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

![Before vs After](screenshots/demo.jpg)

## Features

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

## Installation

### Via ComfyUI Manager

Search for **LinkRouter** in ComfyUI Manager and click **Install**.

### Manual

```bash
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**.
