Stable Diffusion

Open-source AI image generator with unlimited customization

From $0/mo 0

About Stable Diffusion

Stable Diffusion is the most flexible AI image generator—fully open-source, endlessly customizable, and free if you self-host. Unlike Midjourney ($10-96/month) or DALL-E 3 ($20/month via ChatGPT Plus), Stable Diffusion gives technical users complete control: train custom models, fine-tune styles, run locally with no usage limits. Cloud services like Replicate start at $0.002/image, while serious users self-host on RTX 4090 GPUs ($1,600+). The modular ecosystem supports community innovations like ControlNet for pose control, IP-Adapter for character consistency, and LoRA models for specific styles. Perfect for product visuals, concept art, and ad campaigns—but requires technical skills. For quick quality with zero setup, choose Midjourney; for customization and cost efficiency at scale, Stable Diffusion wins.
