What is LangGraph-GUI?
LangGraph-GUI is a self-hosted graphical interface for designing and executing LangGraph workflows through a visual node-edge editor built with SvelteFlow. The frontend communicates with a FastAPI backend that converts graph JSON into executable LangGraph workflows. Users can run workflows with local language models via Ollama (with NVIDIA GPU support) or configure external LLM APIs. The project supports multi-user deployments through nginx basic authentication, where each user gets an isolated workspace. Deployment options include Docker Compose (with separate frontend, backend, and Ollama containers), Kubernetes manifests, and manual installation on Windows or Linux. The software is licensed under MIT and maintained by HomunMage.
