Traefik vs Cosmos Cloud: Proxy Approaches
Quick Verdict
Traefik is the better dedicated reverse proxy with Docker-native service discovery, extensive middleware, and a proven track record. Cosmos Cloud is an all-in-one platform where the proxy is one feature among many (container management, app store, VPN, security). Choose Traefik if proxy quality matters most; choose Cosmos Cloud if you want one tool for everything.
Overview
Traefik is a cloud-native reverse proxy that automatically discovers Docker containers via labels and handles SSL certificates, routing, and middleware without manual config changes. Current version: v3.6.8.
Cosmos Cloud is a self-hosting platform combining Docker management, reverse proxy, app marketplace, VPN (Constellation), user auth, and DDoS protection in a single package. Current version: v0.20.2.
Feature Comparison
| Feature | Traefik v3.6 | Cosmos Cloud v0.20 |
|---|---|---|
| Docker auto-discovery | Yes (labels) | Container listing |
| Automatic SSL | Built-in ACME | Built-in |
| Configuration | Docker labels + YAML | Web UI |
| Container management | No | Yes |
| App marketplace | No | Yes |
| User management | No | Yes (multi-user, 2FA) |
| VPN integration | No | Yes (Constellation) |
| DDoS protection | No | Yes (Smart Shield) |
| Middleware chain | Extensive (15+) | Limited |
| ForwardAuth (SSO) | Yes | Built-in identity provider |
| Dashboard | Read-only | Full management UI |
| Load balancing | Yes (multiple algorithms) | Basic |
| TCP/UDP proxying | Yes | Yes |
| HTTP/3 | Experimental | No |
| RAM usage | ~50-80 MB | ~150-200 MB |
When to Choose Each
Choose Traefik If…
- You want Docker-native auto-discovery (add labels, done)
- You need advanced middleware (rate limiting, circuit breaking, retry)
- You need ForwardAuth with Authelia or Authentik for SSO
- You already have a container management tool (Portainer, Dockge)
- You want a proven, battle-tested proxy used by enterprises
- You want config-as-code via Docker labels
Choose Cosmos Cloud If…
- You want one platform for proxy + management + security
- You’re setting up a new self-hosting environment from scratch
- You want built-in authentication without external identity providers
- You want an app marketplace for one-click deployments
- You don’t need advanced proxy middleware
Final Verdict
Traefik for proxy quality, Cosmos Cloud for platform simplicity. Traefik is the better reverse proxy — its auto-discovery, middleware chain, and ForwardAuth integration are features Cosmos Cloud’s built-in proxy can’t match.
But Cosmos Cloud’s value proposition isn’t being the best proxy — it’s being a good-enough proxy bundled with container management, security, and an app store. If that all-in-one approach appeals to you and you don’t need Traefik’s advanced features, Cosmos Cloud simplifies your stack.
The modular approach (Traefik + Portainer + Authelia) gives you the best tool for each job but requires configuring three separate systems. Cosmos Cloud gives you one thing to configure.
Frequently Asked Questions
Can I add Traefik labels to Cosmos Cloud-managed containers?
Not in a meaningful way. Cosmos Cloud manages its own proxy routing through its UI. To use Traefik, you’d need to disable Cosmos Cloud’s built-in proxy, which undermines its integrated approach.
Does Cosmos Cloud support ForwardAuth like Traefik?
Cosmos Cloud has its own built-in identity provider instead of relying on ForwardAuth. It handles authentication internally rather than delegating to external providers like Authelia or Authentik.
Which is easier for beginners?
Cosmos Cloud. It provides a guided setup, app store, and visual management. Traefik requires understanding Docker labels, entrypoints, and certificate resolvers — a steeper learning curve for beginners.
