Install Loom

Loom GUI is a UPM package. Asset Store customers install it from My Assets in Unity’s Package Manager; you do not need to copy files into Packages/ or edit manifest.json yourself.

The matching @loomgui/bridge and @loomgui/vite-plugin packages are bundled inside the Unity package. Initial UI setup still needs registry access for Solid, Vite, and their third-party dependencies unless your team provides them through a cache or registry mirror.

Before you start

Make sure your project matches Supported platforms:

• Unity 6000.3.0f1 or newer
• URP 17.3.0 or newer
• Node.js 22 or 24 LTS
• npm 10 or 11
• macOS Apple Silicon or Windows x86-64

Install from the Unity Asset Store

1. Open your project in Unity.
2. Open Window > Package Management > Package Manager.
3. Select My Assets and sign in with the Unity account that owns Loom GUI.
4. Find Loom GUI, select it, and click Install.
5. Wait for Unity to finish resolving packages and compiling scripts.

Import Getting Started

1. Keep Loom GUI selected in Package Manager.
2. Open its Samples tab.
3. Import Getting Started.
4. In the Project window, open the imported README.md and follow its short setup sequence.

The sample is intentionally small: one reactive C# property and one UI action. It verifies the complete Unity-to-Solid path before you add Loom to production code.
