Mid 2022, a friend of mine helped me set up a selfhosted Vaultwarden instance. Since then, my “infrastructure” has not stopped growing, and I’ve been learning each and every day about how services work, how they communicate and how I can move data from one place to another. It’s truly incredible, and my favorite hobby by a long shot.
Here’s a map of what I’ve built so far. Right now, I’m mostly done, but surely time will bring more ideas. I’ve also left out a bunch of “technically revelant” connections like DNS resolution through the AdGuard instance, firewalls and CrowdSec on the main VPS.
Looking at the setups that others have posted, I don’t think this is super incredible - but if you have input or questions about the setup, I’ll do my best to explain it all. None of my peers really understand what it takes to construct something like this, so I am in need of people who understand my excitement and proudness :)

This seems like work but from/for home.
me after 15 years of intermittent learning self hosting:
i have the one random office PC that runs minecraft
…yeah that’s it
I’ve seen Caddy mentioned a few times recently, what do you like about it over other tools?
I can answer this one, but mainly only in reference to the other popular solutions:
- nginx. Solid, reliable, uncomplicated, but. Reverse proxy semantics have a weird dependency on manually setting up a dns resolver (why??) and you have to restart the instance if your upstream gets replaced.
- traefik. I am literally a cloud software engineer, I’ve been doing Linux networking since 1994 and I’ve made 3 separate attempts to configure traefik to work according to its promises. It has never worked correctly. Traefik’s main selling point to me is its automatic docker proxying via labels, but this doesn’t even help you if you also have multiple VMs. Basically a non-starter due to poor docs and complexity.
- caddy. Solid, reliable, uncomplicated. It will do acme cert provisioning out of the box for you if you want (I don’t use that feature because I have a wildcard cert, but it seems nice). Also doesn’t suffer from the problems I’ve listed above.
In addition to the other commenter and their great points, here’s some more things I like:
- ressource efficient: im running all my stuff on low end servers, and cant afford my reverse proxy to waste gigabytes of RAM (kooking at you, NPM)
- very easy syntax: the Caddyfile uses a very simple, easy to remember syntax. And the documentation is very precise and quickly tells me what to do to achieve something. I tried traefik and couldn’t handle the long, complicated tag names required to set anything up.
- plugin ecosystem: caddy is written in go, and very easy to extend. There’s tons of plugins for different functionalities, that are (mostly) well documented and easy to use. Building a custom caddy executable takes one command.
What is the proxy in front of crowdsec for?
If you’re referring to the “LabProxy VPS”: So that I don’t have to point a public domain that I (plan to) use more and more in online spaces to my personal IP address, allowing anyone and everyone to pinpoint my location. Also, I really don’t want to mess with the intricacies of DynDNS. This solution is safer and more reliable than DynDNS and open ports on my router thats not at all equipped to fend off cyberspace attacks.
If you’re referring to the caddy reverse proxy on the LabProxy VPS: I’m pointing domains that I want to funnel into my homelab at the external IP of the proxy VPS. The caddy server on that VPS reads these requests and reverse-proxies them onto the caddy-port from the homelab, using the hostname of my homelab inside my tailscale network. That’s how I make use of the tunnel. This also allows me to send the crowdsec ban decisions from the homelab to the Proxy VPS, which then denies all incoming requests from that source IP before they ever hit my homelab. Clean and Safe!
Thanks, but I meant the HAProxy in your homelab.
Remeber, the more boxes you have, the more advanced you are as an admin! Once you do his job for money, the challenge is the exact opposite. The less parts you have, the better. The more vanilla they are, the better.
Absolutely! To be honest, I don’t even want to have countless machines under my umbrella, and constantly have consodilation in mind - but right now, each machine fulfills a separate purpose and feels justified in itself (homelab for large data, main VPS for anything thats operation critical and cant afford power/network outages and so on). So unless I find another purpose that none of the current machines can serve, I’ll probably scale vertically instead of horizontally (is that even how you use that expression?)
