Drag the nodes. The workflow
builds itself.
Pick workflow:
Input socket
Output socket
Drag a node by its header. Wires re-route automatically.
What you're seeing. A ComfyUI workflow is just a directed graph of nodes. Each node has typed input sockets (left) and output sockets (right). Wires connect output to input — data flows from left to right through the graph. A node only runs when all its inputs are available. The JSON serialization below the graph is the workflow's source of truth — it can be version-controlled, shared, or POSTed to the ComfyUI API for headless execution. What this demo simplifies: real ComfyUI has hundreds of node types, custom node packs, complex conditioning routing, and live preview hooks. The pattern shown here is the canonical 6-node txt2img skeleton that every workflow grows from.
