Our editorial review
MO
Stable Diffusion is less a single product than the open foundation much of the AI-image world is built on. If you have a GPU, it's free, private and endlessly customizable.
The trade-off is effort: self-hosting and prompt craft have a learning curve, and turnkey tools are more polished. Hosted options remove the setup at a per-credit cost.
Worth it for technical creators who value control, privacy and zero subscription lock-in.
