[About “ComfyUI”]
“ComfyUI” is a visual GUI (*4) tool that allows users to easily operate “Stable Diffusion.” It features an interface where each function required for image generation is represented as a block called a “node,” and these blocks are visually arranged and connected with lines. This makes it possible to organize complex image generation processes visually and execute settings and generation intuitively.
Normally, using “ComfyUI” requires downloading it from GitHub (*5) to your own PC and performing installation and setup. However, with “ConoHa AI Canvas,” it can be used easily through a web browser without any installation.

[Background of Providing “ComfyUI”]
Since its release on August 1, 2024, “ConoHa AI Canvas” has adopted “AUTOMATIC1111” (*6) as its WebUI, providing an environment where anyone can easily enjoy image generation without installation, using only a web browser. On the other hand, the use of “ComfyUI” has been rapidly expanding due to its quick support for the latest technologies and its ability to easily share settings. In response to these needs, “ConoHa AI Canvas” now supports “ComfyUI” in addition to “AUTOMATIC1111,” allowing users—from beginners to advanced users—to choose the most suitable WebUI and enjoy a more convenient AI image generation experience.
