Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
aaPanel
- Custom (non-OSI) license rather than a standard permissive/copyleft license.
- Traditional hosting panel model; no git-push or buildpack-based deploy pipeline.
- No clustering, autoscaling, or managed edge network.
- Some advanced features are gated behind a paid/pro tier.
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
Bottom line
Choose aaPanel 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.
