AUTOMATIC1111 Review 2026 — Original Stable Diffusion WebUI
AUTOMATIC1111 is the original Stable Diffusion WebUI with 140K+ GitHub stars. Easy form-based interface with ControlNet, hundreds of extensions, and massive community support.
AUTOMATIC1111 Stable Diffusion web UI runs locally and provides browser-based controls for Stable Diffusion image generation. It supports text-to-image, image-to-image, inpainting, outpainting, upscaling, prompt weighting, LoRAs, embeddings, training tools, and an API.
It is used by artists, developers, researchers, and hobbyists who want local control over models and workflows. The software is free and open source, but users provide their own computer, compatible hardware, Python and Git setup, models, and any optional online GPU or hosting costs.
