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
DietPi
- OS-level tool; no web-based deployment dashboard or CI/CD integration
- Software installs are opinionated scripts; customizing or composing services requires Linux knowledge
- No built-in container orchestration; Docker is available but not the primary deployment model
- No multi-server management; designed for single-node personal use
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.
