ComfyUI-SendToDiscord

ComfyUI-SendToDiscord is a custom node for ComfyUI that simplifies sending preview images to Discord via webhooks. It supports both single-image uploads and batch mode with intelligent fallback, automatic compression, and workflow preservation, making it an efficient and robust tool for sharing your generated images directly with your Discord server.

• Workflow included in the image

Features

• Smart Image Delivery: Send individual or batches of images with intelligent fallback (individual sending if batch fails)
• Automatic Compression: WebP compression with configurable quality to optimize file sizes
• Workflow Preservation: Automatically preserves ComfyUI workflow JSON when compressing images
• Metadata Support: Includes prompts and additional PNG information in saved images
• Advanced Configuration: Extensive configuration options for compression, fallback, and file size limits
• Visual Status Indicators: Real-time progress indicators with emoji feedback
• Robust Error Handling: Graceful handling of network issues and Discord API limits
• Output Node Compatibility: Functions as both preview and output node for flexible workflow integration

Requirements

• Python 3.10+
• Pillow, requests, and numpy libraries (automatically installed via requirements.txt).

Installation

• Find it at ComfyUI Registry
• Or using comfy-cli:

comfy node registry-install comfyui-sendtodiscord

Manual Install

1. Clone the repository into your ComfyUI custom nodes directory:

   git clone https://github.com/gmorks/ComfyUI-SendToDiscord.git
   

2. Install dependencies:

   cd ComfyUI-SendToDiscord
   pip install -r requirements.txt
   

3. Configure the config.ini file:
   • Locate the config.ini.template file in the root directory.
   • Copy it and rename it to config.ini:

     cp config.ini.template config.ini
     

   • Open the config.ini file and replace the placeholder with your Discord webhook URL:

     ; Configuration file for ComfyUI-SendToDiscord
     ; Replace 'your-webhook-url-here' with your Discord webhook URL.
     ; You can get a webhook URL by going to your Discord server settings, then Integrations, then Webhooks, then New Webhook.
     
     [Discord]
     webhook_url = your-webhook-url-here
     

Dependencies

This node has been tested with the following Python packages:

• Pillow>=11.0.0 (updated for better WebP support and performance)
• requests>=2.32.0 (updated for security improvements)
• numpy>=1.26.0 (updated for compatibility)

If you encounter issues, please ensure these versions or higher are installed, or consult the official ComfyUI documentation for compatible dependencies.

Usage

1. Open ComfyUI.
2. Add the "Preview Image (with Discord option)" node to your workflow.
3. Configure the node parameters:
   • Send to Discord: Enable or disable image uploads to Discord.
   • Batch Mode: Enable to accumulate images and send them in a single batch.
   • Passthrough Image (optional): Input for passing images through to other nodes.
4. Generate your images, and they will be uploaded automatically to the specified Discord channel.

Configuration

Node Parameters

• images: The list of images to process.
• send_to_discord: Enable or disable sending images to Discord (enable/disable).
• batch_mode: Accumulate images and send them as a batch (enable/disable).
• passthrough_image (optional): Input for chaining with other nodes.

Advanced Configuration (config.ini)

The node supports extensive configuration options in your config.ini file:

[Discord]
webhook_url = your-webhook-url-here

[Fallback]
# Enable automatic fallback (individual sending if batch fails)
enable_fallback = true

# Enable automatic image compression
enable_compression = true

# Compression quality (0-100, higher = better quality)
compression_quality = 80

# Maximum file size before compression (MB)
max_file_size_mb = 8

Key Features

• Intelligent Fallback: If batch sending fails, automatically attempts individual sending
• WebP Compression: Automatically compresses large images while preserving quality
• Workflow Preservation: When images are compressed, the original ComfyUI workflow JSON is automatically sent alongside
• Visual Feedback: Console messages with emoji indicators show upload progress and status
• Flexible Integration: Works as both a preview node and output node for maximum workflow compatibility

Example Workflow

You can add this node after your image generation process to preview and share your results directly.
