About
ComfyUI swaps the usual single prompt box for a node graph: a checkpoint loader node feeds into a sampler node, which feeds into a VAE decode node, and so on, so the exact steps a diffusion model takes are visible and editable rather than hidden behind a slider. Wire in a ControlNet or LoRA node partway through and it slots into the same graph, with no separate plugin system layered on top.

Capability
bolt
Node-based image graph
Every step of a diffusion pipeline (model load, sampling, VAE decode, upscaling) is its own node, so you can rewire, swap, or inspect any part of the process.
lock
Drop-in ControlNet and LoRA support
Extra conditioning nodes plug into the same graph as everything else, with no separate extension system to manage.
extension
Portable, no-install option
A self-contained Windows build ships alongside the standard pip install, for anyone who'd rather not set up a Python environment first.
