Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
1Panel
- More of a server/hosting control panel than a git-push PaaS; no native buildpack or git-deploy pipeline.
- No horizontal autoscaling or clustering across nodes.
- Documentation and community are strongest in Chinese; English resources lag.
- No managed cloud option or edge/CDN.
Cosmos
- No Git-based or CI/CD deployment pipeline for custom code
- App marketplace is smaller and less mature than CasaOS or Umbrel
- Multi-server and horizontal scaling are not supported
- Documentation and community support are limited compared to more established platforms
Bottom line
Both are a similar lift to self-host; choose 1Panel for the larger community and ecosystem. 1Panel has seen more recent development. Open each guide below for deploy steps and the full feature gap.
