What it does
Langflow is a visual builder for AI agents and workflows: you drag components onto a canvas, test them in a chat panel, and then call the flow as an API. It is written in Python and you can add your own components.
Good for: Prototyping an agent or RAG flow visually, then using it from your own app.
