ComfyUI Seed Tracker

A custom node extension for ComfyUI that tracks and logs random seeds used throughout your image generation workflows.

Features

• Track individual seeds from specific nodes
• Global seed tracking mode to monitor seeds in a workflow
• Export seed logs in different formats (JSON, CSV, TXT)
• Organize seeds by session ID for easy reference
• Add custom notes to tracked seeds

Installation

Using ComfyUI Manager

1. Open ComfyUI
2. Open ComfyUI Manager
3. Search for "Seed Tracker"
4. Click Install

Manual Installation

1. Navigate to your ComfyUI custom_nodes directory:

   cd ComfyUI/custom_nodes/
   

2. Clone this repository:

   git clone https://github.com/angelcookies/comfyui-seed-tracker.git
   

   Alternatively, download and extract the ZIP file to your custom_nodes directory.

3. Restart ComfyUI

Usage

After installation, you'll find the following nodes in the "utils/seed_tracking" category:

Seed Tracker Node

Connect this node to track seeds from individual nodes.

Inputs:

• seed: The seed value to track
• node_id: A unique identifier for the node (helps with organization)
• notes: Optional notes to add context to the tracked seed

Outputs:

• seed: The same seed passed through (for convenience in workflows)
• log_path: Path to the JSON log file

Global Seed Tracker Node

A central node that collects and manages seeds from all connected Seed Tracker nodes.

Inputs:

• enabled: Toggle tracking on/off
• seed_data: Connection from Seed Tracker nodes (internal data type)
• session_name: Optional custom session name
• show_debug: Show debug information including log file path

Outputs:

• None by default (works silently)
• log_path: Only shown when show_debug is enabled

Example Workflow

1. Add individual "Seed Tracker" nodes to any samplers or random number generators
2. Connect the seed_data output from each Seed Tracker to the seed_data input of a Global Seed Tracker
3. The Global Seed Tracker will collect and consolidate all seeds into a single session log
4. When you want to export your tracked seeds, use the "Seed Exporter" node

Seed Exporter Node

Export tracked seeds in different formats.

Inputs:

• session_id: The session ID to export (leave empty for all sessions)
• format: Output format (json, csv, txt)

Outputs:

• export_path: Path to the exported file

Log Files

All seed logs are stored in your ComfyUI output directory under a seed_logs folder. Each session creates a unique log file with timestamp-based naming.

Example Workflow

1. Add a "Global Seed Tracker" node at the beginning of your workflow
2. Connect "Seed Tracker" nodes to any KSampler or other nodes where you want to track specific seeds
3. When you want to reference seeds later, use the "Seed Exporter" node to export them in your preferred format

Advanced Integration

For advanced users who want to automatically track all seeds without manually connecting nodes, you can modify the ComfyUI server code to hook into the execution system. This requires deeper integration with the ComfyUI API and is beyond the scope of this basic extension.

Future Features

• Automatic seed detection without manual node connections
• Web UI for browsing and searching captured seeds
• Integration with prompt history
• Thumbnail generation for associated images
