FAQ

General

Can I use React or Vue instead of Solid?

Not out of the box. The official bridge runtime targets Solid today.

Does Loom work with IL2CPP?

Yes. Loom supports Mono and IL2CPP player builds on supported platforms.

Can I use Tailwind or other CSS frameworks?

Yes. Your UI is a Vite app, so CSS tooling works normally. See Adding npm packages.

Can I have multiple bridges?

Most games should use one root bridge. Route between HUD, pause, inventory, and menus with screen state inside that bridge.

Can I load external URLs?

No. Loom is a game UI framework for your bundled app, not a general-purpose web view for arbitrary sites.

Does Loom collect telemetry or project data?

No. Loom does not send telemetry, analytics, crash reports, project files, UI source, or bridge data to Snack Software. Initial UI setup downloads third-party dependencies from your configured npm registry. See Privacy and network access.

Does Loom support multiplayer networking?

Yes. Loom is just a UI layer, so you can reflect networked game state through bridge state the same way you reflect local game state.

Development

How do I see UI changes without pressing Play?

Use Mock mode to run the UI in a browser with mock bridge state and actions.

Where do console.log messages appear?

UI logs appear in browser DevTools. Open them with Tools > Loom > Open Browser DevTools.

Building and shipping

Do I need Node.js in my shipped game?

No. Node.js is only needed during development and on build machines. The shipped game loads static UI files from StreamingAssets/Loom.

Does the UI build run automatically?

Yes. Loom runs the UI production build during player builds. See Player builds.

Licensing

Is Loom free?

No. Loom is a commercial product. See Buy.

How is Loom licensed?

The Unity Asset Store edition is a perpetual single-seat license. All updates published to that Loom SKU are included. Studios can instead request a direct 12-month team license with support included. See Buy for the two options.
