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

• 🔀 Auto-detour — links route around nodes instead of passing through them
• 🖱️ Smooth dragging — anti-flicker stickiness keeps shapes stable while you drag
• ✨ Flow animation — dots / pills / arrows / ovals / dashes on hover or selection
• 🎯 Highlight & dim — selected node's links brighten, others fade to focus
• 🎛️ Floating bar — quick toggles for routing, link style, flow mode, and settings
• ⚙️ Full settings panel — everything adjustable with live preview
• 🚀 Zero performance cost — pure browser canvas, no GPU/VRAM impact

Installation

ComfyUI Manager (recommended)

Search LinkRouter and install.
