Cable Management for ComfyUI

ComfyUI has spaghetti issues. This frontend extension offers daisy-chaining, PCB routing, ribbon cables, and proper right-to-left wrapping support.

"WTF IS THAT?????" -- "a bunch of reroutes in a trenchcoat"

Built entirely from core ComfyUI primitives -- remove the extension and every workflow made with it still loads and runs.

Early release. Expect bugs; criticism and praise equally welcome. Requires a recent ComfyUI (tested on 0.28-0.30, frontend 1.47-1.48) with Nodes 2.0.

Install Extension

• ComfyUI Manager: search Cable Management, install, restart ComfyUI.
• Manual: git clone https://github.com/vtokic/comfyui-cable-management into ComfyUI/custom_nodes/, restart ComfyUI.

Cable Management Settings

PCB Routing and Ribbons

• Settings > Lite Graph > Graph > Link Render Mode "PCB"

Input/Widget Passthroughs and drawers

• Settings > Comfy > Nodes 2.0 > Modern Node Design (Nodes 2.0) ON
• Settings > Lite Graph > Graph > Cable Management ON (Modifies nodes' UI, enables passthrough and daisy-chaining)

Recommended ComfyUI Settings

• Settings > Lite Graph > Link > Link midpoint markers "Arrow"
• Settings > Lite Graph > Link Release > Action on link release (No modifier) "context menu" (Makes reroutes easier to create)

Functionality

• PCB Link Render Mode -- links do their best to path around nodes and avoid each other
• Cable Management -- node pin changes:
  • connected inputs get a pass-through pin on the opposite side of the node, for daisy-chaining
  • widgets get an output pin so their value can be pulled out as a primitive
  • outputs move to the bottom-right of the node (contract shape)
  • inputs and outputs collapse into drawers, hiding unconnected optional inputs and unused outputs
• Ribbons: stack reroutes on top of each other and they bundle into one ribbon cable
