ComfyUI Extension: ComfyUI-Dev-Utils

ComfyUI-Dev-Utils Introduction

ComfyUI-Dev-Utils is an extension designed to enhance the functionality of ComfyUI, a user interface for AI artists. This extension provides a suite of tools that help you analyze and optimize your workflows, making it easier to manage and debug your AI projects. Whether you're looking to track execution times, manage logs, or streamline your node connections, ComfyUI-Dev-Utils offers features that can significantly improve your experience.

How ComfyUI-Dev-Utils Works

ComfyUI-Dev-Utils works by integrating directly into the ComfyUI environment. Once installed, it adds various utilities and enhancements that you can use to monitor and manage your workflows. For example, it can display execution times for different nodes, capture and display logs, and provide options for rerouting node connections. These tools are designed to be intuitive and easy to use, even if you don't have a strong technical background.

ComfyUI-Dev-Utils Features

1. Execution Time Analysis Tool

This tool helps you understand how long each node in your workflow takes to execute. It adds a badge to the upper left corner of each node, displaying its execution time. Additionally, an Execution Time node can be added to show a table of execution times for all nodes, including the current and last execution times, as well as their differences.

• Badge Display: Shows execution time directly on the node.
• Execution Time Node: Displays a table of execution times.
• Clear Execution Cache: A button in the sidebar menu to clear the current cache, unload models, and free memory.

2. Log Console

The Log Console captures and displays Python logs, making it easier to debug your workflows. It automatically captures the output of print, logging, stdout, and stderr, and sends it to the web page via Server-Sent Events (SSE).

• Features:
• Based on SSE, not WebSocket, ensuring it doesn't affect ComfyUI's performance.
• Supports text color to differentiate error logs.
• Lazy startup, only capturing logs when needed.
• Option to completely disable the Log Console.

3. Reroute Enhancement

This feature adds a "Reroute" option to the node slot menu, making it easier to manage complex workflows. It also optimizes the process of deleting reroute nodes.

• Before and After Reroute:
• Before and After Deleting Reroute Node:

4. UrlDownload Node

This node allows you to download files from a remote URL and get the file path, making it easier to incorporate external resources into your workflows.

5. UploadAnything Node

This node lets you upload any file and get its file path, providing flexibility in managing various types of input files.
