How to Install SwarmUI
Windows
- Download
install-windows.batfrom the SwarmUI GitHub page into an empty folder. - Run it; it installs Git, .NET and SwarmUI.
- Follow the web installer: choose theme, backend (ComfyUI) and starter models.
Linux
sudo apt install -y git dotnet-sdk-8.0 python3-venv
git clone https://github.com/mcmonkeyprojects/SwarmUI
cd SwarmUI && ./launch-linux.shSee the SwarmUI GitHub README for the latest install notes for your Linux distribution.
Using Multiple GPUs
In Server → Backends you can add one ComfyUI backend per GPU, or remote backends on other servers. SwarmUI then spreads generations across them, which is great on a multi-GPU server such as GPU Mart’s 2× RTX 4090 or 4× RTX A6000.
Run SwarmUI in the Cloud
No powerful GPU at home? You can run SwarmUI on a rented GPU server instead. Rent an RTX 4090 on RunPod ($0.34/hour) and install SwarmUI with the Linux script. For a fixed monthly price, GPU Mart (RTX A4000 VPS from $119/month, RTX 4090 $409/month) and HOSTKEY (RTX 4090 from €279/month) offer dedicated servers you can keep running 24/7.
FAQ
Yes. StableSwarmUI was renamed SwarmUI and is now developed independently by mcmonkey.
It installs and manages ComfyUI as its backend automatically.
Conclusion
SwarmUI gives you ComfyUI power with a friendly UI and multi-GPU support. It is a great choice for image generation on a powerful GPU server.
