HappyDiffusion for Web

Quick snapshot

HappyDiffusion is a browser-based image-generation service built on top of the Stable Diffusion family. It’s delivered as a subscription product with a simple setup process, and it runs on both smartphones and desktop computers so you can create visuals from almost anywhere.

• Designed to accommodate both casual experimentation and advanced workflows that require specialty or niche model files.
