-cost VPSes are better than in the US. I don't actually care about which country/continent I'm hosting it in, this decision was purely financial.
I have a question: I believe I can set Lemmy to auto-sync content from communities I'm interested in (I can set the frequency for the auto-sync) - would it be possible for Cloudflare to cache the content if it is already in the database of my Lemmy instance? I know that CDNs can only really cache static content but I do not know enough about CDNs/Cloud Networking in general to be able to figure out just what it would be able to cache.
Thank you, yes I had the protections offered by Cloudflare in mind when I asked this question. I do not plan to do anything illegal so I hope I'll be fine.
Could you also tell me why Cloudflare asks me to change the authoritative nameservers on my registrar's page to their nameservers? I think my networking is getting a bit rusty, I really can't figure it out.
One more thing; is there a difference in configuring a Cloudflare CDN vs a Cloudflare reverse-proxy for a VPS instance? I see people in c/homelab talk about this but I never really delved into it, but if I could access my network remotely using this it would a great bonus.
Thanks!
Adding to the hetzner comment: I think AWS has free very crappy servers. If you're a student, the Github Student Pack has free digitalocen credits.
In theory, cloud flare could pre-cache content before you request it. Unfortunately, that would require significant effort from Lemmy to let cloud flare know that there is new content, and then it would be up to cloud flare to decide to cache it for 1 client. Both these things aren't happening.
CF needs to dynamically control where requests for your server end up, and for that they need to be the authoritative DNS for it.
Cloud flare indeed acts as a reverse proxy (because that's how CDNs work), but unlike a self-hosted reverse proxy, theirs will be on their servers, so will not have much more more access to your network than yourself outside of it. I think they have some sort of offering to actually give your more access, but A) idk if that's free and B) that requires an always-on computer in your local network, at which point why not just host your Lemmy instance on it?
Another option for very cheap VM, storage, bandwidth: Oracle Free Forever
https://www.oracle.com/cloud/free/
Wasn't aware of that since I both have my own server and happen to despise oracle but good for people who need cheap compute!
Thank you for your comment!
I am opting for the very low cost providers like Racknerd and CloudServer (see: $1 VPS offerings) - which host most of their servers outside the US.
Thank you for the explanation, I would like to know more about the "effort" from Lemmy's side to let Cloudflare cache content before it is requested.
Could you explain this point a bit more? Why would Cloudflare need to control DNS for my domain? How is this linked to them proxying my traffic? I've been trying to understand this for a bit now - how does having CF's own nameservers let CF proxy my traffic?
I was also considering hosting Lemmy in my own network, but I can't seem to find any guides on which ports to forward - if I could just find a decent guide on the networking required to host Lemmy I might even do it on-prem.
Thanks a bunch!
Using Cloudflare nameservers helps to proxy your traffic because if proxying is enabled ("orange cloud") those servers aren't handing out your IP address to people who request your domain, they're handing out addresses belonging to Cloudflare machines near the visitor instead. They have machines in data centers all around the world, and they would like the traffic to end up in the data center closest to where it's needed.
Doing that means they can do stuff like reduce cross-region network traffic: for instance, if your VPS is in Europe but a bunch of visitors from the US suddenly request a certain image on your site (because you've just posted to a popular community, perhaps), they only need to have that image data cross the Atlantic once before they can serve it up many times in the US. Besides saving bandwidth that also allows it to be served faster to most visitors, because most requests for it are effectively served from a local data center instead of from one on another continent. They'll also continue to be able to serve your image even when your VPS is down for whatever reason, as long as it's already in cache.
(Most of that is probably oversimplified and but hopefully that clarifies it a bit)
Hetzner (a popular European host) now has US locations and their pricing is really good. Look for hetzner.com - which is in English instead of hetzner.de, their native German site.
