ComfyUI has become a popular choice for creators in 2024. Setting it up correctly is crucial for getting the best performance, as the right configuration can make a big difference. One great option is using MimicPC, which lets you launch ComfyUI online without needing to download or install anything on your computer. This saves time and also allows you to use cloud storage for your projects. In this blog, we’ll share the best setup practices to help you get started smoothly.
What is ComfyUI?
ComfyUI is a versatile, node-based graphical user interface (GUI) for Stable Diffusion, designed to simplify the image generation process. Unlike traditional GUIs, ComfyUI allows users to visually connect different components of their workflows, making it intuitive to customize and optimize image generation settings. Currently, ComfyUI not only supports Stable Diffusion but also enables users to launch Flux, expanding its functionality and versatility.
Features and Advantages:
- Configurability: Users can easily adjust parameters and combine various nodes to create unique workflows tailored to their needs.
- Efficiency: The lightweight design ensures faster processing and lower memory usage compared to more complex GUIs.
- Transparency: ComfyUI provides a clear view of the workflow, helping users understand the underlying processes, which enhances learning and troubleshooting.
By leveraging a node-based system, ComfyUI empowers both beginners and advanced users to prototype, share, and refine their workflows effortlessly, making it a preferred choice among AI creation enthusiasts.
Now that you know the power of ComfyUI, you must be eager to try it out! You have two options to get started: you can install it on your computer locally or launch it in the cloud online for a hassle-free experience.
Setting Up ComfyUI Online with MimicPC
1. Using ComfyUI with MimicPC
MimicPC is a free online AI generator platformthat allows users to run applications like ComfyUI directly in their web browser, eliminating the need for downloads or installations. This service is ideal for those looking to use ComfyUI without the technical complexities of local setups.
2. Configuring Initial Settings
Once you've accessed ComfyUI through MimicPC, launch the application to see the default workflow for the text-to-image interface. Familiarize yourself with the layout, focusing on the nodes and parameters available. Adjust settings like resolution and output formats as per your preferences.
3. Selecting Models
To start generating images, selecting the right model is crucial. Locate the Load Checkpoint node, which allows you to choose from available Stable Diffusion or Flux checkpoint models. Click on the model name to open a dropdown list. If your desired model isn't showing, ensure it's correctly added to your MimicPC workspace.
4. Entering Prompts
You can enter your creative input directly in the designated nodes. There are typically two nodes labeled CLIP Text Encode (Prompt). The top node is for your primary prompt, while the lower one is for negative prompts—phrases you want the model to avoid. Craft your prompts thoughtfully to guide the AI effectively.
5. Installing Nodes
ComfyUI features a node-based system that allows you to expand its capabilities. If you need additional functionality, you can install custom nodes. Check the ComfyUI GitHub or community forums for available nodes and follow the provided installation instructions to integrate them seamlessly.
6. Generate Your Image
If everything is ready, click "Queue Prompt" to generate your image. The system will process your inputs and create the output based on your configured settings and prompts.

3. Extract and Set Up
- After downloading, extract the files using 7-Zip or WinRAR to your desired directory.
- Navigate to the folder containing the extracted files.
4. Run ComfyUI
- For Windows users, locate and run the `run_nvidia_gpu.bat` file to start ComfyUI in your web browser.
5. Install Additional Components
- Download the ComfyUI Manager batch file to help manage custom nodes, placing it in the ComfyUI installation folder. Run this batch file to complete the setup.
How to Install ComfyUI on Windows
Step 1: Install 7-Zip
- Visit the [7-Zip download page].
- Download the appropriate version for your system (32-bit or 64-bit).
- Run the downloaded `.exe` file and follow the installation instructions.
Step 2: Download and Extract ComfyUI
- Go to the [ComfyUI GitHub repository].
- Download the standalone version using the provided link or by cloning the repository.
- Once downloaded, right-click on the `ComfyUI_windows_portable_nvidia_cu118_or_cpu.7z` file, select Show More Options > 7-Zip > Extract Here. This will create a new folder called `ComfyUI_windows_portable`.
Step 3: Download a Checkpoint Model
To use ComfyUI, you need a checkpoint model:
- You can either download a model directly or share one from other Stable Diffusion GUIs like AUTOMATIC1111.
- Place the downloaded model in the folder: `ComfyUI_windows_portable\ComfyUI\models\checkpoints`.
Step 4: Launch ComfyUI
- If you have an Nvidia GPU, double-click `run_nvidia_gpu.bat` to start ComfyUI.
- If you don’t have an Nvidia GPU, double-click `run_cpu.bat` to launch ComfyUI in CPU mode, which may be slower.
- ComfyUI should automatically open in your web browser, allowing you to start generating images.
