Stable Diffusion WebUI Forge
A fork of the AUTOMATIC1111 web UI focused on performance and lower memory use, with a reworked backend that runs the same workflows faster and fits larger models into less VRAM. It keeps broad compatibility with A1111 extensions and layouts, so most existing guides still apply, while removing much of the slowness.
Strengths
- Optimised resource management and faster inference than base A1111
- One-click install packages, with FLUX and quantisation support
- Bundles ControlNet, LoRA, and IP-Adapter
Weaknesses
- Some features are unimplemented or broken
- Documentation is under construction and the UI changes
- CUDA-centric, so non-NVIDIA support is unclear
