Stability Matrix
Multi-platform package manager for Stable Diffusion UIs.
About
Managing local Stable Diffusion installs is the job of Stability Matrix, a desktop application from Lykos AI that installs, updates, and launches more than 20 image generation packages including AUTOMATIC1111, Forge and reForge, ComfyUI, InvokeAI, Fooocus variants, SwarmUI, and trainers like Kohya's GUI and OneTrainer, each in one click. Git and Python dependencies are embedded, so nothing needs to be installed globally, and the whole setup stays portable across drives and machines. A unified checkpoint manager shares model files between all installed packages, avoiding duplicate multi-gigabyte downloads, and models can be browsed and imported directly from CivitAI and Hugging Face with automatic metadata lookup. The app also includes its own inference interface with prompt auto-completion, syntax highlighting, dockable panels, and project files that preserve generation metadata. It runs on Windows 10 and 11, Linux via AppImage or the Arch AUR, and Apple Silicon Macs. Source code is available under the AGPL 3.0 license, while official binaries ship under a proprietary EULA.
Should you use Stability Matrix?
Pick it when
Pick Stability Matrix when you run several image UIs or trainers side by side, say ComfyUI, Forge, and OneTrainer, and want them sharing one checkpoint folder with self-contained Python and Git instead of global installs.
Look elsewhere when
Skip it if you only ever use ComfyUI, where ComfyUI Manager handles nodes and models inside the app, or if you need open source binaries: official builds ship under a proprietary EULA, so you would build from the AGPL source.
Alternatives to Stability Matrix
- Pinokio
Broader catalog that includes LLM apps like Ollama under an MIT license, but it is a general app launcher rather than a model manager built for image UIs.
- ComfyUI Manager
Handles custom nodes, missing node resolution, and snapshots inside ComfyUI, deeper for that one app but no help with your other UIs.
- Civitai
Browse with full community reviews and example images on the site itself, but you download and organize model files by hand instead of importing them.
