langflow-ai/langflow
A visual editor for AI workflows: drag components onto a canvas, wire them together, test step by step, then publish the flow as an HTTP API or an MCP server. Every component can still be edited in Python.
RiskyKey files read, not run
The README says Langflow collects anonymous usage data by default; you have to set DO_NOT_TRACK=true to stop it.
How we know
We read the README and key files, not every source file, and did not run it, so the most we can say is Idea adapted or Risky.
Good for
People who want to build RAG or agent flows by dragging boxes, and still reach into code when they need to.
Not for
Teams wanting a small code-only library. It is a full Python service to run, and dev builds keep auto-login on, so check that before exposing it.
