Stable Diffusion lets you generate images locally without subscriptions or limits. Here's what you need to know about hardware, setup, and licensing.

Stable Diffusion is a family of open models for image generation that you can download and run on your own computer. That’s what sets it apart from popular browser-based generators: no subscription, no limits, and no terms of service deciding what you’re allowed to create. In exchange, you need the hardware and the willingness to configure it - which isn’t difficult, but it’s not one-click either.
Why People Choose Local Image Generation
Control. You can steer the process far more precisely than with text descriptions: impose composition with a sketch, force character poses, repeat the same style across hundreds of images. This is why professionals stick with this solution despite the convenience of competitors.
Your own style. You can fine-tune the model on your own materials and get a generator that draws your character or your aesthetic. With closed tools, this feature is either unavailable or heavily restricted.
No per-image costs. Once you’re running, you generate as much as you want, which changes the economics of projects that require serial work and many iterations.
What Stable Diffusion Requires
A graphics card with adequate memory, patience during initial setup, and readiness for the fact that the ecosystem is fragmented: interfaces, add-ons, and models come from many creators and don’t always fit together. This is the real price of the freedom this solution offers, and the main reason most people stick with browser-based generators.
Licensing is a separate matter. Open doesn’t mean “do whatever you want” here: successive versions of the models had different terms, including commercial use restrictions depending on the scale of your business. Before using it for paid work, you need to check the terms of the specific version, not assume that because you downloaded it, you’re allowed.

If you need an image once in a while, all this configuration is a waste of time. For working with existing photos, a generator built into graphics software will be more convenient, as described in the guide to Adobe Firefly. For serial work without your own hardware, there’s Leonardo, and for quick materials Canva. A comparison of the entire category for specific tasks is collected in the article about AI image generators.
