Midjourney vs Stable Diffusion (ComfyUI)
Overview
Midjourney is the market-leading AI image generator charging $10–$60/month for varying generation credits. Stable Diffusion is a free, open-source image generation model you can run locally with ComfyUI or Automatic1111 — generating unlimited images at no ongoing cost once hardware is set up.
Key Differences
- Cost: Midjourney charges monthly; Stable Diffusion is free after hardware investment
- Hardware: Stable Diffusion benefits from a GPU (8GB+ VRAM); Midjourney is cloud-based
- Image quality: Midjourney Niji/v6 leads aesthetics; Flux Dev/Schnell is competitive for photorealism
- Privacy: Local SD generates images never sent to any server; Midjourney stores all your generations
- Customization: SD supports LoRA models, ControlNet, inpainting, upscaling; Midjourney is guided prompting only
