Exporting as Self-Hosted Project

The Self-Hosted export option in Spline allows you to export your entire project, including all assets and the Spline runtime, as a fully self-contained ZIP file.

This is ideal for scenarios where you want full control over hosting, and do not wish to rely on external servers or CDN requests.

Key Features

• Fully Offline: No need for internet access after deployment.

• Includes Spline Runtime: Everything needed to render your scene is bundled.

• Custom Hosting: Deploy on your own server or preferred hosting service.

How to use

1. In the top toolbar, click the Export button.

2. Under the Web section, select Self-Hosted.

3. Choose your preferred code format: Vanilla JS, React, or Next.js.

4. Click Download Self hosted ZIP.

5. Unzip the downloaded file.

6. Upload the contents to your hosting server.

Export Modes

- Vanilla JavaScript

• Exports a ready-to-use HTML + JS bundle

• No extra setup needed — just unzip and upload to your server

• Easiest way to deploy standalone scenes

- React / Next.js

• Not prebuilt: designed to be used inside a larger React or Next.js project

• Requires npm install to fetch dependencies (like @splinetool/react-spline)

• All WASM and runtime assets are loaded locally via node_modules or the public/ directory

• Ideal for developers who want to self-host but still benefit from React/Next integration and tooling

Summary

• Use Vanilla JS if you want a zero-config, upload-and-go experience.

• Use React/Next.js if you’re integrating Spline into a full frontend project with your own hosting and build pipeline.

That’s it — your Spline scene will now run independently, without fetching any external dependencies.
