Stable Diffusion WebUI

The classic open-source interface for Stable Diffusion.

AUTOMATIC1111's WebUI is the long-running open-source front end for Stable Diffusion image generation, with an enormous extension ecosystem — ControlNet, LoRAs, upscalers, and more. Power users love it; the setup and UI density are not beginner-friendly.
