When LangGraph is not a good fit
LangGraph is an MIT-licensed orchestration framework for building, managing and deploying long-running, stateful agents. It is made by LangChain Inc, the company behind LangChain, and provides durable execution, human-in-the-loop controls and memory. The framework is free; deployment is priced through LangSmith, whose Plus plan costs $39 per seat a month.
It is a weaker choice for:
- Quick prototypes where a higher-level framework needs less code
- Fixed monthly costs for hosted deployment: usage is metered in LSUs
- Teams that do not want to learn graph and state concepts first
