ComfyUI - Visual AI Workflow

Can I run ComfyUI locally on my own hardware, or do I need to use their cloud service?

ComfyUI offers Comfy Desktop for local execution on your own machine, so you're not locked into cloud processing. The node-based engine also works as open-source software you can self-host, giving you full flexibility to choose between local, cloud, or API-based deployment depending on your project needs.

Does ComfyUI support custom nodes and extensions beyond the built-in library?

Yes, ComfyUI is highly extensible and has over 60,000 nodes available through its community library, plus support for custom node development. The platform is built on open-source foundations, so developers regularly create and share new nodes; you can add them to your installation to expand what workflows can do.

Can I export ComfyUI workflows to use in production, or are they locked to the app?

ComfyUI offers a Comfy API for production endpoints, so you can deploy workflows beyond the desktop or cloud interface. This means you can build and test a node graph visually, then integrate it into a production pipeline or automate it at scale through their API layer.

Is there a simpler interface if I don't want to work with the node graph?

ComfyUI includes App Mode, which provides a simplified interface for users who prefer not to work with nodes. This lets beginners or team members less familiar with node-based workflows operate the software more intuitively while still accessing the same underlying models and processing power.
