LangChain

I have tried many no code tools such as Flowise, Dify and n8n. However, under the hood, they all base on LangChain. LangChain is like a compatible layer for all kinds of LLMs, it provides a hub of different prompt templates, vector database drivers, and workflow system called LangGraph, an online log service called LangSmith.

Sadly, all the no code tools cannot export their workflow to langChain. And writing a langGraph is not intuitive. There is an editor, langGraph studio, which is MacOS only and still in beta.

The tutorials in langGraph are cutting edge, there is a sql prompt, that can make SQL queries, which to me is some kind of risky. It is quite dangerous to let LLMs to control the database.
