Pick Open Policy Agent if…
OPA suits teams that need policy decisions across services, Kubernetes, CI/CD pipelines or API gateways, and can work with Rego and its evaluation interfaces. Those exposing its API should account for the fact that authentication and authorization are off by default.
Pick Terraform if…
Terraform Community Edition suits practitioners who want a downloadable command-line tool for infrastructure provisioning. HCP Terraform's free features are described as suitable for small teams, while larger organizations may need paid collaboration and governance features.
