Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Caddy
- Not a full PaaS; no git push deploy, build pipelines, or app lifecycle management
- No built-in CI/CD integration; needs to be combined with other tools for deployments
- Dashboard and metrics require third-party tools (Prometheus, Grafana) — none built-in
- No managed database provisioning or environment variable secrets management
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
Both are a similar lift to self-host; choose Caddy for the larger community and ecosystem. Open each guide below for deploy steps and the full feature gap.
