ComfyUI reports node IDs when it encounters errors, but there's no built-in tool to find those node IDs quickly. That's now solved with this custom node/tool.

Ever had this in the console?

Here's the solution!

Features

🔍 Multiple Search Modes

The extension now features a tabbed interface with four search modes:

📍 By ID

Enter any node ID to instantly locate and highlight it
Auto-centers the canvas on the found node
Perfect for debugging when error messages reference specific node IDs

📛 By Title

Search nodes by their title, color, cnr_id, aux_id, or name
Finds nodes based on your custom naming and organization
Real-time search as you type (searches after 2+ characters)

📦 By Pack (Experimental)

Search for all nodes from a specific pack/extension
Examples: "rgthree", "WAS", "efficiency", "controlnet"
Includes smart alias matching (e.g., "easy" finds "EasyUse")

🔎 By Type (Experimental)

Search by node type/class name
Examples: "KSampler", "CLIPTextEncode", "LoadImage"
Useful for finding all instances of a specific node type

🎯 Inspector Mode

Available in "By ID" tab only
Click any node to see its ID
Automatically fills the search field with clicked node ID
Great for exploring and mapping your workflow

📜 Tab-Specific Search History

Each search mode maintains its own history
Stores up to 10 recent searches per tab
Click any history item to quickly re-search
History persists between sessions

⌨️ Keyboard Shortcuts

Ctrl+Shift+F: Toggle search panel
Escape: Close search panel
Enter: Execute search (in ID mode)

🎨 Visual Highlighting

Found nodes are highlighted in orange
Multiple results shown in an interactive list
Click any result to center and highlight that node
Original colors are preserved and restored
Clear highlighting with one click

⚙️ Experimental Features Toggle

Enable/disable experimental search modes (Pack & Type)
Setting persists between sessions
Warning indicators on experimental tabs

Installation

Download or clone this repository to your ComfyUI/custom_nodes/ directory:

cd ComfyUI/custom_nodes/
git clone https://github.com/alFrame/ComfyUI-AF-Find-Node-by-ID.git

Restart ComfyUI
The extension will automatically load - look for the console message:
```
🔍 AF - Find Node by ID extension loaded!
```

Usage

Opening the Search Panel

Press Ctrl+Shift+F anywhere in ComfyUI to open the search panel
The panel remembers your last active tab

Finding Nodes by ID

Make sure you're on the "🔍 By ID" tab
Enter a node ID in the search field (e.g., 42)
Click "Find" or press Enter
The node will be highlighted and centered on screen

Finding Nodes by Title

Switch to the "📛 By Title" tab
Start typing any part of a node's title, color, or identifier
Results appear automatically as you type
Click any result to jump to that node

Finding Nodes by Pack (Experimental)

Enable experimental features at the bottom of the panel
Switch to the "📦 By Pack" tab
Enter a pack name (e.g., "rgthree", "WAS", "controlnet")
Browse results and click to navigate

Finding Nodes by Type (Experimental)

Enable experimental features at the bottom of the panel
Switch to the "🔎 By Type" tab
Enter a node type (e.g., "KSampler", "CLIP")
View all matching nodes in your workflow

Using Inspector Mode

Switch to the "🔍 By ID" tab
Click the "Inspector" button to enter inspector mode
Click any node in your workflow to see its ID
The ID will automatically appear in the search field
Click "Exit Inspector" to return to normal mode

Search History

Recent searches appear as clickable buttons below the search field
Each tab maintains its own independent history
Click any history item to quickly search for that node/term again
History is saved and persists between ComfyUI sessions

Perfect For

Debugging workflows when error messages reference node IDs
Large workflow navigation - quickly jump to specific nodes
Workflow organization - finding nodes by your custom titles
Pack exploration - locating all nodes from a specific extension
Type analysis - finding all instances of a node type
Workflow documentation - mapping node IDs for reference

Error Message Integration

When ComfyUI shows error messages like:

Error occurred when executing node 147

Simply:

Open AF - Find Node by ID (Ctrl+Shift+F)
Type 147 and press Enter
Instantly locate the problematic node!

Known Limitations

⚠️ Experimental Features Notice

The "By Pack" and "By Type" search modes are marked as experimental because:

Different node packs use varying conventions for storing metadata
Pack information may not always be consistently available
Some nodes may not be correctly identified by their pack
Results may include false positives or miss some nodes

These features work best with well-structured node packs but may produce unexpected results with others.

Not Compatible with Subgraphs

This extension does not currently support searching within subgraphs or nested workflows.

Compatibility

Works with all ComfyUI workflows
Compatible with custom nodes
No dependencies on other extensions
Pure JavaScript implementation
Tested with ComfyUI v0.0.04+
