ComfyUI provides a modular node graph and backend for generative workflows across images, video, audio and 3D. Local model workflows and optional paid API nodes have different dependencies.
Project overview
Visual workflows, memory offloading and custom-node management provide a configurable generation workflow; model requirements and enabled external API paths still matter.

Best for
Creators designing generative workflows with a visual node graph.
Users evaluating local model execution with external API nodes disabled.
Key capabilities
A nodes, graph, and flowchart interface to experiment and create complex Stable Diffusion workflows without needing to code anything.
Natively supports a wide range of models for generating images, videos, audio and 3D.
The source describes smart offloading for running large models with as little as 1GB VRAM. Check the actual requirements of your chosen models and workflows.
The core supports offline model execution and does not download resources unless requested by the user. Optional API nodes use external providers and can be disabled.
Optional API nodes to use paid models from external providers through the Comfy API, which can be disabled.
App Mode exposes sophisticated workflows through a simple UI.
Extension allowing users to easily install, update, and manage custom nodes.
Limitations and risks
Python 3.14 works but some custom nodes may have issues.
Commits outside of the stable release tags may be very unstable and break many custom nodes.
The generated TLS/SSL certificate is self-signed and not appropriate for shared or production use.
Getting started
Download and install the desktop application for an initial setup.
