What is midjourney-comfyui?

Midjourney ComfyUI Nodes lets you use Midjourney's image generation directly inside ComfyUI, a popular visual tool for building AI image workflows. Normally, Midjourney is a separate service with its own interface, but this project bridges the gap so you can generate Midjourney images alongside other AI tools without jumping between different apps. Each generation gives you four images at once. ComfyUI works by connecting "nodes", little boxes that each do one job, with wires, forming a visual pipeline. This project adds Midjourney-specific nodes to that system. You enter a text prompt, pick settings like aspect ratio or stylization level, and the node sends your request to an API service called muapi.ai, which actually runs Midjourney behind the scenes. When the four images come back, they flow into whatever you've wired up next, a preview window, a file saver, an upscaler, and so on. You can also provide a reference image to guide the output style. This is aimed at people who already use ComfyUI and want to incorporate Midjourney's distinctive look into their workflows. For example, a game designer building concept art pipelines might want Midjourney's cinematic V8 output alongside other models, all controllable from one canvas. An illustrator working on anime-style projects could use the Niji node for character sketches, then pass those images into other nodes for upscaling or variation. The project supports three Midjourney versions: V7 and V8 for photorealistic or artistic results, and Niji for anime and manga styles. A few practical notes: you need a muapi.ai account and API key, since that service handles the actual Midjourney calls. The README notes that all three nodes share the same controls, prompt, aspect ratio, stylize, chaos, weird, negative prompt, seed, and optional reference image, so once you learn one, you know them all. The output is a batch of four images plus their URLs, which keeps things compatible with standard ComfyUI nodes for viewing or saving.
