Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Authelia

Depends on a reverse proxy: it is not a standalone identity provider
Configuration is YAML-first with no administrative interface, so changes mean editing files
Not a full IAM: user management, provisioning and federation are limited compared with Keycloak
Scales poorly as an organisation-wide identity solution, which is not its target

Haystack

Requires Python programming knowledge for advanced customization
Steeper learning curve compared to no-code platforms
Community support only on free tier may limit enterprise adoption
Ongoing maintenance dependency for open-source framework
