Getting Started

Installing

You must have Python 3.10, 3.11 or 3.12 installed. On Windows, download the latest Python from the Python website.

On macOS, you will need Python 3.10, 3.11 or 3.12, which is easy to install using brew: brew install [email protected]. You can check which version of Python you have installed using python --version.

When using Windows, open the Windows Powershell app. Then observe you are at a command line, and it is printing "where" you are in your file system: your user directory (e.g., C:\Users\doctorpangloss). This is where a bunch of files will go. If you want files to go somewhere else, consult a chat bot for the basics of using command lines, because it is beyond the scope of this document. Then:

Create a virtual environment:
```
python -m venv venv
```

Activate it on Windows (PowerShell):

Set-ExecutionPolicy Unrestricted -Scope Process
& .\venv\Scripts\activate.ps1

Linux and macOS

source ./venv/bin/activate

Run the following command to install comfyui into your current environment. This will correctly select the version of torch that matches the GPU on your machine (NVIDIA or CPU on Windows, NVIDIA, Intel, AMD or CPU on Linux, CPU on macOS):
```
pip install "comfyui[withtorch]@git+https://github.com/hiddenswitch/ComfyUI.git"
```
Recommended: Currently, torch 2.5.0 is the latest version that xformers is compatible with. On Windows, install it first, along with xformers, for maximum compatibility and the best performance without advanced techniques in ComfyUI:
```
pip install torch==2.5.1+cu121 torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
pip install --no-build-isolation --no-deps xformers==0.0.28.post3 --index-url https://download.pytorch.org/whl/
pip install comfyui@git+https://github.com/hiddenswitch/ComfyUI.git
```
To enable torchaudio support on Windows, install it directly:
```
pip install torchaudio==2.5.0+cu121 --index-url https://download.pytorch.org/whl/cu121
```
Advanced: If you are running in Google Collab or another environment which has already installed torch for you; or, if you are an application developer:
```
# You will need wheel, which isn't included in Python 3.11 or later
pip install wheel
pip install --no-build-isolation comfyui@git+https://github.com/hiddenswitch/ComfyUI.git
```
This will use your pre-installed torch. This is also the appropriate dependency for packages, and is the one published to pypi. To automatically install with torch nightlies, use:
```
pip install comfyui[withtorchnightlies]@git+https://github.com/hiddenswitch/ComfyUI.git
```
Create the directories you can fill with checkpoints:
```
comfyui --create-directories
```
Your current working directory is wherever you started running comfyui. You don't need to clone this repository, observe it is omitted from the instructions. You can cd into a different directory containing models/, or if the models are located somehwere else, like C:/some directory/models, do:
```
comfyui --cwd="C:/some directory/"
```
You can see all the command line options with hints using comfyui --help.
To run the web server:
```
comfyui
```
When you run workflows that use well-known models, this will download them automatically.

To make it accessible over the network:
```
comfyui --listen
```

On Windows, you will need to open PowerShell and activate your virtual environment whenever you want to run comfyui.

& .\venv\Scripts\activate.ps1
comfyui

Upgrades are delivered frequently and automatically. To force one immediately, run pip upgrade like so:

pip install --no-build-isolation --no-deps --upgrade comfyui@git+https://github.com/hiddenswitch/ComfyUI.git

Advanced: Using uv:

uv is a significantly faster and improved Python package manager. On Windows, use the following commands to install the package from scratch about 6x faster than vanilla pip:

uv venv --seed
& .\venv\Scripts\activate.ps1
uv pip install comfyui[withtorch]@git+https://github.com/hiddenswitch/ComfyUI.git
python -m comfy.cmd.main

LTS Custom Nodes

These packages have been adapted to be installable with pip and download models to the correct places:

ELLA T5 Text Conditioning for SD1.5: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-ella.git
IP Adapter: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-ipadapter-plus
ControlNet Auxiliary Preprocessors: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-controlnet-aux.git.
LayerDiffuse Alpha Channel Diffusion: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-layerdiffuse.git.
BRIA Background Removal: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-bria-bg-removal.git
Video Frame Interpolation: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-video-frame-interpolation
Video Helper Suite: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-video-helper-suite
AnimateDiff Evolved: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-animatediff-evolved
Impact Pack: pip install git+https://github.com/AppMana/appmana-comfyui-nodes-impact-pack
TensorRT: pip install git+https://github.com/AppMAna/appmana-comfyui-nodes-tensorrt

Custom nodes are generally supported by this fork. Use these for a bug-free experience.

Request first-class, LTS support for more nodes by creating a new issue. Remember, ordinary custom nodes from the ComfyUI ecosystem work in this fork. Create an issue if you experience a bug or if you think something needs more attention.

Running with TLS

To serve with https:// on Windows easily, use Caddy. Extract caddy.exe to a directory, then run it:

caddy reverse-proxy --from localhost:443 --to localhost:8188 --tls self_signed

Notes for AMD Users

Until a workaround is found, specify these variables:

RDNA 3 (RX 7600 and later)

export HSA_OVERRIDE_GFX_VERSION=11.0.0
comfyui

RDNA 2 (RX 6600 and others)

export HSA_OVERRIDE_GFX_VERSION=10.3.0
comfyui

Model Downloading

ComfyUI LTS supports downloading models on demand. Its list of known models includes the most notable and common Stable Diffusion architecture checkpoints, slider LoRAs, all the notable ControlNets for SD1.5 and SDXL, and a small selection of LLM models. Additionally, all other supported LTS nodes will download models using the same mechanisms. This means that you will save storage space and time: you won't have to ever figure out the "right name" for a model, where to download it from, or where to put it ever again.

Known models will be downloaded from Hugging Face or CivitAI. Hugging Face has a thoughtful approach to file downloading and organization. This means you do not have to toil about having one, or many, files, or worry about where to put them.

On Windows platforms, symbolic links should be enabled to minimize the amount of space used: Enable Developer Mode in the Windows Settings, then reboot your computer. This way, Hugging Face can download models into a common place for all your apps, and place small "link" files that ComfyUI and others can read instead of whole copies of models.

To disable model downloading, start with the command line argument --disable-known-models: comfyui --disable-known-models. However, this will generally only increase your toil for no return.

Manual Install (Windows, Linux, macOS) For Development

Clone this repo:

git clone https://github.com/hiddenswitch/ComfyUI.git
cd ComfyUI

Create a virtual environment:

Create an environment:
```
python -m virtualenv venv
```

Activate it:

Windows (PowerShell):

Set-ExecutionPolicy Unrestricted -Scope Process
& .\venv\Scripts\activate.ps1

Linux and macOS

source ./venv/bin/activate

Then, run the following command to install comfyui into your current environment. This will correctly select the version of pytorch that matches the GPU on your machine (NVIDIA or CPU on Windows, NVIDIA AMD or CPU on Linux):
```
pip install -e ".[dev]"
```
To run the web server:
```
comfyui
```
To run tests:
```
pytest -v tests/
```
You can use comfyui as an API. Visit the OpenAPI specification. This file can be used to generate typed clients for your preferred language.

To create the standalone binary:

python -m PyInstaller --onefile --noupx -n ComfyUI --add-data="comfy/;comfy/" --paths $(pwd) --paths comfy/cmd main.py

Because pip installs the package as editable with pip install -e ., any changes you make to the repository will affect the next launch of comfy. In IDEA based editors like PyCharm and IntelliJ, the Relodium plugin supports modifying your custom nodes or similar code while the server is running.

Linux Development Dependencies

apt install -y git build-essential clang python3-dev python3-venv

Large Language Models

ComfyUI LTS supports text and multi-modal LLM models from the transformers ecosystem. This means all the LLaMA family models, LLAVA-NEXT, Phi-3, etc. are supported out-of-the-box with no configuration necessary.

In this example, LLAVA-NEXT (LLAVA 1.6) is prompted to describe an image.

You can try the LLAVA-NEXT, Phi-3, and two translation workflows.

SVG Conversion and String Saving

ComfyUI LTS supports powerful SVG conversion capabilities using vtracer and Skia, along with enhanced string saving functionality. This allows for seamless conversion between raster images and SVG format, as well as flexible string saving options.

In this example, a raster image is converted to SVG, potentially modified, and then converted back to a raster image. The resulting image and SVG code can be saved.

You can try the SVG Conversion Workflow to explore these features.

Video Workflows

ComfyUI LTS supports video workflows with AnimateDiff Evolved.

First, install this package using the Installation Instructions.

Then, install the custom nodes packages that support video creation workflows:

pip install git+https://github.com/AppMana/appmana-comfyui-nodes-video-frame-interpolation
pip install git+https://github.com/AppMana/appmana-comfyui-nodes-video-helper-suite
pip install git+https://github.com/AppMana/appmana-comfyui-nodes-animatediff-evolved
pip install git+https://github.com/AppMana/appmana-comfyui-nodes-controlnet-aux.git

Start creating an AnimateDiff workflow. When using these packages, the appropriate models will download automatically.

Custom Nodes

Custom Nodes can be added to ComfyUI by copying and pasting Python files into your ./custom_nodes directory.

Installing Custom Nodes

There are two kinds of custom nodes: vanilla custom nodes, which generally expect to be dropped into the custom_nodes directory and managed by a tool called the ComfyUI Extension manager ("vanilla" custom nodes) and this repository's opinionated, installable custom nodes ("installable").

Vanilla Custom Nodes

Clone the repository containing the custom nodes into custom_nodes/ in your working directory. Currently, this is not known to be compatible with ComfyUI Node Manager.

Run pip install git+https://github.com/owner/repository, replacing the git repository with the installable custom nodes URL. This is just the GitHub URL.

Authoring Custom Nodes

These instructions will allow you to quickly author installable custom nodes.

Using `pyproject.toml` for projects with existing `requirements.txt`

Suppose your custom nodes called my_comfyui_nodes has a folder layout that looks like this:

__init__.py
some_python_file.py
requirements.txt
LICENSE.txt
some_directory/some_code.py

First, add an __init__.py to some_directory, so that it is a Python package:

__init__.py
some_python_file.py
requirements.txt
LICENSE.txt
some_directory/__init__.py
some_directory/some_code.py

Then, if your NODE_CLASS_MAPPINGS are declared in __init__.py, use the following as a pyproject.toml, substituting your actual project name:

pyproject.toml

[project]
name = "my_comfyui_nodes"
description = "My nodes description."
version = "1.0.0"
license = { file = "LICENSE.txt" }
dynamic = ["dependencies"]

[project.urls]
Repository = "https://github.com/your-github-username/my-comfyui-nodes"
#  Used by Comfy Registry https://comfyregistry.org

[tool.comfy]
PublisherId = "your-github-username"
DisplayName = "my_comfyui_nodes"
Icon = ""

[build-system]
requires = ["setuptools", "wheel"]
build-backend = "setuptools.build_meta"

[tool.setuptools]
packages = ["my_comfyui_nodes", "my_comfyui_nodes.some_directory"]
package-dir = { "my_comfyui_nodes" = ".", "my_comfyui_nodes.some_directory" = "some_directory" }

[tool.setuptools.dynamic]
dependencies = { file = ["requirements.txt"] }

[project.entry-points."comfyui.custom_nodes"]
my_comfyui_nodes = "my_comfyui_nodes"

Observe that the directory should now be listed as a package in the packages and package-dir statement.

Using `setup.py`

Create a requirements.txt:

comfyui

Observe comfyui is now a requirement for using your custom nodes. This will ensure you will be able to access comfyui as a library. For example, your code will now be able to import the folder paths using from comfyui.cmd import folder_paths. Because you will be using my fork, use this:

comfyui @ git+https://github.com/hiddenswitch/ComfyUI.git

Additionally, create a pyproject.toml:

[build-system]
requires = ["setuptools", "wheel", "pip"]
build-backend = "setuptools.build_meta"

This ensures you will be compatible with later versions of Python.

Finally, move your nodes to a directory with an empty __init__.py, i.e., a package. You should have a file structure like this:

# the root of your git repository
/.git
/pyproject.toml
/requirements.txt
/mypackage_custom_nodes/__init__.py
/mypackage_custom_nodes/some_nodes.py

Finally, create a setup.py at the root of your custom nodes package / repository. Here is an example:

setup.py

from setuptools import setup, find_packages
import os.path

setup(
    name="mypackage",
    version="0.0.1",
    packages=find_packages(),
    install_requires=open(os.path.join(os.path.dirname(__file__), "requirements.txt")).readlines(),
    author='',
    author_email='',
    description='',
    entry_points={
        'comfyui.custom_nodes': [
            'mypackage = mypackage_custom_nodes',
        ],
    },
)

All .py files located in the package specified by the entrypoint with your package's name will be scanned for node class mappings declared like this:

some_nodes.py:

from comfy.nodes.package_typing import CustomNode


class Binary_Preprocessor(CustomNode):
    ...


NODE_CLASS_MAPPINGS = {
    "BinaryPreprocessor": Binary_Preprocessor
}
NODE_DISPLAY_NAME_MAPPINGS = {
    "BinaryPreprocessor": "Binary Lines"
}

These packages will be scanned recursively.

Extending the comfy.nodes.package_typing.CustomNode provides type hints for authoring nodes.

Adding Custom Configuration

Declare an entry point for configuration hooks in your setup.py that defines a function that takes and returns an configargparser.ArgParser object:

setup.py

setup(
    name="mypackage",
    ...
entry_points = {
    'comfyui.custom_nodes': [
        'mypackage = mypackage_custom_nodes',
    ],
    'comfyui.custom_config': [
        'mypackage = mypackage_custom_config:add_configuration',
    ]
},
)

mypackage_custom_config.py:

import configargparse


def add_configuration(parser: configargparse.ArgParser) -> configargparse.ArgParser:
    parser.add_argument("--openai-api-key",
                        required=False,
                        type=str,
                        help="Configures the OpenAI API Key for the OpenAI nodes", env_var="OPENAI_API_KEY")
    return parser

You can now see your configuration option at the bottom of the --help command along with hints for how to use it:

$ comfyui --help
usage: comfyui.exe [-h] [-c CONFIG_FILE] [--write-out-config-file CONFIG_OUTPUT_PATH] [-w CWD] [-H [IP]] [--port PORT]
                   [--enable-cors-header [ORIGIN]] [--max-upload-size MAX_UPLOAD_SIZE] [--extra-model-paths-config PATH [PATH ...]]
...
                   [--openai-api-key OPENAI_API_KEY]

options:
  -h, --help            show this help message and exit
  -c CONFIG_FILE, --config CONFIG_FILE
                        config file path
  --write-out-config-file CONFIG_OUTPUT_PATH
                        takes the current command line args and writes them out to a config file at the given path, then exits
  -w CWD, --cwd CWD     Specify the working directory. If not set, this is the current working directory. models/, input/, output/ and other
                        directories will be located here by default. [env var: COMFYUI_CWD]
  -H [IP], --listen [IP]
                        Specify the IP address to listen on (default: 127.0.0.1). If --listen is provided without an argument, it defaults to
                        0.0.0.0. (listens on all) [env var: COMFYUI_LISTEN]
  --port PORT           Set the listen port. [env var: COMFYUI_PORT]
...
  --distributed-queue-name DISTRIBUTED_QUEUE_NAME
                        This name will be used by the frontends and workers to exchange prompt requests and replies. Progress updates will be
                        prefixed by the queue name, followed by a '.', then the user ID [env var: COMFYUI_DISTRIBUTED_QUEUE_NAME]
  --external-address EXTERNAL_ADDRESS
                        Specifies a base URL for external addresses reported by the API, such as for image paths. [env var:
                        COMFYUI_EXTERNAL_ADDRESS]
  --openai-api-key OPENAI_API_KEY
                        Configures the OpenAI API Key for the OpenAI nodes [env var: OPENAI_API_KEY]

You can now start comfyui with:

comfyui --openai-api-key=abcdefg12345

or set the environment variable you specified:

export OPENAI_API_KEY=abcdefg12345
comfyui

or add it to your config file:

config.yaml:

openapi-api-key: abcdefg12345

comfyui --config config.yaml

Since comfyui looks for a config.yaml in your current working directory by default, you can omit the argument if config.yaml is located in your current working directory:

comfyui

Your entry point for adding configuration options should not import your nodes. This gives you the opportunity to use the configuration you added in your nodes; otherwise, if you imported your nodes in your configuration entry point, the nodes will potentially be initialized without any configuration.

Access your configuration from cli_args:

from comfy.cli_args import args
from comfy.cli_args_types import Configuration
from typing import Optional


# Add type hints when accessing args
class CustomConfiguration(Configuration):
    def __init__(self):
        super().__init__()
        self.openai_api_key: Optional[str] = None


args: CustomConfiguration


class OpenAINode(CustomNode):
    ...

    def execute(self):
        openai_api_key = args.open_api_key

Troubleshooting

I see a message like RuntimeError: '"upsample_bilinear2d_channels_last" not implemented for 'Half''

You must use Python 3.11 on macOS devices, and update to at least Ventura.

I see a message like Error while deserializing header: HeaderTooLarge

Download your model file again.

Using the Editor

Notes

Only parts of the graph that have an output with all the correct inputs will be executed.

Only parts of the graph that change from each execution to the next will be executed, if you submit the same graph twice only the first will be executed. If you change the last part of the graph only the part you changed and the part that depends on it will be executed.

Dragging a generated png on the webpage or loading one will give you the full workflow including seeds that were used to create it.

You can use () to change emphasis of a word or phrase like: (good code:1.2) or (bad code:0.8). The default emphasis for () is 1.1. To use () characters in your actual prompt escape them like \( or \).

You can use {day|night}, for wildcard/dynamic prompts. With this syntax "{wild|card|test}" will be randomly replaced by either "wild", "card" or "test" by the frontend every time you queue the prompt. To use {} characters in your actual prompt escape them like: \{ or \}.

Dynamic prompts also support C-style comments, like // comment or /* comment */.

To use a textual inversion concepts/embeddings in a text prompt put them in the models/embeddings directory and use them in the CLIPTextEncode node like this (you can omit the .pt extension):

embedding:embedding_filename.pt

How to increase generation speed?

Make sure you use the regular loaders/Load Checkpoint node to load checkpoints. It will auto pick the right settings depending on your GPU.

You can set this command line setting to disable the upcasting to fp32 in some cross attention operations which will increase your speed. Note that this will very likely give you black images on SD2.x models. If you use xformers or pytorch attention this option does not do anything.

--dont-upcast-attention

How to show high-quality previews?

Use --preview-method auto to enable previews.

The default installation includes a fast latent preview method that's low-resolution. To enable higher-quality previews with TAESD, download the taesd_decoder.pth (for SD1.x and SD2.x) and taesdxl_decoder.pth (for SDXL) models and place them in the models/vae_approx folder. Once they're installed, restart ComfyUI to enable high-quality previews.

Configuration

This supports configuration with command line arguments, the environment and a configuration file.

Configuration File

First, run comfyui --help for all supported configuration and arguments.

Args that start with -- can also be set in a config file (config.yaml or config.json or specified via -c). Config file syntax allows: key=value, flag=true, stuff=[a,b,c] (for details, see syntax here). In general, command-line values override environment variables which override config file values which override defaults.

Extra Model Paths

Copy docs/examples/configuration/extra_model_paths.yaml to your working directory, and modify the folder paths to match your folder structure.

You can pass additional extra model path configurations with one or more copies of --extra-model-paths-config=some_configuration.yaml.

  --executor-factory EXECUTOR_FACTORY
                        When running ComfyUI as a distributed worker, this specifies the kind of executor that should be used to run the actual ComfyUI workflow
                        worker. A ThreadPoolExecutor is the default. A ProcessPoolExecutor results in better memory management, since the process will be closed and
                        large, contiguous blocks of CUDA memory can be freed. [env var: COMFYUI_EXECUTOR_FACTORY]

Args that start with '--' can also be set in a config file (config.yaml or config.json or specified via -c). Config file syntax allows: key=value, flag=true, stuff=[a,b,c] (for details, see syntax at
https://goo.gl/R74nmi). In general, command-line values override environment variables which override config file values which override defaults.

Using ComfyUI as an API / Programmatically

There are multiple ways to use this ComfyUI package to run workflows programmatically:

Embedded

Start ComfyUI by creating an ordinary Python object. This does not create a web server. It runs ComfyUI as a library, like any other package you are familiar with:

from comfy.client.embedded_comfy_client import EmbeddedComfyClient

async with EmbeddedComfyClient() as client:
    # This will run your prompt
    # To get the prompt JSON, visit the ComfyUI interface, design your workflow and click **Save (API Format)**. This JSON is what you will use as your workflow.
    outputs = await client.queue_prompt(prompt)
    # At this point, your prompt is finished and all the outputs, like saving images, have been completed.
    # Now the outputs will contain the same thing that the Web UI expresses: a file path for each output.
    # Let's find the node ID of the first SaveImage node. This will work when you change your workflow JSON from
    # the example above.
    save_image_node_id = next(key for key in prompt if prompt[key].class_type == "SaveImage")
    # Now let's print the absolute path to the image.
    print(outputs[save_image_node_id]["images"][0]["abs_path"])
# At this point, all the models have been unloaded from VRAM, and everything has been cleaned up.

See script_examples/basic_api_example.py for a complete example.

Remote

Visit the ComfyUI interface, design your workflow and click Save (API Format). This JSON is what you will use as your workflow.

You can use the built-in Python client library by installing this package without its dependencies.

pip install aiohttp
pip install --no-deps git+https://github.com/hiddenswitch/ComfyUI.git

Then the following idiomatic pattern is available:

from comfy.client.aio_client import AsyncRemoteComfyClient

client = AsyncRemoteComfyClient(server_address="http://localhost:8188")
# Now let's get the bytes of the PNG image saved by the SaveImage node:
png_image_bytes = await client.queue_prompt(prompt)
# You can save these bytes wherever you need!
with open("image.png", "rb") as f:
    f.write(png_image_bytes)

See script_examples/remote_api_example.py for a complete example.

REST API

First, install this package using the Installation Instructions. Then, run comfyui.

Visit the ComfyUI interface, design your workflow and click Save (API Format). This JSON is what you will use as your workflow.

Then, send a request to api/v1/prompts. Here are some examples:

curl:

curl -X POST "http://localhost:8188/api/v1/prompts" \
     -H "Content-Type: application/json" \
     -H "Accept: image/png" \
     -o output.png \
     -d '{
       "prompt": {
         # ... (include the rest of the workflow)
       }
     }'

Python:

import requests

url = "http://localhost:8188/api/v1/prompts"
headers = {
    "Content-Type": "application/json",
    "Accept": "image/png"
}
workflow = {
    "4": {
        "inputs": {
            "ckpt_name": "sd_xl_base_1.0.safetensors"
        },
        "class_type": "CheckpointLoaderSimple"
    },
    # ... (include the rest of the workflow)
}

payload = {"prompt": workflow}

response = requests.post(url, json=payload, headers=headers)

Javascript (Browser):

async function generateImage() {
    const prompt = "a man walking on the beach";
    const workflow = {
        "4": {
            "inputs": {
                "ckpt_name": "sd_xl_base_1.0.safetensors"
            },
            "class_type": "CheckpointLoaderSimple"
        },
        // ... (include the rest of the workflow)
    };

    const response = await fetch('http://localhost:8188/api/v1/prompts', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json',
            'Accept': 'image/png'
        },
        body: JSON.stringify({prompt: workflow})
    });

    const blob = await response.blob();
    const imageUrl = URL.createObjectURL(blob);
    const img = document.createElement('img');
    // load image into the DOM
    img.src = imageUrl;
    document.body.appendChild(img);
}

generateImage().catch(console.error);

You can use the OpenAPI specification file to learn more about all the supported API methods.

OpenAPI Spec for Vanilla API, Typed Clients

Use a typed, generated API client for your programming language and access ComfyUI server remotely as an API.

You can generate the client from comfy/api/openapi.yaml.

RabbitMQ / AMQP Support

Submit jobs directly to a distributed work queue. This package supports AMQP message queues like RabbitMQ. You can submit workflows to the queue, including from the web using RabbitMQ's STOMP support, and receive realtime progress updates from multiple workers. Continue to the next section for more details.

Distributed, Multi-Process and Multi-GPU Comfy

This package supports multi-processing across machines using RabbitMQ. This means you can launch multiple ComfyUI backend workers and queue prompts against them from multiple frontends.

ComfyUI has two roles: worker and frontend. An unlimited number of workers can consume and execute workflows (prompts) in parallel; and an unlimited number of frontends can submit jobs. All of the frontends' API calls will operate transparently against your collection of workers, including progress notifications from the websocket.

To share work among multiple workers and frontends, ComfyUI uses RabbitMQ or any AMQP-compatible message queue like SQS or Kafka.

Example with RabbitMQ and File Share

On a machine in your local network, install Docker and run RabbitMQ:

docker run -it --rm --name rabbitmq -p 5672:5672 rabbitmq:latest

Find the machine's main LAN IP address:

Windows (PowerShell):

Get-NetIPConfiguration | Where-Object { $_.InterfaceAlias -like '*Ethernet*' -and $_.IPv4DefaultGateway -ne $null } | ForEach-Object { $_.IPv4Address.IPAddress }

Linux

ip -4 addr show $(ip route show default | awk '/default/ {print $5}') | grep -oP 'inet \K[\d.]+'

macOS

ifconfig $(route get default | grep interface | awk '{print $2}') | awk '/inet / {print $2; exit}'

On my machine, this prints 10.1.0.100, which is a local LAN IP that other hosts on my network can reach.

On this machine, you can also set up a file share for models, outputs and inputs.

Once you have installed this Python package following the installation steps, you can start a worker using:

Starting a Worker:

# you must replace the IP address with the one you printed above
comfyui-worker --distributed-queue-connection-uri="amqp://guest:[email protected]"

All the normal command line arguments are supported. This means you can use --cwd to point to a file share containing the models/ directory:

comfyui-worker --cwd //10.1.0.100/shared/workspace --distributed-queue-connection-uri="amqp://guest:[email protected]"

Starting a Frontend:

comfyui --listen --distributed-queue-connection-uri="amqp://guest:[email protected]" --distributed-queue-frontend

However, the frontend will not be able to find the output images or models to show the client by default. You must specify a place where the frontend can find the same outputs and models that are available to the backends:

comfyui --cwd //10.1.0.100/shared/workspace --listen --distributed-queue-connection-uri="amqp://guest:[email protected]" --distributed-queue-frontend

You can carefully mount network directories into outputs/ and inputs/ such that they are shared among workers and frontends; you can store the models/ on each machine, or serve them over a file share too.

Operating

The frontend expects to find the referenced output images in its --output-directory or in the default outputs/ under --cwd (aka the "workspace").

This means that workers and frontends do not have to have the same argument to --cwd. The paths that are passed to the frontend, such as the inputs/ and outputs/ directories, must have the same contents as the paths passed as those directories to the workers.

Since reading models like large checkpoints over the network can be slow, you can use --extra-model-paths-config to specify additional model paths. Or, you can use --cwd some/path, where some/path is a local directory, and, and mount some/path/outputs to a network directory.

Known models listed in model_downloader.py are downloaded using huggingface_hub with the default cache_dir. This means you can mount a read-write-many volume, like an SMB share, into the default cache directory. Read more about this here.

Containers

Build the Dockerfile:

docker build . -t hiddenswitch/comfyui

To run:

docker run -it -v ./output:/workspace/output -v ./models:/workspace/models --gpus=all --ipc=host --ulimit memlock=-1 --ulimit stack=67108864 --rm hiddenswitch/comfyui

Frontend Development

As of August 15, 2024, we have transitioned to a new frontend, which is now hosted in a separate repository: ComfyUI Frontend. This repository now hosts the compiled JS (from TS/Vue) under the web/ directory.

Reporting Issues and Requesting Features

For any bugs, issues, or feature requests related to the frontend, please use the ComfyUI Frontend repository. This will help us manage and address frontend-specific concerns more efficiently.

Using the Latest Frontend

The new frontend is now the default for ComfyUI. However, please note:

The frontend in the main ComfyUI repository is updated weekly.
Daily releases are available in the separate frontend repository.

To use the most up-to-date frontend version:

For the latest daily release, launch ComfyUI with this command line argument:
```
--front-end-version Comfy-Org/ComfyUI_frontend@latest
```
For a specific version, replace latest with the desired version number:
```
--front-end-version Comfy-Org/[email protected]
```

This approach allows you to easily switch between the stable weekly release and the cutting-edge daily updates, or even specific versions for testing purposes.

Accessing the Legacy Frontend

If you need to use the legacy frontend for any reason, you can access it using the following command line argument:

--front-end-version Comfy-Org/ComfyUI_legacy_frontend@latest

This will use a snapshot of the legacy frontend preserved in the ComfyUI Legacy Frontend repository.
