Langflow
langflow.org
Visual drag-and-drop builder for creating AI pipelines — connect LLMs, vector stores, agents, and tools without writing LangChain boilerplate.
Why it is useful
Langflow makes LangChain's powerful abstractions accessible through a graphical interface. You can prototype a multi-step agent, RAG pipeline, or tool-using chatbot visually, then export it as Python code when you're ready to productionize. The component library grows with every release.
