Practical overview
When it fits
Use ComfyUI when a media task benefits from a configurable, reusable node graph, or when a workflow needs to be exposed through an API or simplified with App Mode.
Who it is for
- Visual creators who want to control models, parameters and generation steps.
- Developers integrating reusable AI workflows into applications or production pipelines.
- People who want to assemble and save node-based generation workflows.
Documented uses
- Connect generation and processing steps into a visual workflow.
- Generate or edit media with supported diffusion models and workflow templates.
- Save and reuse workflows, or integrate them through the API.
- Use tools such as inpainting, compositing, upscaling, frame interpolation and depth estimation.
Requirements & limits
The project documents desktop software for Windows and macOS, manual installation for Windows, Linux and macOS, and an official paid cloud version. Core functionality can run offline; optional paid API nodes can be disabled.
- Local installation choice depends on operating system and available hardware; the project lists support for NVIDIA, AMD, Intel, Apple Silicon and Ascend GPU types for manual installation.
- ComfyUI is a workflow application and backend, not a diffusion model; users work with supported models and their associated components.
- The API supports integration into applications and production pipelines, while the node graph is the visual authoring interface.
- Optional partner/API nodes provide access to some closed-source models; the core can also run offline.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Run ComfyUI from an existing installation
Start ComfyUI using its documented Python entry point.
Before you start
- An existing ComfyUI installation.
- Python and dependencies configured for that installation.
Steps
From the ComfyUI directory, run the command below.
python main.pyUse the running ComfyUI interface to work with node-graph workflows.
Expected outcome
ComfyUI starts using its documented entry point and provides its node-graph interface.
Guide limitations
- The source documents the launch command but not installation steps, model setup, or a generation workflow.
- The source does not specify hardware requirements for this procedure.
