ComfyUI-MouseCoords

Display real-time mouse coordinates in graph space for ComfyUI workflows.

Features

• Real-time display of mouse position in graph coordinates
• Always visible in top-right corner of canvas
• No configuration needed

Installation

Via ComfyUI Manager (Recommended)

1. Open ComfyUI Manager
2. Search for "MouseCoords"
3. Click Install
4. Restart ComfyUI

Manual Installation

1. Navigate to your ComfyUI custom nodes directory:

   cd ComfyUI/custom_nodes/

2. Clone this repository:

   git clone https://github.com/Malkalypse/ComfyUI-MouseCoords.git

3. Restart ComfyUI

Usage

Once installed, the mouse coordinates will automatically appear in the top-right corner of your canvas. The coordinates are displayed in graph space (not screen space), which is useful for:

• Positioning nodes precisely
• Debugging node layouts
• Measuring distances between elements
• Creating extensions that need coordinate information

How It Works

This extension is intentionally minimal:

• Pure JavaScript, no Python dependencies
• Uses ComfyUI's built-in coordinate conversion
• Automatically loads a small CSS file for styling
• No API calls or backend processing
