Karaka or LangGraph + LangSmith?

Choose LangGraph and LangSmith for mature orchestration, deployment, tracing, and evaluations. Choose Karaka when an existing Node backend needs to run DSH separately without building the chat API, ownership model, streaming transport, and MCP tool host itself.

Choose Karaka when

Your product already has a Node backend and you want to use DSH.
You want to expose selected callbacks without moving business logic.
Application, tenant, and user ownership should be part of every chat.
You want plugins to replace the model, loop, persistence, tools, skills, filesystem, or policy.

Choose LangGraph + LangSmith when

You need branching, parallel work, or human review.
You want managed deployment and mature persistence.
Tracing, evaluations, and prompt tooling are requirements.
A broad integration ecosystem matters more than a narrow Node path.

What differs

Area	Karaka	LangGraph + LangSmith
Primary value	Application integration layer for running DSH beside a Node backend.	Build, deploy, trace, and evaluate agent workflows.
Backend tools	Register selected Node callbacks behind authenticated MCP.	Use tools and integrations from the LangChain ecosystem.
Orchestration	Plugins can replace the model, loop, persistence, tools, skills, filesystem, and policy.	Graphs, functional APIs, branching, parallelism, and human review.
Operations	Self-hosted. You own TLS, scaling, backups, and monitoring.	Self-hosted or managed deployment with production tooling.
Maturity	Alpha developer preview.	Established framework, platform, and integration ecosystem.

Use neither when

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