How ComfyUI compares to SwarmUI
SwarmUI wraps ComfyUI as its execution backend; running ComfyUI directly gives lighter installation and direct access to every custom node.
**Where ComfyUI pulls ahead:** Zero wrapper overhead, direct custom_nodes debugging, and native Windows desktop installer.
**Where SwarmUI fits:** Built-in parameter grid generator and simplified Generate tab on top of a Comfy backend.
Running both tools on the same Windows PC without duplicating checkpoints
You do not need to delete SwarmUI or duplicate 100 GB of `.safetensors` files to switch to ComfyUI. Configure extra_model_paths.yaml so ComfyUI reads your existing checkpoints, LoRAs, VAEs, and ControlNets directly from disk.
Install the Windows desktop or portable build from /download and point it at your existing model library in under two minutes.
ComfyUI vs SwarmUI Feature Matrix
| Capability | ComfyUI (Windows) | SwarmUI |
|---|---|---|
| Execution engine | Native ComfyUI core | Spawns ComfyUI backend worker |
| Custom node compatibility | 100% direct | Requires Raw Comfy workflow tab |
| Windows installer footprint | Single desktop or portable folder | .NET + Comfy backend stack |
| Graph editing | Primary workspace | Secondary tab |
FAQs
Can ComfyUI and SwarmUI share the same models folder on Windows?
Yes. Edit `extra_model_paths.yaml` in your ComfyUI root folder to point `base_path` at your existing models directory so both apps load the exact same files.
Does ComfyUI use less VRAM than SwarmUI?
ComfyUI only keeps the active node's sub-model (CLIP, UNet, or VAE) in VRAM at each step and supports native FP8 and GGUF quantization, making it significantly lighter on 8 GB and 12 GB GPUs.
