Traefik
FreemiumThe cloud-native application proxy.
Published 27 September 2026
Scores
Popularity4/5
It's the de facto reverse proxy for the Docker/Kubernetes self-hosting community and powers routing inside Coolify and Dokploy, with a large and actively growing GitHub following, though still behind NGINX's decades-long install base.
Learning Curve3/5
Basic Docker label routing is quick to pick up, but understanding the provider model, middleware chains, and dashboard takes more upfront investment than Caddy's flat config file, especially for anyone unfamiliar with label-driven tooling.
Flexibility4/5
Native providers for Docker, Kubernetes, Swarm, Consul, and ECS plus a composable middleware system cover most container-routing scenarios, though its module ecosystem is narrower than NGINX's after two decades of third-party extensions.
Performance4/5
Built in Go with an efficient routing engine, it performs comparably to Caddy for typical self-hosted and mid-scale container workloads.
Portability5/5
MIT licensed, ships as a single binary and official Docker image, and runs identically across any VPS, Kubernetes cluster, or cloud provider with no lock-in.
About Traefik
Traefik is a reverse proxy and load balancer built specifically for containerized and orchestrated environments. Instead of maintaining a separate config file that lists every backend service, Traefik watches the Docker (or Kubernetes, Swarm, Consul, ECS) API directly and builds its routing table from labels attached to each container. Adding a new service to a Docker Compose stack is typically just a few label lines on that service — no restart or manual reconfiguration of the proxy itself is needed.
This label-driven, auto-discovery model is what distinguishes it from NGINX and Caddy, both of which require routes to be defined in a central config. It's also the reason Traefik is used internally by self-hosted PaaS platforms like Coolify and Dokploy to route traffic to whatever containers they deploy. Traefik includes automatic HTTPS via Let's Encrypt (similar to Caddy), a built-in web dashboard for visualizing the current routing table, and native integrations for health checks, circuit breakers, and middleware chains (rate limiting, auth, header manipulation).
The core Traefik Proxy is open source (MIT license) and free with no feature gating for self-hosted use. Traefik Labs, the company behind it, sells Traefik Hub — a separate commercial API management and Kubernetes ingress product built on top of the open-source proxy — but this is an add-on, not a paywall on core reverse-proxy functionality.
Key Features
- Automatic service discovery from Docker labels — no manual route config for new containers
- Automatic HTTPS via Let's Encrypt
- Built-in web dashboard showing live routing state
- Native integrations: Docker, Kubernetes Ingress, Swarm, Consul, ECS
- Middleware chains: rate limiting, basic auth, header rewriting, circuit breakers
- Zero-downtime config reloads as containers start/stop
Pros
- Docker label-based auto-discovery eliminates most manual proxy configuration work
- Purpose-built for container orchestration — first-class Kubernetes Ingress support
- Automatic HTTPS out of the box, same convenience as Caddy
- Used internally by Coolify/Dokploy, so patterns learned here transfer directly
Cons
- Steeper initial learning curve than Caddy if you're not already used to label-based config
- Dashboard and routing model add a layer of abstraction that can be harder to debug than a flat NGINX config file
- Smaller community/tutorial base than NGINX, though larger than Caddy's
- Best suited to containerized deployments — less natural fit for bare-metal, non-Docker setups

Tech Stacks with Traefik
Airflow Self-Hosted
InfrastructureThe reference scheduler for data pipelines on your own server: Airflow's official Docker Compose deployment, with a SQL metadata database (PostgreSQL by default, MySQL also supported) and Redis as the Celery worker queue.
WordPress Self-Hosted
InfrastructureThe CMS behind the open web on your own server: WordPress with its own database (MariaDB by default; MySQL equally supported) and Docker, with any plugin and any theme, and no managed-WP vendor in sight.
Langfuse Self-Hosted
InfrastructureRun Langfuse, the open-source platform for tracing and improving LLM applications, in Docker on your own server. The official bundle pairs the app with PostgreSQL, ClickHouse, Redis, and an S3-compatible blob store, so traces, evaluations, and prompt management stay entirely on infrastructure you control.
Tools Related to Traefik
Works well with Traefik(3)
Hetzner VPS instances are a common host for self-hosted Traefik deployments, pairing a low-cost VPS with Traefik's container-native routing.
Traefik is commonly placed behind Cloudflare Tunnel in Docker-based self-hosted setups — the tunnel handles secure ingress with no open ports, Traefik handles container-aware routing to the actual local services.
Traefik is commonly placed behind ngrok in Docker-based dev setups when the tunnel needs to reach more than one local service — ngrok handles the public URL, Traefik routes to the actual backend services.
Integrates with Traefik(3)
Traefik ships inside Dokploy as its reverse proxy, routing traffic and issuing certificates for the applications Dokploy deploys. A stack that uses Dokploy gets Traefik with it.
Traefik is the reverse proxy that ships inside Coolify by default, handling routing and automatic HTTPS for the containers Coolify deploys. With Coolify in the stack, Traefik is already there and is not set up separately.
Traefik's Docker provider is a first-class, officially documented feature — it watches the Docker API directly and builds its routing table from labels attached to each container, with no manual config file needed.
Alternatives to Traefik(2)
Traefik and Caddy both offer automatic HTTPS with minimal config, but Caddy uses a simpler flat Caddyfile while Traefik is purpose-built around Docker/Kubernetes label-based service discovery.
Traefik and NGINX both act as reverse proxies, but NGINX uses static config files with decades of tutorials behind it, while Traefik auto-discovers routes from container labels.
