Cedar

Cedar is worth adding because it represents a foundational authorization design choice rather than just another product SKU. The official docs position Cedar as a language for writing authorization policies and making authorization decisions based on them, with strong emphasis on separating business logic from authorization logic. That makes it especially important for teams that want policy to become an explicit, auditable part of system design rather than a scattering of application-side conditionals.

Its pricing story is straightforward because Cedar is a language and open-source engine, not a SaaS product. The official docs and repository focus on the language, policy model, and integrations. There is no public subscription price for Cedar itself. The standard language and open-source implementation are free to adopt, while spend only appears if a team chooses a managed service that uses Cedar, such as Amazon Verified Permissions.
