ComfyUI-LinkRouter

I'm new to all this — first plugin, first GitHub repo, learning as I go. If you find bugs, have ideas, or just want to help a beginner out, I'd be incredibly grateful. Bug reports, PRs, suggestions, or just buying me a coffee ☕ — every bit of support honestly makes my day. Thank you! 🙏

Object-avoiding orthogonal link routing for ComfyUI. Links automatically detour around nodes with smooth right-angle paths — no more spaghetti lines.

Features

Links automatically route around nodes instead of through them. Animated flow markers on hover or selection. Floating bar for quick toggles.

Installation

cd ComfyUI/custom_nodes/
git clone https://github.com/90-RED/ComfyUI-LinkRouter

Then reload ComfyUI with Ctrl+R.

Usage

LinkRouter is enabled by default. A floating bar appears on the right:

| 🔀 | Toggle routing | | 🌊📐➖ | Cycle official link styles | | ✨➤◾ | Cycle flow markers (animated/static/none) |

All visual parameters are in Settings → LinkRouter.
