Karaka or AWS AgentCore?

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.

What differs

AreaKarakaAWS AgentCore
Primary valueApplication integration layer for running DSH beside a Node backend.Run agents on managed AWS infrastructure.
Backend toolsRegister selected Node callbacks behind authenticated MCP.Connect MCP, OpenAPI, Lambda, Smithy, and API Gateway tools.
Data accessAdd MCP services or replace persistence and filesystem providers through plugins.Managed memory, S3, EFS, and VPC access.
OperationsYou own TLS, scaling, backups, identity, and monitoring.Managed isolation, scaling, identity, policy, and observability.
MaturityAlpha developer preview.Generally available AWS services, with some features in preview.

For new AWS users, AgentCore is the relevant comparison. AWS says Bedrock Agents Classic is closed to new customers.

Use neither when

One model call or a short deterministic tool loop solves the job. Keep it inside your backend.
