How much value can ONE domain purchase actually give me?

The domain

Alright Alright Alright. This post might come across as an advertisement for Cloudflare. I think a good product markets itself. This is sort of what's happening here. Right now, I use the domain: yasirsgarage.org for 3 things. All of which have incredible value.

What I've built on top of it

None of the three things above are really about the domain itself, they're about what having one lets you glue together. A domain is just a name Cloudflare will let you point wherever you want, and once you have that, three unrelated problems all get solved by the same trick:

• A public face for the homelab. The portfolio site you're on right now sits behind a Cloudflare tunnel, so my home server never has an inbound port open to the internet, Cloudflare terminates the connection and tunnels it back to me. Free, and I get DDoS protection and TLS I didn't have to configure myself.
• A private, memorable front door for everything else. Pi-hole handles local DNS and forwards any *.yasirsgarage.org request to Traefik, which routes it to whatever service actually needs it. So instead of memorizing which port 192.168.x.x I bolted a service to six months ago, I just go to service.tail.yasirsgarage.org, on my LAN or over Tailscale, and it's already wearing a valid HTTPS cert.
• Email that isn't tied to a provider. SimpleLogin sits behind the domain and generates aliases that forward to my real inbox, which I keep off the internet entirely. [email protected] on the contact page is a real, working alias, replying from it looks exactly like replying from that address, and if it ever gets spammed into oblivion I delete the alias and mint a new one. My actual email address never has to touch a public page.

Three completely different pieces of infrastructure, tunneling, reverse proxying, and email routing, all hanging off one domain name.

The value breakdown

My domain costs 10 bucks a year. It is one of the cheapest recurring costs in this whole home lab, and it's doing the job of several things that would otherwise each need their own solution:

• Without it, exposing the portfolio publicly means either opening a port on my home router directly (no thanks) or paying for hosting somewhere else. The tunnel gets me public hosting on my own hardware for the price of the domain alone.
• Without wildcard DNS through Pi-hole and Traefik, every self-hosted service either lives at a raw ip:port I have to remember, or needs its own manually-issued TLS cert. Traefik handles certificates automatically off the one domain, so adding a new service is "give it a subdomain," not "go set up TLS again."
• Without the domain, email aliasing tools like SimpleLogin have nothing to alias against, I'd be handing out my real address (or a generic Gmail alias that looks exactly like everyone else's) on a public contact page.

Add it up and one domain is quietly subsidizing hosting, networking, and email privacy, three categories that would otherwise be three separate bills or three separate compromises.

Would I do it again

Immediately, and it'd be one of the first things I'd set up in any home lab from scratch. It's not flashy the way a new server or a new self-hosted app is, but almost everything else I've built leans on it existing. Pull the domain out and the tunnel, the reverse proxy, and the email aliases all stop making sense at the same time.
