Stability Matrix: Package manager for Stable Diffusion
Multi-backend inference UI manager with embedded dependencies.
Learn more about StabilityMatrix
Stability Matrix is a desktop application built with Avalonia and .NET that functions as a package manager for Stable Diffusion distributions and related machine learning tools. It handles dependency management, including embedded Git and Python runtimes, eliminating the need for separate system installations. The application supports multiple backend implementations including Automatic1111, ComfyUI, Forge, InvokeAI, and others, with plugin and extension management capabilities for compatible packages. Common deployment scenarios include local AI image generation workflows, model training interfaces, and inference UI management across different hardware configurations.
Multi-backend support
Manages installation and updates for 20+ different Stable Diffusion implementations and related tools through a single interface, rather than requiring separate manual setup for each package.
Embedded runtime dependencies
Includes bundled Git and Python environments, eliminating the need for users to install and configure these dependencies separately on their systems.
.NET desktop application
Built with Avalonia framework for cross-platform desktop deployment on Windows, Linux, and macOS, providing native application performance rather than web-based or Electron-based alternatives.

- –Upgrade nunchaku installer to 1.0.2 and use the new Python version selector in Package Import dialog.
- –Verify SwarmUI now launches correctly if previously blocked by dotnet dependency and check sageattention version after torch updates.
Fixes ComfyUI-Zluda cuDNN startup error, Civitai API 401 auth failures, and threading crashes in Python package search and image gallery.
- –Update InvokeAI rocm index to 6.3 and note SwarmUI now launches via script for compatibility.
- –Patch install failures when moving duplicate files to shared model folders and resolve threading issues in UI dialogs.
Fixes ComfyUI Inference connection breakage after recent ComfyUI updates and corrects FramePack triton install on Linux/macOS.
- –Update if ComfyUI Inference fails to connect after upgrading ComfyUI; missing API node dependencies are now included.
- –Non-Windows users installing FramePack will now receive the correct triton version; UI resize crash on model details is resolved.
