LangChain
PickMIT framework for agents and LLM apps: compose models, tools and retrieval. Not a model brand, and not a synonym for LangGraph.
Why it's listed
For developers who need to flexibly assemble LLM apps without being locked into a specific model or vendor, LangChain is a solid choice. You can prototype quickly by composing different models, retrieval, and tool chains. Note that it's not the same as LangGraph — LangChain is more of a general composition layer, making it a lower-barrier entry point if you're new to agent development.
