Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Cosmos
- No Git-based or CI/CD deployment pipeline for custom code
- App marketplace is smaller and less mature than CasaOS or Umbrel
- Multi-server and horizontal scaling are not supported
- Documentation and community support are limited compared to more established platforms
Traefik
- Ingress/routing layer only; does not provide git-based deployments, build systems, or app management
- Configuration via labels and providers has a steep learning curve compared to Heroku's zero-config UX
- No built-in secrets management or environment variable injection for deployed apps
- Enterprise features (clustering, advanced WAF, SSO) require the commercial Traefik Enterprise edition
Bottom line
Choose Cosmos if you want the lower-effort setup; choose Traefik for the larger community and ecosystem. Traefik has seen more recent development. Open each guide below for deploy steps and the full feature gap.
