Nginx Proxy Manager vs Traefik

Every self-hosted stack eventually needs a front door: one thing that takes requests on ports 80 and 443, sorts them by hostname, terminates TLS, and hands each one to the right app behind it. Nginx Proxy Manager and Traefik both do that job well, so the real decision is not which proxies faster — it is how you want to tell it what to do. One gives you a point-and-click web UI; the other configures itself from the containers it watches. That single difference in philosophy drives everything else.

Two ways to describe your routes

Nginx Proxy Manager (NPM) wraps a real Nginx server in a friendly Node.js admin UI. You add a "proxy host" in a form — type the domain, the internal address and port of the app, tick a box for a Let's Encrypt certificate — and it writes the Nginx config and fetches the TLS cert for you. Nothing about the underlying app has to change; NPM does not care whether the target is a Docker container, a VM, or a service on another machine, as long as it can reach the address you typed.

Traefik takes the opposite approach. It is a single Go binary that watches a provider — most commonly the Docker socket — and builds its routing table from container labels. You do not add a route in Traefik; you add labels to the app's container, and Traefik notices the new service and starts routing (and provisioning TLS) for it automatically. There is no UI form to fill in, and for many people there is no per-app config file either — the description of each route lives next to the app it belongs to.

Auto-discovery is the real dividing line

• NPM: explicit and manual. Every route is something you deliberately add in the UI. That is more clicks as your stack grows, but it is also completely transparent — the list of proxy hosts in front of you is the config, and there is no magic to reason about.
• Traefik: automatic and dynamic. Spin up a container with the right labels and it is live; tear it down and the route disappears. In a Docker-heavy setup where services come and go, this is a genuine productivity win — you stop touching the proxy at all after the initial setup.

Neither model is wrong. The question is whether you would rather manage routes in one place (NPM) or co-locate them with each service and let the proxy keep up on its own (Traefik).

Certificates, and everything past the basics

Both handle automatic HTTPS with Let's Encrypt, including DNS-01 challenges for wildcard certificates, so on the core promise of "clean domains with valid TLS" they are even. The gap opens on the advanced edges. Traefik has the deeper toolbox: rich middleware chains (auth, rate limiting, header rewriting, redirects), native support for providers beyond Docker, and first-class metrics for observability. NPM covers the common cases — custom Nginx snippets, access lists, basic auth, and the standard security headers — through its UI, which is plenty for most home and small-team setups but stops short of Traefik's dynamic middleware model.

Setup effort and resources

This is where the beginner-versus-power-user split is starkest. NPM is rated 1 / 5 to stand up: bring up one container, open the admin UI on port 81, log in, add your first proxy host, and you have HTTPS in minutes without ever opening a text editor. Traefik is a 3 / 5 — you write a static config, enable the Docker provider, define an ACME resolver, mount the Docker socket read-only, and learn how routers, services, and middlewares fit together before it clicks. That learning curve buys you power, but it is a real curve.

On resources both are light. Traefik's lone Go binary has the smaller floor at roughly 256 MB, while NPM wants a little more — around 512 MB — because it runs Node.js and Nginx together. Either fits on the smallest VPS with room to spare; the RAM gap is minor next to the difference in how you operate them.

Which should you self-host?

Pick Nginx Proxy Manager if…

• You want clean domains and automatic HTTPS from a point-and-click UI, with no config files to write.
• Your services are a mix — some in Docker, some not — and you want one place to manage every route regardless of where it runs.
• You are newer to reverse proxies and want the fastest possible path from "app on a weird port" to "app on a real domain with a valid cert."

Pick Traefik if…

• Your stack is Docker-heavy and you want proxies and TLS to configure themselves from container labels as you add services.
• You need advanced middleware — auth, rate limiting, header rewriting — and metrics baked into the proxy.
• You are comfortable trading a steeper setup for a proxy you rarely have to touch once it is running.

Running either on a VPS

Both run comfortably on a single small server, and either will put valid HTTPS in front of your apps without fuss. Traefik has a slightly lighter footprint and shines once your stack is large and container-native; NPM gets a beginner to the same clean-domains-with-TLS result far faster and stays out of the config files, which is why it takes the nod here for most self-hosters. The step-by-step setups are linked below, and any of the VPS options here has plenty of room for the proxy plus the apps sitting behind it.
