// how it works
How it works
- Install the desktop app
The official desktop app for Windows and Mac is the recommended start. A portable Windows build and manual installs exist for tinkerers.
- Add your models
Place checkpoint files in models/checkpoints and VAEs in models/vae — ComfyUI works with the open models you bring.
- Build a workflow
Drag nodes onto the canvas: a loader, a prompt, a sampler, a saver. Connect them into a pipeline you can see and tweak.
- Queue and iterate
Hit queue, watch each node execute, and save the workflow as a reusable template or share it as JSON.
// features
Why people love it
Node-graph control
Every parameter is explicit and adjustable — no hidden settings, total reproducibility.
Blazing local inference
Built for speed on your own GPU, with support for the latest open diffusion models.
GUI + API + backend
Use it visually, drive it from code, or embed the engine in your own product.
Massive node ecosystem
Thousands of community custom nodes add video, 3D, upscaling, and exotic samplers.
Beyond images
The same graph approach now covers video generation, 3D models, and audio.
Shareable workflows
Entire pipelines save as portable files — download someone's workflow and run it as-is.

// run it
Run it yourself
- Step 1 — Get the desktop app
Download it from comfy.org/download — the easiest path for new users on Windows or Mac.
- Step 2 — Or go portable (Windows)
Download the portable .7z, extract it with 7-Zip, and run. Drop your checkpoint files into ComfyUI\models\checkpoints.
- Step 3 — Or install manually
Clone the repo, install PyTorch, and launch. AMD GPUs on Linux can use the ROCm PyTorch build.
git clone https://github.com/Comfy-Org/ComfyUI.git cd ComfyUI pip install torch torchvision torchaudio --upgrade
// use cases
What you can build
- Production art pipelines with exact, repeatable settings.
- Character-consistent series via reusable workflows.
- Upscaling and restoration chains for old media.
- API-driven generation inside your own apps.

Questions, answered
Is ComfyUI free?
Yes — it is GPL-3.0 licensed and free to use. Keep the GPL terms in mind if you distribute modified versions.
Is it beginner friendly?
The desktop app smooths installation, but the node interface has a real learning curve. Templates and community workflows help a lot.
ComfyUI or InvokeAI?
ComfyUI gives maximum control through its node graph; InvokeAI offers a more polished, canvas-style experience. Many artists use both.
Which models does it run?
It is model-agnostic — you supply checkpoints (Stable Diffusion family, Flux, Wan, and more) and it runs them.
Can I use it commercially?
GPL-3.0 allows commercial use; the main obligations kick in around distributing modified code. Read the license for details.
