I will say Langchain is more for orchestrating LLM, so it’s not really about agents or agents coordination like KaibanJS. (We do use Langchain behind the scenes for some of that). LangGraph while focused on agents, is super low level. you can do complex stuff, but the learning curve is bit high. I also think it could take better advantage of the JS ecosystem (like state management and deeper React/Node.js integration). But this is my personal opinion.
