The subgraph feature requires ComfyUI frontend version 1.24.3 or later. If you don’t see this feature, please refer to: How to Update ComfyUI
  • Images in this document are made with nightly version frontend, please refer to the actual interface
  • Some features like converting subgraph back to nodes will be supported in the future
A subgraph is a powerful ComfyUI feature that lets you package complex workflows into a single reusable subgraph node, making them easier to manage and share. Subgraph Think of a subgraph as a “folder” for your workflow – you can group related nodes together and use the entire collection as one unified subgraph node. Use subgraphs to:
  • Simplify complex workflows
  • Reuse common node combinations
  • Build more efficient workflows with modular components

​
Creating a Subgraph

1

Select nodes

Select the nodes you want to group in ComfyUI
2

Click the subgraph icon

Subgraph icon Find the subgraph icon in the toolbar
3

Subgraph created

Workflow using subgraph ComfyUI automatically creates a subgraph based on your selected nodes’ inputs and outputs
4

Customize your subgraph

Refer to Editing Subgraphs, you can edit and organize the subgraph to create a fully functional node Workflow using subgraph

Working with Subgraphs

​
Basic Operations

Subgraphs work just like regular nodes. You can:
  • Change colors and names
  • Use bypass to disable
  • Apply all standard node operations

​
Editing Subgraphs

To enter edit mode:
  • Double-click the empty area inside the subgraph (not on widgets), or
  • Click the subgraph edit button
Subgraph editing mode In edit mode you’ll see:
  1. Navigation bar: Exit the current subgraph and return to the parent level
  2. Input slots: Internal node inputs exposed to the outside
    • Connect outputs to slots like normal nodes
    • Right-click connection points to rename/delete exposed slots
  3. Output slots: Outputs exposed to the outside (same functionality as input slots)
Subgraph slots Working with slots:
  1. Default slot (labeled 1): Use this to add new input/output connections
  2. Right-click existing slots to rename, delete, or disconnect from original nodes
Note: Slot connections follow standard data type validation rules

​
Nested Subgraphs

Create even more complex workflows by nesting subgraphs within subgraphs. Nested subgraph The navigation bar shows your current level and lets you easily move between nested subgraphs. Nested subgraph navigation
