SD.Next
Open-source all-in-one WebUI for AI image and video generation.
About
SD.Next is an open-source server application and web interface for generative image and video work, maintained by Vlad Mandic as a fork-line successor to the Automatic1111 WebUI. It supports dozens of models across Stable Diffusion, SDXL, SD3, Flux, and others, and goes beyond generation with captioning, upscaling, image processing, and video pipelines in one modern cross-platform app.
Where Automatic1111 development slowed, SD.Next kept moving: it absorbed newer model architectures and workflow features faster, which is why many power users migrated. It runs locally on Windows, Linux, and macOS with community-supported builds, and exposes the full parameter surface that researchers and artists expect from a desktop diffusion workbench.
