# ComfyUI vs SwarmUI

SwarmUI wraps ComfyUI as its execution backend; running ComfyUI directly gives lighter installation and direct access to every custom node.

## Facts (2026-10-17)

- **Compared Against:** SwarmUI
- **ComfyUI Edge:** Lower VRAM, Flux/Video support, node graph
- **Shared Models:** Yes via extra_model_paths.yaml
- **Windows Build:** Free download at /download

## 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 |

## 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](https://comfy.ink/install/extra-model-paths-yaml-setup) so ComfyUI reads your existing checkpoints, LoRAs, VAEs, and ControlNets directly from disk.

Install the Windows desktop or portable build from [/download](https://comfy.ink/download) and point it at your existing model library in under two minutes.

## FAQ

### 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.
