Langflow vs LangChain

Langflow vs LangChain compares a no-code visual builder to the underlying code-first framework. LangFlow wraps LangChain in a graph editor: users drag nodes—LLM, Prompt, Vector Store, Tool—connect them with arrows, tweak parameters in a sidebar, and hit Run to test. It exports the graph as JSON or Python, making it ideal for product managers and data scientists who want rapid prototyping without writing code. LangChain itself is a modular SDK—loaders, embeddings, chains, agents, memory—best suited for developers who need version control, fine-grained logic, and CI/CD pipelines. LangFlow accelerates ideation, demos, and education; LangChain excels at scalable, unit-tested production apps. Teams often pair them: design the workflow in LangFlow, then refine and deploy with LangChain code.
