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
Dokku
- Primarily single-server; no built-in horizontal scaling or clustering like cloud PaaS.
- CLI-first with no official web UI (community UIs exist but are unofficial).
- No managed CDN/edge, autoscaling, or integrated team management.
- Initial setup and plugin configuration require comfort with the Linux command line.
Bottom line
Choose Caddy if you want the lower-effort setup; choose Caddy for the larger community and ecosystem. Caddy has seen more recent development. Open each guide below for deploy steps and the full feature gap.
