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

Semgrep

Free tier caps out at 10 contributors and 10 repositories.
Secrets scanning is priced as a separate module ($15/contributor) from Code and Supply Chain.
Self-managed repositories and custom CI/CD require the Enterprise tier.
AI credits are limited per tier and additional usage requires upgrading.
