ComfyUI Save Prompt and Output

Sponsor

This custom node and hook for ComfyUI automatically saves all intermediate outputs (images and metadata) for every executed node in your workflow.

Features

  • Automatic Hook: No need to place special nodes. Just running your workflow captures everything.
  • Workflow Logging: Saves the full workflow and parameters used for generation.
  • Intermediate Output: Captures outputs from executed nodes, including images and non-image data (serialized).
  • Organized Storage: Creates a unique folder for each execution (Queue) based on the Prompt ID.
    • Path: ComfyUI/output/hooked_outputs/<prompt_id>/

Installation

  1. Clone this repository into your ComfyUI/custom_nodes/ directory:

    cd ComfyUI/custom_nodes/
git clone [email protected]:t22m003/ComfyUI_SavePromptAndOutput.git

  2. Restart ComfyUI.

Usage

Just run your workflows as usual. Check the ComfyUI/output/hooked_outputs/ directory for results.

Configuration

Currently, the save path is hardcoded to ComfyUI/output/hooked_outputs. You can modify hooks.py if you need to change the location.
