This repository hosts a collection of nodes developed for ComfyUI. It aims to share useful components that enhance the functionality of ComfyUI projects. Some nodes are forks or versions of nodes from other packs, some are bespoke, and some are experimental and are quite useless, so they have been marked with a Caution label in this document.

Installation instructions

Configuration (only needed for Groq nodes)

Make a copy of .env.example and remove the .example from the name.
The new file should now be named .env without a normal file name, just a .env extension.
The file should be in the root of the node pack, so the same directory that the .example was in.
Edit .env with a text editor and edit the API key value inside.

Nodes

🔀 Batch Wildcard Upscale Sampler

Resolves wildcards and LoRA loading independently for every image, and can upscale the results (like Hires-fix), but processes them sequentially rather than as a true batch. Adapted from ChronoKnight's code. <img width="2175" height="639" alt="image" src="https://github.com/user-attachments/assets/14da44c8-4c23-40c9-9c44-35d9f9b8313e" />
