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

Terraform

HCL syntax requires learning a domain-specific language with limited GUI alternatives
State file management is complex, especially at scale with multiple workspaces
terraform import workflow is fiddly and must be done one resource at a time
No native error handling or try-catch capabilities like traditional programming languages
No automatic rollback capability - must manually delete and re-run if needed
