langflow

Why we included this project

Langflow is a visual builder for AI agents and multi-step workflows: you assemble flows on a drag-and-drop canvas instead of writing orchestration code. Each node corresponds to a real component, and when the UI is not enough, you can open the Python source of any component and adjust it directly. Once a flow works, you can expose it as a REST API or an MCP server, turning the same design into a callable tool inside a larger application. It comes with connectors for the major LLM providers and vector stores, and the interactive playground lets you step through a flow and debug it before you deploy. Teams that would rather assemble agents visually than hand-write orchestration logic will find it a practical place to start.
