Should I use ComfyUI or the SD WebUI?

Choose ComfyUI for maximum control and repeatable, complex pipelines; choose the WebUI for a simpler, faster start.

What hardware do I need for ComfyUI?

A GPU with 8GB VRAM handles SDXL-class models comfortably; 12-24GB opens up video workflows and the largest checkpoints. Low-VRAM mode runs on less at reduced speed, and cloud GPUs are a solid fallback.

How do I install missing custom nodes?

Use the ComfyUI Manager: open it from the interface and install missing nodes in one click, or clone the node repository into ComfyUI/custom_nodes and restart. The manager also updates nodes and resolves dependencies.

This page is the ComfyUI product; workflow how-tos are on the ComfyUI Workflow Guide. A node-based, visual workflow interface for image generation models like Stable Diffusion and SDXL. It gives you fine-grained control over every step of the pipeline — from sampling to decoding — and lets you save, share and reuse workflows as files. Best suited for power users who need maximum flexibility and reproducible, complex image generation pipelines.

Our Verdict

ComfyUI is the power tool of image generation: node graphs expose every pipeline step, workflows are portable JSON files, and the community graph library covers everything from ControlNet stacks to video. The learning curve is real — expect a day of confusion before things click — but no other interface offers this much reproducible control. Creators who outgrow one-button generators eventually end up here.
