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.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

I've never done any sort of home networking or self-hosting of any kind but thanks to Jellyfin and Mastodon I've become interested in the idea. As I understand it, physical servers ("bare metal" correct?) are PCs intended for data storing and hosting services instead of being used as a daily driver like my desktop. From my (admittedly) limited research, dedicated servers are a bit expensive. However, it seems that you can convert an old PC and even laptop into a server (examples here and here). But should I use that or are there dedicated servers at "affordable" price points. Since is this is first experience with self-hosting, which would be a better route to take?

When talking about hardware, the physical computer itself, a "server" is commercial grade and designed to run under heavy loads for years on end with very high reliability. Error correcting RAM, redundant power supplies, room inside for huge processors, more airflow than a C-130 for cooling, etc.

On the software side, a "server" is just a computer that provides some service to users on a network. You very likely have one of those Wi-Fi router/ethernet switch things from the likes of Linksys or whatever, right? That is almost certainly acting as a DHCP server for you LAN, in that capacity it might handle kilobytes of data a day because dynamically assigning IP addresses on a household Wi-Fi network is not a very demanding task, so it'll do it on a tiny little ARM processor with a few MB of RAM. It probably also has a web server, which is how the "go to its IP address in your browser and get to your router settings page" works. It's serving a little website that most of the time gets absolutely zero traffic.

So, turning a desktop PC into a "server." The question is, what services will it provide? Desktop PCs are pretty good at mostly low traffic with bursts of intense work, so if they're going to sit still doing nothing while you're at work all day, and then maybe handle some file storage or media transcoding during the evenings while you're home, a PC will do that just fine, if you're okay paying the power bill of having a computer up and running all the time.

If you're hosting a website or a game server with a lot of active users around the clock, you might want to look into more professional hardware.

Honestly, that's going to be pretty far down the road. Use what you've got, and fix issues as you go. Professional hardware is rarely needed, but it is pretty cool.
