ComfyUI lets you create images, video, audio, and more by connecting steps on a canvas. A set of connected steps is called a workflow. You can begin with a ready-made template and change it later.

​
Choose where to run ComfyUI

Use Comfy Cloud

Open ComfyUI in a browser. No local installation or model download is needed to try a template.

Run on your computer

Install Comfy Desktop on Windows, macOS, or Linux. Your device runs local models you download.
Both paths use workflows and templates. If you use a Partner Node in either path, that node calls a hosted model and may require an account and credits. Compare the ways a workflow can run.

​
Your first three steps

  1. Create your first image with a template. You can follow the Cloud path first, or use your local installation.
  2. Understand the workflow you used. Learn what a template, node, model, and connection do.
  3. Try another template or follow a text-to-image tutorial to change more than the prompt.
If you opened a workflow from someone else and it will not run, start with Fix a workflow that will not run. It helps you identify missing models, missing nodes, inputs, and account or credit requirements.
