Stable Diffusion UI

The easiest way to install and use Stable Diffusion on your own computer. Does not require technical knowledge, does not require pre-installed software. 1-click install, powerful features, friendly community.

(for support, and development discussion) | Troubleshooting guide for common problems

---

Step 1: Download and prepare the installer

Click the download button for your operating system:

On Windows:

1. Unzip/extract the folder stable-diffusion-ui which should be in your downloads folder, unless you changed your default downloads destination.
2. Move the stable-diffusion-ui folder to your C: drive (or any other drive like D:, at the top root level). C:\stable-diffusion-ui or D:\stable-diffusion-ui as examples. This will avoid a common problem with Windows (file path length limits).

On Linux:

1. Unzip/extract the folder stable-diffusion-ui which should be in your downloads folder, unless you changed your default downloads destination.
2. Open a terminal window, and navigate to the stable-diffusion-ui directory.

Step 2: Run the program

On Windows:

Double-click Start Stable Diffusion UI.cmd. If Windows SmartScreen prevents you from running the program click More info and then Run anyway.

On Linux:

Run ./start.sh (or bash start.sh) in a terminal.

The installer will take care of whatever is needed. If you face any problems, you can join the friendly Discord community and ask for assistance.

Step 3: There is no Step 3. It's that simple!

To Uninstall: Just delete the stable-diffusion-ui folder to uninstall all the downloaded packages.
