How to Install ComfyUI Manager to Add Nodes and Models Easily

Add the Manager extension so you can install custom nodes, fix missing nodes in shared workflows, and update everything from inside the interface.

6 minBeginner

Most useful workflows you find online rely on custom nodes that do not ship with ComfyUI. ComfyUI Manager is the extension that installs them for you, spots missing nodes in a workflow, and keeps everything updated. It is the first thing experienced users add after the base install.

What you need

A working ComfyUI install (portable or manual)
Git installed, or willingness to download a ZIP instead
Two minutes and a server restart

Step 1: Open the custom_nodes folder

Custom extensions live in ComfyUI\custom_nodes. Open a terminal there. On the Windows portable build that path is ComfyUI_windows_portable\ComfyUI\custom_nodes.

Step 2: Clone the Manager repo

Clone the project directly into custom_nodes. Git is the recommended route because the Manager can then update itself cleanly later.

terminal in custom_nodes

cd ComfyUI/custom_nodes
git clone https://github.com/Comfy-Org/ComfyUI-Manager.git

No Git? Use the ZIP

Download the repo as a ZIP from GitHub, extract it, and rename the folder to ComfyUI-Manager inside custom_nodes. The result is identical.

Step 3: Restart ComfyUI

Close the console window and launch ComfyUI again. On startup it imports the new node pack. If the import succeeds you will see a Manager button appear in the interface.

Step 4: Open the Manager panel

In the interface, click the Manager button. From here you can browse and install custom nodes, install models, update all packs at once, and run the install-missing-nodes scan.

The Manager menu is your control panel for everything add-on.

Step 5: Fix a workflow with missing nodes

When you load someone else's workflow and see red boxes, those are missing nodes. Open the Manager and click Install Missing Custom Nodes. It matches the red nodes against its registry, installs the packs, and after a restart the red boxes turn normal.

Custom nodes run real code

A custom node is a Python package that runs on your machine. Stick to well-known packs with many stars and recent activity, and be cautious about installing obscure ones just to open a random workflow.

Result: a Manager button in the interface that turns node installs and updates into a few clicks instead of manual git clones.
