What is the difference between clean architecture and onion architecture?

Clean Architecture push us to separate stable business rules (higher-level abstractions) from volatile technical details (lower-level details), defining clear boundaries.

Clean Architecture It builds on the concepts of Onion Architecture but with somewhat different details of the layers . Instead of “Domain Model”, it refers to the core as “Entities”, but still representing enterprise-wide business rules.

Business rules will probably change less often than the UI designs or something in the database or the network storage . We will communicate with this layer via some provided interfaces. It does not use any concrete model or UI implementation. These are details, and remember—details change.
