What ComfyUI does that other tools do not
ComfyUI exposes the full Stable Diffusion graph as connectable nodes. You can chain prompts, masks, control nets, image to image passes, and upscalers in a single workflow. For marketing teams that means repeatable creative pipelines. One brand consistent template generates a full ad set when fed a product photo and a copy variant.
How to install ComfyUI on macOS
Install Python and Git
Use Homebrew.
brew install python@3.11 git is enough for an M1 or M2 Mac.Clone the repo
git clone https://github.com/comfyanonymous/ComfyUI.git
cd ComfyUI
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txtDownload a base model
Drop an SDXL base model into models/checkpoints/. The official Stable Diffusion XL release is around 6.5 GB. For brand consistent product photography start with Juggernaut XL or RealVisXL.
Run ComfyUI
python main.pyOpen localhost port 8188 in a browser. The default graph is loaded.
How to install ComfyUI on Windows
Use the prebuilt portable Windows release from the GitHub releases page. Unzip, run run_nvidia_gpu.bat if you have an NVIDIA card, orrun_cpu.bat if you do not. NVIDIA is roughly 50 to 200 times faster than CPU on image generation.
Cloud deploy for shared team access
For shared team use, deploy ComfyUI to RunPod or Vast.ai. Pick an A100 or A10G instance. The community ComfyUI Docker image starts in two minutes. Expose the web UI through a reverse proxy with auth so only your team can access it.
Five marketing workflows that pay back the install
- Product on white to lifestyle background swap with masking nodes.
- Ad creative variant batch from one hero image plus six copy variants.
- Color palette enforcement across a campaign using IP Adapter.
- Founder photo to brand consistent thumbnail series.
- Localized creative for SEA markets without re shooting.
Quick answers
- Do I need a GPU to run ComfyUI?
- Strongly recommended. CPU works but is 50 to 200 times slower. An NVIDIA card with 8 GB VRAM minimum, 12 to 24 GB ideal. M1 and M2 Macs work but are slower than a desktop NVIDIA setup.
- Is ComfyUI free?
- Yes. ComfyUI is open source. The base Stable Diffusion models are also free. Some premium fine tuned models require a license fee.
- ComfyUI vs Midjourney for marketing
- Midjourney is faster to first image and produces more cinematic output by default. ComfyUI gives reproducibility, batching, and control net workflows that Midjourney does not. Most agencies use both.
- Can ComfyUI run on a Mac with Apple Silicon?
- Yes. Recent versions support MPS acceleration on M1 and M2. Generation times are slower than NVIDIA but acceptable for development work.
- Is the output commercially usable?
- It depends on the model license. Stable Diffusion XL base is permissive for commercial use. Some community fine tunes restrict commercial use. Always check the model license before shipping creative.
