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

Consul

Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead
