The short version

Each has a real cost: authentik smaller project than Keycloak, with a correspondingly smaller community and fewer integration guides; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
They diverge on capability: authentik covers Configurable flows, Weka covers Classification.

Where each one falls short

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

authentik

Smaller project than Keycloak, with a correspondingly smaller community and fewer integration guides
The flow model is flexible but conceptually unfamiliar, and simple setups can feel over-abstracted
Enterprise support and some governance features sit behind the paid tier
Self-hosted identity is still yours to secure, patch and keep available

Weka

The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture
