ComfyUI

by Comfy-Org

ComfyUI is a visual, node-based program for generating images, video, audio and 3D models with AI models that run on your own computer. It is for building and reusing creative workflows with fine control, and it also offers an API so they can be used inside other applications.

Worth a lookEstablished, with a few things to check (listed below).

What you can do with it

  • Generate and edit images, including inpainting, outpainting and upscaling, using a drag-and-drop node graph
  • Create AI video, audio and 3D models from ready-made workflow templates
  • Save workflows as JSON and call them through the API from your own apps or production pipelines

Make money with it

Offer custom AI image, video or product-photo production to clients, or sell the finished artwork and the workflows you build.

An idea, not financial advice. Check the licence before charging for anything built on it.

Ways a business could use it

  • Produce product images, marketing visuals and short videos in-house instead of paying for stock images or per-image generation services
  • Build repeatable image or video workflows for clients and run them automatically through the API

Can you use it commercially?

Free to use. Anything you distribute that includes it must be open-sourced under the same licence.

Not legal advice. Read the project's licence file before building a product on it.

Getting it running

Install the Windows or macOS desktop application, or use the portable or manual install on Windows, Linux and macOS, then download the model files you want.

Follow the official instructions in the project README.

Things to check

  • GPL-3.0 licence, which has obligations if you distribute modified versions
  • Needs a reasonably capable GPU; the README says as little as 4GB VRAM can work but speed will vary
  • Optional partner/API nodes for closed models are paid
  • Model files have their own licences, so check them before commercial use
  • Third-party custom nodes are unvetted and carry a security risk

Who's talking about it

Hidden gem

pngdeer is a lossy PNG compressor that chooses the quality for each image itself, so there is no quality slider to set. It makes PNG files smaller while keeping them looking the same, and runs from the command line or in a web browser.
