WebUI vs ComfyUI
AUTOMATIC1111 Stable Diffusion WebUI (164,420 stars) is the easiest: one-click installer, huge extension ecosystem, best for beginners and quick generations. ComfyUI (comfyanonymous/ComfyUI, 124,185 stars) is the node-based power tool: visual workflows, precise control, faster for complex pipelines and batch jobs.
Hardware reality: 8GB VRAM runs SD 1.5 and SDXL comfortably; 12-16GB unlocks Flux-class models. CPU-only works for SD 1.5 at minutes-per-image - usable for experimentation, painful for production. Both support LoRA, ControlNet, and inpainting; both run completely offline once models are downloaded.
