Getting a "can't verify the developer" warning?
If you see a warning on first launch, go to System Settings > Privacy & Security and click "Open Anyway". Open source software usually isn't signed with an Apple developer certificate, which is normal.
Clicking "Download" takes you to a source confirmation page first; the download starts after confirmation.

Risk notice
The executable uses a separate EULA (not pure AGPL-3.0), and this tool downloads and runs third-party packages and models. Please verify relevant licenses and content compliance before use. The README also warns about impersonation accounts; official information only comes from lykos.ai or the Discord server.
Who it's for
- Users who want to simplify installing and updating Stable Diffusion WebUI
- Creators who need to switch between multiple WebUI distributions
- Stable Diffusion users who want to manage models and checkpoints in one place
- Windows/macOS users who prefer portable applications
- Users who need to import models from CivitAI and HuggingFace
Who it's not for
- Users who don't need a package manager and just want to use a specific WebUI directly
- Users who require official Linux support (the official support list only includes macOS and Windows)
- Open-source purists who are unwilling to accept the separate EULA for the executable
- Users who want minimal software footprint or dependency management
Install guide
Windows (x64)
- Download
StabilityMatrix-win-x64.zip(recommended on this site), extract it, and runStabilityMatrix.exefrom the extracted folder. - It is recommended to keep the entire folder in a dedicated directory so the data directory moves with the software.
macOS (Apple Silicon)
- Download
StabilityMatrix-macos-arm64.dmg(recommended on this site), open it, and drag StabilityMatrix into the "Applications" folder. - On first launch, if the system warns that the app cannot be opened because it is from an unidentified developer, go to "System Settings" → "Privacy & Security", click "Open Anyway"; or right-click the app icon and select "Open".
Linux (x64)
- Download
StabilityMatrix-linux-x64.zip, extract it, and run the executable (you may need to runchmod +x <filename>first). - Note: The officially supported platforms are macOS and Windows. Evaluate the Linux package at your own discretion.
On first launch, the app will guide you to choose a data directory and may need to download dependencies (bundled Git and Python, no prior global installation required). You can then install and update WebUI packages through the app's package manager.
