ComfyUI WebUI Generator Node

A ComfyUI custom node that generates a shareable HTML UI from a ComfyUI API workflow JSON.

Install

Clone into: ComfyUI/custom_nodes/ComfyUI-WebUI-Generator-Node

Restart ComfyUI.

Node

Workflow → HTML (Generator)

Input:

• api_workflow_json_or_path: paste API workflow JSON OR give a path to a .json
• output_name: used to name the generated file
• open_in_browser: auto-open the generated URL (best effort)
• comfy_base_url (optional): if your ComfyUI isn't on localhost

Output:

• html_url: served by ComfyUI under /extensions/.../generated/...
• html_file_path: local path

IMPORTANT: Use API workflow JSON

In ComfyUI: export the workflow as API workflow JSON (not the normal workflow JSON).
