The limitation that matters
Check the exact model: SD3.5 uses the Community License, while other versions may have different terms. No universal output-rights or watermark claim applies across the family.
Stable Diffusion is a model family, not one free web app. ComfyUI can run offline and save generated images. Model files, compatible compute, memory, storage, and electricity are required. Hosted services and optional paid API nodes have separate charges.
