ComfyUI-Crystools

Why we included this project

Working with ComfyUI day in and day out, you quickly notice how much time goes into babysitting the server. This extension puts a live readout of CPU, GPU, RAM, VRAM, GPU temperature, and disk usage directly in the menu bar, so you can catch a memory leak before a render crawls. The progress bar shows time elapsed and lets you click to jump to the node that is currently running, which is a small but enormous help when a batch fails halfway. It also adds nodes for reading image metadata, comparing two images or two JSON payloads, and saving and previewing images with more control, exposing details you would otherwise have to dig out of a saved workflow. For anyone who lives in ComfyUI and keeps hitting memory limits, this is one of those utilities that becomes second nature fast.
