Lang-Agent is an AI intelligent body configuration platform developed based on LangGraph technology stack, and its core value lies in the rapid construction of complex workflows through drag-and-drop visualization interface. The platform adopts the design concept similar to ComfyUI, which is different from the fully encapsulated platforms such as Dify or Coze, and allows developers to flexibly expand the functional nodes according to business needs. The key technological breakthrough lies in the innovative "state variable" mechanism, which breaks the restriction of data transfer between nodes in traditional workflow, realizes global variable sharing and conditional control across nodes, and supports the construction of loops, branches and other complex logic.
The platform adopts a modern front-end and back-end separation architecture, with the back-end based on FastAPI framework and the front-end using ReactFlow and HeroUI to build a responsive interface. Through componentized design, Lang-Agent not only ensures that the basic functions are ready to use out of the box, but also ensures that the system has good scalability, so that developers can easily add new functional nodes to adapt to specific business scenarios.
