Verdict:Stable Diffusion is free to download and run under the Stability AI Community License for individuals and organisations earning under USD 1 million a year, and above that Stability says to buy an Enterprise License at custom pricing. If it is not working for you, the reason is usually hardware or setup time rather than cost. Every alternative here is hosted, which removes the GPU requirement but also removes local control, fine-tuning on your own files and unlimited runs. Leonardo, Adobe Firefly and Ideogram all have free plans with daily or weekly allowances. Leonardo's vendor pricing page was blocked for us, and third-party reviews report 150 tokens a day, so check the number first. Firefly does not publish its free daily count. Ideogram's docs list 10 slow credits a week, up to 40 images. Gemini's free plan includes image generation and editing with a limit that refreshes every five hours, which suits occasional use. Midjourney has no free trial on the website, so it only makes sense if you will pay. The trade-off is simple: you give up ownership of the pipeline and the ability to run offline. If you generate a lot of images, stay with Stable Diffusion and fix the setup. If you generate a few per week, a free hosted plan is faster.

Why people look for Stable Diffusion alternatives
Stable Diffusion's core models are free under Stability's Community License only for organisations with less than $1M in annual revenue; above that an Enterprise License with custom pricing is required. Researchers using the models for commercial purposes must register with Stability AI. The licence can be revoked if its terms are broken, and it bars using the models, their derivatives or outputs to create a competing foundational model, although LoRAs, hypernetworks and fine-tunes are allowed.
