Best free and opensource image generator with the ability to use templates and local installation.
Stable Diffusion is an AI-powered text-to-image generator developed by Stability AI in collaboration with CompVis and LAION. It takes text prompts (like “a futuristic city at sunset”) and turns them into detailed, high-quality images — all without needing the cloud.
It runs locally on your PC, in the cloud, or via web apps, and it’s completely open-source, making it perfect for developers and artists who want full control over their AI-generated art.
