StackMatch Editorial verdicts

Bylined · No vendor influence
LangChainEVALUATE
Necessary, complicated, unavoidable

LangChain is the most complete LLM orchestration framework and the most criticized for good reason. Use LangGraph for the actual agent loops; treat the broader LangChain surface area cautiously.

Choose LangChain if...

Engineers building production RAG systems, multi-step AI agents, or complex LLM pipelines.

Avoid LangChain if...

Simple single-API-call applications — direct API calls are simpler and faster.

Choose Dust if...

European enterprises wanting Glean-style work assistance with more agent customization; product teams shipping internal AI agents to business users.

Avoid Dust if...

M365 shops (Copilot is bundled), or teams needing the deepest possible search index (Glean still wins on raw retrieval scope).
