What is Minimalistic Comfy Wrapper Webui?
Minimalistic Comfy Wrapper WebUI (MCWW) is an additional non-node based web interface for ComfyUI that focuses on inference rather than workflow building. It dynamically adapts to your existing ComfyUI workflows by reading input and output node titles, converting them into a clean, minimalist UI without requiring workflow export or API format conversion. The tool is built on Gradio and provides a user-friendly alternative for users who find ComfyUI's node-based interface too complex for everyday generation tasks.
Key features include stable UI states that persist in browser local storage (so refreshing or closing the browser doesn't reset your work), a persistent queue saved to disk that survives PC power-offs and errors, preset management for saving and retrieving favorite text prompts with one click, and advanced queue management with task priority settings, reordering, pause, and resume capabilities. It supports batch processing where you can upload multiple input images or videos and run the workflow for each one. The interface works well on smartphones and supports Images, Video, Audio, and Text generation workflows including Flux Klein 9b, Wan2.2 A14b, Qwen TTS, and Whisper.
MCWW is designed for ComfyUI users who have already built stable workflows but want a simpler, more compact interface for running generations without constantly dealing with node connections. It's particularly suitable for users who find alternatives like SwarmUI or ViewComfy too complex, for mobile users who need a phone-friendly interface, and for creators who want to efficiently manage generation queues and save commonly used prompts as presets. The tool can be installed either as a ComfyUI extension (with a toolbar icon) or as an independent standalone server.

Frequently asked questions about Minimalistic Comfy Wrapper Webui
What is Minimalistic Comfy Wrapper WebUI?
MCWW is an additional non-node based web UI for ComfyUI focused on inference. It dynamically adapts to your existing ComfyUI workflows by converting input and output nodes into a minimalist interface. Built on Gradio, it provides stable UI states, presets for prompts, and an advanced queue management system without requiring workflow export.
How do I install MCWW?
You can install it in two ways: as a ComfyUI extension via ComfyUI Manager by searching for 'Minimalistic Comfy Wrapper WebUI' by light-and-ray, or as a standalone independent server by cloning the GitHub repository and configuring the .env file. You can also install via command line using 'comfy node install mcww-webui'.
How do I format node titles for MCWW?
Format titles as <Label:category:sortOrder> where category is things like 'prompt' or 'output', and sortOrder determines position. For example: <Image:prompt:1> for a Load Image node, <Prompt:prompt:1> for a text prompt node, and <Edited result:output:1> for a Save Image node. After formatting, click 'Refresh' to update the UI.
Does MCWW work with my existing ComfyUI workflows?
Yes, MCWW uses the same workflows as ComfyUI without needing export or API format conversion. Just edit your workflows in ComfyUI, format the input/output node titles properly, click 'Refresh' in MCWW, and the UI will automatically generate based on your workflow structure.
What types of generation workflows does MCWW support?
MCWW works for Images, Video, Audio, and Text generation workflows. It supports models like Flux Klein 9b, Wan2.2 A14b, Qwen TTS, and Whisper. Any ComfyUI workflow with properly formatted input/output nodes can be used.
How does the persistent queue work?
The queue is saved to storage/queue.bin file on MCMM startup and persists to disk. It survives errors, PC power-offs, and you can close Comfy or reboot during generation. You can set priority for tasks, reorder queue items, pause and resume the queue.
Can I use MCWW on my smartphone?
Yes, the interface is user-friendly on smartphones. The minimalist design and Gradio-based UI work well on mobile devices, making it convenient to run generations from your phone.
How do presets work in MCWW?
Presets let you save favorite text prompts and retrieve them with one click. You can save prompts in the project page and access them easily. Presets are very convenient when paired with the batch feature and are especially useful when you have too many presets to manage manually.
Can I use LoRAs with MCWW?
MCWW doesn't support LoRAs directly. You need to use them indirectly through the 'Prompt control' extension. There is detailed documentation available on how to use LoRAs in MCWW via this extension, which works well with the presets system.
What categories can I use in node titles?
Beyond basic categories like 'prompt' and 'output', you can use 'advanced' for nodes in the Advanced accordion under text prompt (like seed, steps), and 'important' for inputs that always change (like music duration, video frames). You can also specify column, row numbers, create custom accordions, and set min/max step values for numeric nodes.
