Caddy vs Nginx Proxy Manager: 5 Best Reasons to Switch

I burned an entire Saturday migrating my homelab from Nginx Proxy Manager to Caddy, and about twenty minutes in I texted a friend “why didn’t anyone tell me it was this easy.” Then I spent the next hour second-guessing myself because NPM had never actually failed me — I just wanted fewer clicks. If you’re standing at that same fork wondering whether Caddy vs Nginx Proxy Manager even matters for your setup, the honest answer is: it depends entirely on how you like to work, not on which one is “better.”

This isn’t a benchmark flex-off — both tools push HTTPS traffic to your self-hosted apps just fine on homelab-scale hardware. What actually matters is whether you want a point-and-click dashboard or a three-line text file, whether you’re chasing automatic certificate renewal without thinking about it, and whether you’re running five services or fifty. Pick wrong and you’ll spend a weekend migrating later, just like I did — except I did it by choice, and you can skip that step by reading this first.

What Caddy and Nginx Proxy Manager Actually Do

Both tools solve the exact same problem: you’re running a pile of self-hosted services — Jellyfin on port 8096, Home Assistant on 8123, Vaultwarden on some other random port — and you want to reach all of them through clean subdomains with real HTTPS certificates instead of memorizing a spreadsheet of ports. A reverse proxy sits in front of everything and routes traffic based on the domain name, handling TLS termination so your apps don’t have to.

Nginx Proxy Manager (NPM) is a web UI wrapped around nginx. You get a dashboard where you add a “proxy host,” point it at an internal IP and port, flip a toggle for SSL, and you’re done — no config files, no CLI. Caddy is a standalone web server built from the ground up around automatic HTTPS. You write a domain name and a target in a plain-text Caddyfile, and it handles certificate issuance, renewal, and HTTPS redirects without you touching anything else.

If you’ve already read our Nginx Proxy Manager homelab SSL guide, you know NPM’s certificate workflow in detail — this post is about deciding whether NPM is even the right tool for you in the first place, before you get to that setup stage.

The Spec-and-Feature Comparison

Here’s the side-by-side breakdown people actually search for before picking one:

Feature Caddy Nginx Proxy Manager
Interface Text-based Caddyfile config Web dashboard GUI
Automatic HTTPS Built-in, zero-config for public domains One-click Let’s Encrypt toggle per host
Setup time (first service) ~5 minutes (edit Caddyfile, reload) ~10 minutes (deploy container, log into UI)
Config backup Single text file — trivial to Git SQLite DB export/import
Learning curve Low, but requires comfort with text config Lowest — no CLI or files needed
Resource usage Very light (single Go binary) Light (nginx + Node.js backend)
Best for Devs comfortable with text config who want minimal fuss Beginners and GUI-first homelabbers

Where Caddy Wins

Caddy’s whole reputation rests on one thing: automatic HTTPS that actually works without you thinking about it. It ships with a built-in ACME client for Let’s Encrypt and ZeroSSL, so the moment you point a domain at it, a certificate gets issued, renewed roughly 60 days before expiry, and reinstated automatically if something goes wrong. There’s no toggle to remember, no renewal job to babysit.

The other underrated win is the config file itself. A working Caddyfile for a single reverse-proxied service is genuinely three or four lines:

jellyfin.yourdomain.com {
    reverse_proxy 192.168.1.50:8096
}

That’s it — no upstream blocks, no location directives, no manually configuring SSL certificate paths. Compare that to an equivalent raw nginx config and Caddy’s version is genuinely 3-5x shorter for the same result. Because it’s just a text file, backing it up is as simple as committing it to a Git repo, which makes disaster recovery almost boring.

What I liked: Automatic cert renewal I never have to think about, config that fits on one screen, and a tiny resource footprint on constrained hardware.
What could be better: No GUI at all — every change means editing a file and reloading. That’s a dealbreaker for some people, and a non-issue for others.

Where Nginx Proxy Manager Wins

NPM’s entire pitch is removing the text file from the equation. You deploy the Docker container, log into the web dashboard, click “Add Proxy Host,” type in a domain and an internal IP:port, flip the SSL toggle, and you’re serving HTTPS traffic. There’s genuinely no learning curve — you don’t need to know nginx directive syntax, you don’t need to SSH in to make a change, and you don’t need to remember what you configured six months ago because it’s all visible in the UI.

That matters more than people give it credit for if you’re new to self-hosting or if multiple people in your household need to touch the proxy config. It’s also why most “start your first homelab” guides point beginners at NPM before anything else — the GUI removes the single biggest source of reverse-proxy anxiety, which is “did I just break HTTPS for everything.”

If you’ve already got NPM running and just need the SSL side dialed in — wildcard certs, DNS challenges, forcing HTTPS redirects — that’s exactly what we cover in the Nginx Proxy Manager homelab SSL configs guide. This post is about the “which tool” decision; that one is about getting the most out of NPM once you’ve made it.

What I liked: Zero CLI required, visible history of every proxy host, and SSL certificates are a checkbox instead of a config block.
What could be better: Every new service needs a manual GUI entry — there’s no auto-discovery, so it doesn’t scale as gracefully as Caddy or Traefik once you’re running 20+ containers.

Caddy vs Nginx Proxy Manager: So Which One Should You Run?

If you’ve never set up a reverse proxy before and you want to see results in the first ten minutes without opening a text editor, start with Nginx Proxy Manager. It’s forgiving, visual, and you can always migrate to Caddy later once you’re comfortable with the concepts — nothing about starting with NPM locks you in.

If you’re already comfortable with basic config files (even just editing a docker-compose.yml), or you’re tired of clicking through a UI for every new service, Caddy is going to feel like a weight lifted. The automatic HTTPS alone is worth the switch for anyone who’s ever had a certificate silently expire and take down access to their own dashboard.

Whichever one you pick, both run comfortably on genuinely tiny hardware — this isn’t a workload that needs a beefy server. A low-power mini PC or a small NAS with a spare Docker slot is more than enough to run either one 24/7 without breaking a sweat.

The Hardware to Run Either One On

Both Caddy and Nginx Proxy Manager are lightweight enough to run as a single Docker container using a sliver of CPU and RAM, which means the hardware question isn’t really about horsepower — it’s about reliability and always-on power draw. Two options I’d actually put in a cart:

For a dedicated, always-on box that just runs your reverse proxy (and probably Pi-hole, Vaultwarden, and a handful of other lightweight containers alongside it), the GMKtec NucBox G3 Mini PC (Intel N100, 16GB RAM, 1TB SSD) is close to ideal. It idles at a few watts, has a 2.5GbE port so your proxy isn’t the network bottleneck, and has more than enough headroom to run either Caddy or NPM plus a dozen other lightweight services without ever feeling the load.

If you’d rather consolidate your reverse proxy onto the same box that’s already holding your media library or backups, a small NAS works too — most support Docker natively these days. The Synology DS224+ 2-Bay DiskStation runs Container Manager out of the box, so you can drop Caddy or NPM straight onto it instead of buying a separate box just for reverse proxying.

Synology 2-Bay DiskStation DS224+ (Diskless) 2-bay; 2GB DDR4 DS224+
  • Centralized Data Storage - Consolidate all your data for complete data ownership and multi-platform access
  • Sharing and Syncing Across Systems - Access, share, and sync data across different systems and devices using intuitive controls

If you’re weighing mini PC options more broadly for your homelab, our best mini PC for home server picks covers the wider field, and if you want dedicated NAS storage instead of just a compute box, the best NAS hard drives roundup pairs well with either the DS224+ or a DIY NAS build.

A Quick Reality Check on Performance

You’ll see benchmark posts claiming one is meaningfully faster than the other, and technically nginx (NPM’s backend) does have a slight edge in raw throughput under extreme load. In practice, at homelab scale — a handful of people streaming Jellyfin, checking Home Assistant, and syncing Vaultwarden — that difference is completely invisible. Neither tool is going to be your bottleneck; your home internet connection will hit its limit long before either reverse proxy does.

For the technical deep-dive on how Caddy’s automatic HTTPS actually works under the hood — ACME challenges, OCSP stapling, and certificate storage — the official Caddy documentation is worth a read if you want to understand exactly what’s happening behind that one line in your Caddyfile.

The Takeaway

The Caddy vs Nginx Proxy Manager decision really comes down to how you want to spend your maintenance time: NPM trades a little scalability for a dashboard that removes all the guesswork, while Caddy trades a text file for automatic HTTPS that just works and a config you can drop into Git in thirty seconds. Neither one is wrong, and neither one is a permanent commitment — plenty of homelabbers start on NPM and migrate to Caddy six months later once they’ve outgrown the GUI.

Pick the one that matches how you actually want to spend your Saturday: clicking through a dashboard, or editing a three-line file. Either way, you’ll have clean HTTPS subdomains for every service in your homelab by dinner.
