Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Keycloak
- Requires self-hosted deployment and operational expertise to install, configure and maintain
- No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
- Clustering and high-availability configurations require additional operational knowledge
- Community support only; commercial support requires third-party vendors or distributions
MkDocs
- No built-in versioning, which Docusaurus provides and documentation teams eventually need
- Extending past the theme means writing Python plugins
- Markdown only, so embedding interactive components is not the model
