SD.Next

SD.Next is an open-source WebUI application for AI image and video generation, maintained by developer vladmandic on GitHub under the Apache License 2.0. It builds on the original Automatic1111 WebUI codebase and extends it with broad model support, cross-platform hardware compatibility, and unique performance features. The project is actively maintained, with the repository last pushed to in June 2026.

What It Is

SD.Next is a self-hosted, all-in-one web interface for running Stable Diffusion and other generative AI models locally. It targets artists, researchers, and AI enthusiasts who want a powerful, flexible image and video generation environment without relying on cloud services. Users install it on their own hardware and access it through a browser-based UI that works on both desktop and mobile.

Supported Models and Hardware

SD.Next supports a broad range of diffusion models documented in its model support pages. On the hardware side, it covers an unusually wide spectrum:

• NVIDIA GPUs via CUDA on Windows and Linux
• AMD GPUs via ROCm (Linux/Windows) and ZLUDA (Windows)
• Intel Arc GPUs via OneAPI/IPEX XPU on Windows and Linux
• Any CPU/GPU compatible with OpenVINO on Windows and Linux
• DirectX-compatible GPUs on Windows via DirectML
• Apple M1/M2 on macOS via PyTorch MPS
• ONNX/Olive runtime support
• Docker container recipes for CUDA, ROCm, Intel IPEX, and OpenVINO

Unique Technical Features

SD.Next ships several capabilities the README describes as not found in other WebUIs:

• SDNQ: A state-of-the-art quantization engine that supports pre-quantized models or on-the-fly quantization, claiming up to 4x VRAM reduction with minimal quality or performance impact
• Balanced Offload: Dynamically balances CPU and GPU memory to run larger models on limited hardware
• Captioning: Supports 150+ OpenCLIP models, WaifuDiffusion and DeepDanbooru taggers, and 25+ built-in VLMs
• Image Processing: A full color-grading and image correction suite built into the interface
• Localization into approximately 15 languages with support for multiple UI themes

Setup Path

SD.Next uses a built-in installer with automatic updates and dependency management. The quick-start path is a git clone followed by running webui.sh (Linux/Mac), webui.bat (Windows), or webui.ps1 (PowerShell). Platform-specific guides cover WSL, Intel Arc, DirectML, OpenVINO, ONNX/Olive, ZLUDA, AMD ROCm, macOS, NVIDIA, and Docker deployments. An install walkthrough video is linked from the README.

Project Status and Community
