Langflow

Visual, low-code builder for creating LLM workflows and AI applications with a drag-and-drop graph interface. Each node represents a component—an LLM call, a retriever, a prompt template, a tool—and you wire them together to build complex chains and agents without writing pipeline code. Open-source and self-hostable; integrates with LangChain under the hood. Free and open-source. Best for developers, data scientists, and AI engineers who want to prototype and iterate on LLM pipelines visually before committing to code.
