What you should not self-host to save money

Lots of guides list what to self-host. Few tell you where it backfires, so here's that list.

Self-hosting really does save money on media, photos, files, passwords, and ad blocking. A few things cost you more in time, risk, or reliability than any subscription would. These are the ones I'd leave alone:

Words you'll see in this guide
  • Self-hosting: running an app on your own hardware at home instead of paying a company to run it for you.
  • RAID: storing data across several drives so one can fail without losing anything. It protects against a dead drive, and it isn't a backup.
  • 3-2-1 backup: three copies of your data, on two kinds of storage, with one copy somewhere other than your house.
  • Opening ports: telling your router to let outside internet traffic reach a device in your home.
  • VPN: a private, encrypted tunnel between devices over the internet.

1. Email

Running your own mail server looks easy and isn't. Big email providers often flag mail from small home servers as spam, so your messages can quietly fail to arrive, and you may never find out.

You'd also be responsible for spam filtering, security updates, and keeping your server's reputation clean, forever. A proper email host does all of it for a few dollars a month. Nearly every experienced self-hoster tells beginners to skip this one.

2. Your only off-site backup

A home server is one copy of your data in one place. RAID doesn't change that. It protects you from a dead drive, and does nothing against fire, theft, flood, ransomware, or deleting the wrong folder.

The 3-2-1 rule still applies. Self-host your main copy, and pay a few dollars a month for a cloud copy outside your house.

3. Anything on the internet you can't keep secure

Putting an app on the open internet when you can't keep it updated and locked down is a risk that can cost far more than a subscription. If you want to reach your server from outside, use a private VPN like Tailscale instead of opening ports. Don't run public-facing apps you won't maintain.

4. Services where the paid plan is cheap or free

Self-hosting has a cost people forget: your time. Add electricity and the occasional late-night fix. If a service is free or a couple of dollars a month, trading it for an app you now have to update, back up, and fix is usually a bad deal. Save self-hosting for the subscriptions that add up, like the $10 to $15 a month ones.

5. Important things with no fallback

Running your smart home on Home Assistant is great. If a door lock, a security camera, or your family's only calendar depends on a box that might crash while you're away, plan for the day it's down. You can self-host these. Just don't set them up so one failure locks you out.

My rule:
  • Self-host to save money and gain privacy: media, photos, files, passwords, ad blocking, and home automation.
  • Keep paying for the few things that are better rented: email, an off-site backup, and anything you can't secure or maintain.
Knowing the difference keeps self-hosting fun instead of a second job.

So what should you self-host?

The apps that save money and run reliably: Jellyfin for media, Immich for photos, Nextcloud for files, Vaultwarden for passwords, and Pi-hole for ads.

Quick answers

What should you not self-host?

For beginners: email, your only off-site backup, and anything on the open internet you can't keep secure. Also skip services where the paid plan is cheap or free and the time cost is higher than the savings. Self-host media, photos, files, and passwords instead.

Why shouldn't I self-host my own email?

Big email providers often flag mail from small home servers as spam, so your messages can quietly fail to arrive. You'd also handle spam filtering, security updates, and your server's reputation forever. A proper email host does it better for a few dollars a month.

Does a home server count as a backup?

No. Even with RAID, it's one copy in one place, and a fire, theft, ransomware, or a wrong delete can take all of it. Follow the 3-2-1 rule and pay for an off-site cloud copy.

Is self-hosting actually worth it then?

Yes, for the right things. Media, photos, file sync, passwords, ad blocking, and home automation save real money and improve privacy. Knowing what not to self-host lets you spend your time where it pays off.
