Agents that ship media, not just messages.
Langflow is a low-code builder for LLM apps — chatbots, RAG, agents — rooted in Python and LangChain. NodeTool covers that same ground and adds what Langflow leaves to external APIs: native image, video, and music generation with editing tools on the same canvas. Open source, BYOK at provider prices, local models included.

The pipeline and the picture, on one canvas
If your project ends at a chatbot or a RAG pipeline, Langflow is a solid choice — visual flows, Python extensibility, a mature LangChain ecosystem. But the moment an agent needs to produce something you can look at or listen to — a storyboard, a product video, a soundtrack — Langflow hands you an API key form and a blank HTTP node. NodeTool keeps going: generation nodes for image, video, and music from every major provider sit on the same canvas as your agents and retrieval, with masks, inpaint, relight, upscale, and layers built in. You bring your own keys and pay provider list prices — no credits, no markup — and run local models via Ollama, MLX, and llama.cpp on the desktop.
Build agents that make things.
