comfy-forge

comfy-forge is the umbrella name for a family of tools that make ComfyUI custom nodes more easily installable, isolatable, and testable:

Project	What it does	Docs
comfy-env	Environment management and automatic CUDA wheel resolution for custom nodes: isolated pixi environments, persistent subprocess workers, transparent proxying.	Architecture
comfy-test	Installation testing infrastructure: installs a nodepack the way a user would, on a real platform matrix (Linux/Windows/macOS, CPU/CUDA, portable/desktop), and publishes results.	Overview
cuda-wheels	Prebuilt CUDA wheel farm: flash-attn, nvdiffrast, pytorch3d and friends, compiled across the Python x torch x CUDA x OS matrix and served as a pip simple index.	Overview

The three fit together like this: cuda-wheels builds the binaries nobody should have to compile, comfy-env delivers and isolates them (and everything else) on the user's hine, and comfy-test proves the whole thing actually installs and runs, on every platform ComfyUI users really have.
