Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
CasaOS
- No built-in CI/CD pipelines or Git-based deploy workflows like Heroku/Render
- App store limited to curated Docker images; no support for custom buildpacks
- No auto-scaling, horizontal scaling, or load balancing across multiple hosts
- SSL/TLS certificate management is basic compared to managed PaaS offerings
Pomerium
- No application deployment or hosting capabilities; purely an access proxy layer
- Policy configuration via YAML can be complex; lacks a full-featured web UI in the open-source edition
- Device posture checking and some enterprise features require the commercial Pomerium Zero/Enterprise tier
- Setup complexity is significantly higher than simpler tools like Nginx Proxy Manager for basic use cases
Bottom line
Choose CasaOS if you want the lower-effort setup; choose CasaOS for the larger community and ecosystem. Pomerium has seen more recent development. Open each guide below for deploy steps and the full feature gap.
