ComfyUI Manager

ComfyUI Manager adds package management to ComfyUI, the node-based interface for Stable Diffusion and other generative models. From a graphical panel, users install, update, disable, and remove custom nodes drawn from a hub of hundreds of community node packs, and when a shared workflow references nodes that are missing, the manager identifies and fetches them. It also downloads models, shares workflows to platforms such as OpenArt and YouML, and provides snapshot functionality that captures the state of an installation so a working setup can be backed up and restored after a bad update. Installation is git based with support for pip and uv dependency handling, configurable security policy levels guard against untrusted node sources, and the cm-cli command line tool covers automation and headless servers. Written by ltdrdata and released under the GPL-3.0 license, it is commonly installed alongside ComfyUI by anyone who relies on custom nodes.
