Choose AgentCore for managed AWS infrastructure, identity, memory, policy, scaling, and observability. Choose Karaka when an existing Node backend needs a self-hosted bridge to DSH while preserving DSH's replaceable plugin runtime.
Choose Karaka when
You want to use DSH outside the AWS AgentCore control plane.
Your Node backend should keep its existing business functions.
Application, tenant, and user ownership should be explicit.
You need plugins to replace runtime parts and can operate alpha software.
Choose AWS AgentCore when
You want managed isolation, autoscaling, and deployment.
IAM, OAuth, memory, policy, and evaluations are requirements.
Agents need S3, EFS, or private VPC services.
AWS operations matter more than replacing runtime internals.
