Langflow
A low-code visual builder for agentic and RAG apps that exports runnable Python.

Best for
Developers who want to see and rearrange an agent graph without writing glue code first.
Why it deserves attention
Langflow gives you a canvas of models, tools, memory, and vector stores, wires them into an agent or RAG flow, and lets you test it in the same window. Flows can be exported as JSON or Python and served through the built-in API, and MCP support connects external tools. It is MIT-licensed with 156,000 GitHub stars and ships frequent releases. Complex production systems still need engineering outside the canvas, and the visual graph can get messy at scale.
