Mycraft (Alpha Experimental Version)

Mycraft provides a storyboard experience for image generation, powered by the ComfyUI API.

• Each container functions as an independent ComfyUI workflow.
• Supports workflows (text-to-text) and fine-tuning (image-to-image).
• Supports workflow customization.
• SDXL and Flux 1 Dev workflows supported by default.

Get Started

1. Installation

1. Install ComfyUI.

2. Clone this repository into the custom_nodes directory:

   cd ComfyUI/custom_nodes
   git clone https://github.com/uauaouau/mycraft-comfyui.git

3. Install ComfyUI Dependencies (custom nodes):

   git clone https://github.com/rgthree/rgthree-comfy.git
   git clone https://github.com/tsogzark/ComfyUI-load-image-from-url.git
   git clone git clone https://github.com/JPS-GER/ComfyUI_JPS-Nodes.git

4. Start ComfyUI.

5. Go to http://localhost:8188/mycraft.

Run Mycraft UI

Since you have installed Mycraft UI as ComfyUI Custom Node you can open your ComfyUI instance and add /mycraft to address like:

http://localhost:8188/mycraft

or

http://0.0.0.0:8188/mycraft

It works offline also.

Beautiful Lora Styles Catalog

⚠️ It is recommended to organize your LoRA files in a parent directory named after the model class.

For example, instead of placing a file at .../ComfyUI/models/loras/hello.safetensor, consider using a structure like .../ComfyUI/models/loras/sdxl/<filter-name>/hello.safetensor. While the directory name as a filter name is not mandatory, it is highly beneficial when using filters in the browser UI.

Civitai Lora Metadata

By default Mycraft uses Civitai API to get your LORA files metadata automatically when first start:

1. It gets checksum sha256 of all .safetensor files in .../ComfyUI/models/loras directory.
2. Find model metadata by checksums with Civitai API.
3. Generates lorashashes.json cache file in .../ComfyUI/custom_nodes/mycraft-comfyui/ directory.

To repeat this process manually you can press Update Loras button in Select Styles overlay.

Make shure you have checked on true the Settings - Use Styles List from Mycraft ComfyUI Plugin option.

Workflows

This project currently supports text-to-text and image-to-image workflows using the KSampler sampler for models:

• SDXL: workflows/sdxl.json
• Flux 1 Dev: workflows/flux.json

Settings for Flux 1 Dev Workflow

Please check the workflows/flux.json file and change weight_dtype value based on your needs:

  "12": {
    "inputs": {
      "unet_name": "flux1-dev.safetensors",
      "weight_dtype": "fp8_e4m3fn" // here
    },
    "class_type": "UNETLoader",
    "_meta": {
      "title": "Load Diffusion Model"
    }
  },

So as the CLIPs:

  "13": {
    "inputs": {
      "clip_name1": "t5xxl_fp16.safetensors", // here
      "clip_name2": "clip_l.safetensors", // here
      "type": "flux",
      "device": "default"
    },
    "class_type": "DualCLIPLoader",
    "_meta": {
      "title": "DualCLIPLoader"
    }
  },

Hotkeys

• [Select container] + Ctrl + D: Duplicate container
• [Select container] + Alt + Drag Mouse: Duplicate container
• [Select container] + Ctrl + X or Delete: Delete container
• Mouse Scroll: Zoom

Roadmap

This is the minimal viable product version of Mycraft. Currently, it includes basic functionality, but many innovations are planned for future updates. These will enable modular and abstract customization, allowing the UI to be tailored to specific tasks.

Third-Party Modules

This project uses the following dependencies to enhance the user experience:

• rgthree-comfy
• ComfyUI_JPS-Nodes
• ComfyUI-load-image-from-url
