ComfyUI - A modular, optimized GUI for stable diffusion

ComfyUI is a versatile and robust graphical user interface (GUI) designed for stable diffusion. With its easy-to-use graph/nodes interface, users can create and execute advanced stable diffusion pipelines using a flowchart-based approach. ComfyUI supports both SD1.x and SD2.x and offers various optimizations, such as re-execution of only the parts of the workflow that have changed between executions. Additionally, the platform supports loading of checkpoints and safetensors models, as well as various upscaling models such as ESRGAN, ESRGAN variants, SwinIR, Swin2SR, among others. ComfyUI also offers the capability to save and load workflows as JSON files, and generate and load full workflows from PNG files. Overall, ComfyUI is a powerful tool for stable diffusion that offers a range of features to simplify the process of designing and executing workflows.
