FAQ about ComfyUI

QWhat is ComfyUI?

An open-source, node-driven visual workspace for building, saving and re-using diffusion-based image and video generation pipelines.

QHow do I build a basic image-gen workflow?

Drag nodes onto the canvas, connect data sockets, pick a model and prompt, then save or export the workflow as JSON for one-click reuse.

QCan I add my own nodes or extensions?

Yes—write or install custom nodes to integrate new models, tools or sub-pipelines and package them as reusable components.

QDo I need to code?

Core usage is 100 % visual; no coding required. Writing custom nodes needs basic Python if you want to go deeper.

QIs ComfyUI free? What does Comfy Cloud cost?

The app is open-source and free. Comfy Cloud is a separate hosted service—check the official site for current pricing and quotas.

QWhat hardware is required for local install?

Runs on Windows, macOS or Linux with CPU fallback and low-VRAM modes; speed scales with your GPU memory and core count.

QWhere can I find templates and sample workflows?

Open Comfy Hub inside the app or visit the community repo to browse, download and one-click-load trending workflows.

QHow does ComfyUI handle privacy?

Local runs keep all data on your machine; when you use cloud nodes or Comfy Cloud, refer to the respective provider’s privacy policy.
