What is ComfyUI_show_seed?

A custom node that saves images while displaying the seed value used in generation

How to install it in ComfyDeploy?

Head over to the machine page

  1. Click on the "Create a new machine" button
  2. Select the Edit build steps
  3. Add a new step -> Custom Node
  4. Search for ComfyUI_show_seed and select it

ComfyUI Show Seed

A ComfyUI custom node that extracts and displays the seed value used in image generation, making it easier to track and reuse successful generations.

Why This Node?

  • ComfyUI randomly updates seed values after each generation
  • Default interface doesn't show seed values intuitively
  • Helps maintain seed consistency when upscaling images

Features

  • Displays seed values from KSampler nodes in real-time
  • Passes through image data unchanged
  • Simple integration with existing workflows
  • Zero configuration required - just plug and play

Installation

Option 1: Install via ComfyUI Manager (Recommended)

  1. Install ComfyUI Manager
  2. Open ComfyUI
  3. Go to Manager tab
  4. Search for "Show Seed"
  5. Click Install

Option 2: Manual Installation

cd ComfyUI/custom_nodes/
git clone https://github.com/dreamhartley/ComfyUI_show_seed.git

Usage

Connect it after your KSampler node, and the seed value will be displayed directly on the node.

Example Workflow

Example Workflow

The node works as a pass-through for image data while extracting the seed information:

  • Input image → Show Seed → Save Image node
  • Show Seed (seed_info) → Text node

Node Outputs

  • images: Original image data (connect to Save Image node)
  • seed_info: Extracted seed value (connect to Text node)
