comfyui-manager

What it is and what it does

ComfyUI-Manager is an extension that adds a management layer to ComfyUI, a node-based generative AI framework. It provides a graphical interface and command-line tools to discover, install, update, and remove custom nodes from a community registry (registry.comfy.org). The extension also handles configuration, snapshots of installation state, and workflow sharing to external platforms.

The package depends on GitPython and PyGithub for repository operations, transformers and huggingface-hub for model handling, and typer and rich for CLI and terminal output. It runs as part of ComfyUI's backend and is now installable via pip (as of v4.0) rather than requiring manual git cloning. The extension manages custom nodes through three database modes—cached channel data, local storage, or live remote queries—and supports rollback via snapshots saved to disk.

Use it for:

• Browse and install community-created custom nodes without manually cloning repositories or editing configuration files
• Update all installed custom nodes at once and roll back to a previous installation state via snapshots
• Share ComfyUI workflows to external platforms (comfyworkflows.com, openart.ai, youml.com) directly from the UI
• Manage custom node dependencies and resolve conflicts between extensions using the Manager's conflict detection
• Use cm-cli command-line tools to automate custom node installation and management without running the ComfyUI GUI

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Installs, removes, disables, and enables custom nodes for ComfyUI, plus provides a hub interface to browse and manage a registry of community extensions.

Yes. ComfyUI-Manager is actively maintained, has no known vulnerabilities, and low install friction. It is essential for anyone using ComfyUI who wants to manage custom nodes without manual repository cloning. The GPL-3.0 copyleft license is standard for the ComfyUI ecosystem. Install it if you use ComfyUI; it is now a dependency of ComfyUI itself in recent versions.

Install

Installing comfyui-manager

Before you install

Low friction: pure Python wheel with no compiled dependencies. Active maintenance (last commit 2026-08-13, 61 days since release). Requires Python 3.9+. Depends on GitPython, PyGithub, transformers, huggingface-hub, typer, rich, and others—a moderately sized dependency tree but all are standard Python packages.

License in practice

GPL-3.0-only (copyleft): any derivative work or modification must also be licensed under GPL-3.0. If you modify the source or bundle it with proprietary code, you must disclose those modifications and license them under GPL-3.0 as well.

Quickstart

pip install comfyui-manager

from comfyui_manager import manager
# Typically invoked via ComfyUI's web UI Manager button or cm-cli command-line tools

Requires ComfyUI to be installed separately; designed as an extension to ComfyUI, not a standalone tool. Python 3.9 or later required.

Verify before relying

• Whether transformers and huggingface-hub are always needed at runtime or only for specific features
• Performance impact of the three DB modes (Channel cache, Local, Channel remote) on large custom-node registries
• Snapshot restore reliability for custom nodes not managed by Git
