NodeTool

NodeTool is an open-source, local-first visual workflow builder that lets you connect drag-and-drop nodes to design and run AI pipelines—from LLMs and multimodal generators (images, audio, video) to RAG/vector search and autonomous agents—using local models or cloud APIs; it provides streaming execution and intermediate outputs for transparent debugging. Users pick NodeTool to rapidly prototype and deploy complex AI workflows (media generation, document indexing, agent automation) without coding while keeping data private, avoiding vendor lock-in, and mixing models from Hugging Face, llama.cpp, OpenAI, Replicate, etc.
