Open Manager for ComfyUI

Download Manager	Model Library
Resource Monitor	Desktop Mode

The whole workspace at once: one screenshot.

open_manager_preview.mp4

A manager for the whole ComfyUI workspace, not just its nodes.

Packs	Browse the Comfy Registry, install from registry or GitHub, see what an install does before it runs
Workspace	Models on disk, downloads, memory, outputs, and your own files
For remote ComfyUI instances	A desktop on a tab of its own. No swapping between tools just to view outputs, or manage files
Off by default	Model Library, the monitor strip and Desktop Mode
Never	A node in your graph. Nothing is installed or built at load time

Open Manager is not affiliated with ComfyUI-Manager or the Comfy Registry.

Install

Mode	Result
Custom node	Sits beside ComfyUI-Manager. Its own sidebar tab
pip package	Replaces the official manager, under --enable-manager

# as a custom node
cd ComfyUI/custom_nodes
git clone https://github.com/WASasquatch/open-manager-comfyui.git

# or as the manager
pip uninstall comfyui-manager
pip install comfyui-open-manager
python main.py --enable-manager

Update	pip install --upgrade comfyui-open-manager
uv environment	uv pip install comfyui-open-manager. Pack requirements install through uv too
Portable build	Use its own interpreter: python_embeded\python.exe -m pip install ...
Name clash	Both packages own comfyui_manager. Uninstall the other first. Reinstalling it, or a desktop auto-update, puts it back
Log	--enable-manager writes user/comfyui.log, rotating to comfyui.prev.log and comfyui.prev2.log. OPEN_MANAGER_NO_LOG leaves it alone

Access keys (optional)

Set under Open Manager > Access keys. A variable, where set, is used instead.

For	Variables	Get one at
Gated and private models	HF_TOKEN, HUGGING_FACE_HUB_TOKEN, OPEN_MANAGER_HF_TOKEN	huggingface.co/settings/tokens
Starring, higher rate limit	GITHUB_TOKEN, GH_TOKEN, OPEN_MANAGER_GITHUB_TOKEN	github.com/settings/tokens
Scanning an install	VIRUS_TOTAL_KEY, VIRUSTOTAL_API_KEY, OPEN_MANAGER_VIRUSTOTAL_KEY	virustotal.com/gui/my-apikey

Packs

Every version	Flagged, withheld and banned included
Before you install	Findings, dependency changes, new nodes, hardware fit
Contents named	Binaries, pickles, wheels, bytecode
Licences	Per pack, sortable
Your own repos	By URL or owner/repo, kept in user/
Any ref	Branch, tag or commit
Workflow gaps	Missing nodes, and which pack won a duplicate name
Themes	Gradients, icons, backdrops
Fast sync	Whole registry in seconds

Findings reword the confirmation. A registry ban blocks Install until Install versions the registry has banned is on.

Beyond packs

Four pieces. None of them adds a node to your graph.

		Default
Download Manager	Fetches the models a workflow needs: resumes, verifies, picks the drive	on
Model Library	What is on disk across every registered folder: duplicates, unreferenced files, storage	off
Resource Monitor	CPU, RAM, VRAM and temperatures in ComfyUI's control bar, with a Memory panel behind it	strip off, Memory button on
Desktop Mode	Files, notes, outputs and programs on a tab of their own	off, and needs OPEN_MANAGER_ENABLE_DESKTOP

Every panel opens as a movable window, or centred on the page. One setting each.

Remote installs

Desktop Mode is served by ComfyUI's own server: no second port, no second login.

Server switches

Set to 1. What ships on is closed with a NO_ switch; what ships off is opened with its own.

Variable	Closes
OPEN_MANAGER_NO_INSTALL	Installing and removing packs
OPEN_MANAGER_NO_GITHUB	Adding and installing GitHub repositories
OPEN_MANAGER_NO_DOWNLOADS	Fetching models
OPEN_MANAGER_NO_RESTART	Restarting ComfyUI
OPEN_MANAGER_NO_KEYS	Writing access keys
OPEN_MANAGER_APPROVED_ONLY	Anything the registry has not approved

Variable	Opens
OPEN_MANAGER_ENABLE_DESKTOP	Desktop Mode, for readers who switch it on in the settings
OPEN_MANAGER_ENABLE_FILES	The file browser, for readers who switch it on in the settings
OPEN_MANAGER_FILE_WRITES	Renaming, moving, copying and deleting files, making folders, and saving text files and pictures
OPEN_MANAGER_ALLOW_BANNED	Installing versions the registry has banned, whatever the setting says

The server refuses what a closed switch governs and names the variable. Desktop Mode and the file browser are hidden rather than refused, and their settings do nothing until the machine opens them.

Reference

Where it appears

Interface	Way in
Current	A sidebar tab
Legacy menu (Settings -> Comfy -> Use new menu -> Disabled)	An Open Manager button on that menu
Where it replaces the manager	The top menu's Extensions button as well

Extensions follows ComfyUI: the panel on the modern interface, the classic menu of destinations under --enable-manager-legacy-ui. Override it under What the Extensions button opens. Both carry every destination, and the sidebar tab is unaffected.

Network

Open Manager reads the Comfy Registry live. What it contacts:

Host	When
api.comfy.org	Browsing and installing
cdn.comfy.org	Downloading a registry version to install
codeload.github.com	Downloading a GitHub repository to install
raw.githubusercontent.com	Licences, READMEs, images
api.github.com	Pack stats and gallery, branches, tags and commits, starring, licence lookup
pypi.org	Checking for a newer Open Manager
www.virustotal.com	Scanning an install, with a key
huggingface.co, github.com and their download hosts	Model downloads. OPEN_MANAGER_MODEL_HOSTS adds others
Wherever a pack points	Pack icons. README and gallery images given as absolute URLs, unless Read pack README and repository metadata is off

Settings

Under Settings -> Open Manager.

Trust	Answer once per author, or every time

A GitHub token, set under Open Manager > Access keys or as GITHUB_TOKEN, raises 60 anonymous calls an hour to 5,000. Without one, pack pages still show README, gallery and versions.

The registry address is BASE_URL in open_manager/registry.py, and BASE in open_manager/catalog.py for the offline copy. Both can point at a mirror or a private index.

Trust

Asked	Before installing a pack from GitHub, loading a workflow from a pack, or downloading a model. Registry installs too, with Ask before installing a registry pack from an untrusted author on
Remembered in	user/open_manager/trusted_authors.json
Never	Hides a finding

Requirements

torch, torchaudio, torchsde and torchvision are never installed from a pack's requirements: they carry the build your ComfyUI was set up with. Anything held back is named in the install output. To substitute a package, map it in user/open_manager/pip_overrides.json:

{ "opencv-python": "opencv-python-headless>=4.9" }

Your GitHub list

Add	By URL or as owner/repo
Behaves like	A registry pack: installs, updates, uninstalls
Written to	user/open_manager/github_sources.json, outside the pack, so it survives an uninstall
Remove from list	Delists and uninstalls in one step

For pack authors

Declare a [tool.open_manager] table in pyproject.toml and every Open Manager user sees it. Every field is optional. Packs without the table are unaffected.

Field	Gives you
capabilities	What your pack does, as its own panel on your page
release_note	Your words above the version list, not a changelog guess
incompatible	Name a package and version; users are warned before installing
source	Say GitHub and the panel recommends it over the registry copy
themes	Ship colour palettes with gradients, icons, backdrops and rulers
example_workflows	Loadable from your page, with thumbnails
gallery	Screenshots from your repo or elsewhere
docs, funding	Buttons in your page header

[tool.open_manager]
incompatible = ["numpy>=2.0"]                   # declare known conflicts with other packages
source = "github"                               # prefer installing from the repository
branch = "main"                                 # named in the GitHub recommendation
docs = "https://example.com/docs"               # documentation URL
funding = "https://ko-fi.com/you"               # funding URL
release_note = "1.4.0 needs config regen."      # shown above the version list, 600 chars
capabilities = [                                # what your pack does, its own page panel
  "filesystem", "network", "subprocess",        #   from a fixed list, see below
]
example_workflows = ["workflows/*.json"]        # a path, a glob, or a directory
themes = ["themes/my-theme.json"]               # list themes to offer
gallery = [                                     # shown off on the pack page, up to 24, `png`,
                                                # `jpg`, `jpeg`, `gif`, `webp`, `avif`, and
                                                # `mp4`, `webm`, `mov`, `m4v` for clips
  "docs/*.png",                                 #   a path or glob in your repository
  "https://cdn.example.com/after.webp",         #   or a file hosted anywhere
]

Left out	Falls back to
example_workflows	workflows/, workflow/, examples/, example/, example_workflows/
docs, funding	[project.urls]
An installed pack's fields	The copy on disk, then the repository

Workflow thumbnails are not declared. An image beside a workflow and named for it is paired with it automatically, following ComfyUI's workflow templates convention: workflows/hdr.json picks up workflows/hdr.webp, .png, .jpg, .jpeg or .gif, and a numbered variant such as hdr-1.png counts too. Workflows without one show as a plain row.

Capabilities

Your own account of what your pack does, in fixed words so that two packs describe themselves the same way.

filesystem network subprocess binaries environment dynamic_code packages models credentials telemetry compilation hardware

Outside the list	Refused, and named on your page as unrecognised
Case and hyphens	Forgiven. Dynamic-Code resolves to dynamic_code
Declaring nothing	No panel
Not a substitute for	The archive inspection, which reads what is actually in the box

Themes

A ComfyUI colour palette plus an optional extras block: gradient or flat headers per node category or class, a title icon, an image behind node bodies, see-through bodies, a graph backdrop, shadow colours and a selection glow. Packs ship them, users add them from the pack page.

[tool.open_manager]
themes = ["themes/my-theme/my-theme.json"]
