The difference, not the feature list

Why Run ComfyUI on Diffus

ComfyUI is free and open source — the question is never whether it is good, it is who keeps 62 node packs, 70,000+ models and a GPU running for you.

3,300+ Nodes, Nothing to Install

62 custom node packs ship preinstalled — Impact Pack, KJNodes, WAS Node Suite, Comfyroll, LayerStyle, Easy-Use, Inspire Pack, controlnet_aux and more — on top of ComfyUI's 557 built-ins. No pip, no CUDA mismatch, no broken graph after an update.

Open ComfyUI

70,000+ Models Already Loaded

55,000+ LoRAs and 10,000+ checkpoints are on disk and selectable from any loader node. Paste a Civitai link to add one that isn't. A local ComfyUI makes you download every one of those yourself.

New Models the Week They Land

Flux, Qwen, Wan, LTX-Video, HunyuanVideo, Z-Image, SD 3.5, Nunchaku and GGUF quantisation are already wired up. We track the wrappers so your graph runs the new model instead of waiting on your own install.

Someone Else Owns the GPU

Graphs run on our cross-cloud GPU pool. Close the laptop mid-render, come back to the result. No 24 GB card to buy, no hourly instance to remember to shut down.

Someone Else's Workflow Just Runs

Drop in a workflow JSON, or a PNG carrying its metadata, and the nodes it references are almost certainly already installed — no red boxes, no hunting down the pack that broke the graph.

Open ComfyUI

Your Graphs Follow You

Workflows save to your account and reopen on any machine; outputs land in your gallery with their parameters attached instead of in a local folder.
