How many nodes are available?

62 custom node packs are preinstalled, contributing about 2,750 node types, on top of the 557 built into ComfyUI 0.29 — about 3,300 in total. That covers the packs most published workflows depend on, so an imported graph usually runs without hunting down missing nodes.

Can I install my own custom node?

Not directly. The environment is shared, so one user installing a pack could break everyone else's graphs. Tell us which pack you need and we install it for you — the 62 packs here grew out of exactly those requests.

No. Graphs execute on our cross-cloud GPU pool, so a laptop or a tablet browser is enough. Nothing to install and nothing to keep updated.

Can I use my own models?

Yes. Paste a Civitai model URL and Diffus imports it, or upload your own file into private model space. Both show up in the ComfyUI loader nodes.

Can I import a workflow I found online?

Yes — drop the workflow JSON or a PNG carrying its metadata straight into the canvas. Because the common packs are already installed, most graphs run as-is.

Does my workflow persist between sessions?

Yes. Save workflows to your account and reopen them from any device; outputs land in your gallery rather than a local folder.

How is this different from running ComfyUI locally?

The software is identical — it is the same open-source ComfyUI. What differs is everything around it: the node packs, the 70,000+ models, the GPU and the version upkeep are ours to maintain instead of yours.

ComfyUI is included with the Pro plan and available on Basic and Plus as a $10/month bundle. Every plan is credit-based, so you can see what a run costs before queuing it.

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.
