Stable Diffusion is the open-source AI image generation model that powers most NSFW AI tools behind the scenes. While cloud platforms like SoulGen and Promptchan are more convenient, running Stable Diffusion locally gives you complete control: no content filters, no usage limits, no subscription fees, and total privacy.
This guide covers everything you need to get NSFW Stable Diffusion running on your own computer in 2026.

Choosing a WebUI
You need a user interface to interact with Stable Diffusion. The three main options:
Automatic1111 (A1111)
The most popular and feature-rich WebUI. Supports every extension, model, and workflow you can think of. Best for users who want maximum control and don't mind a busier interface.
ComfyUI
A node-based workflow editor that's more complex but incredibly powerful. Best for advanced users who want to create custom generation pipelines. Growing rapidly in popularity.
Fooocus
Simplified interface inspired by Midjourney. Less control than A1111 or ComfyUI but produces excellent results with minimal effort. Best for beginners or those who just want good output quickly.
