Instantly Host Three.js Scene from Lovable.dev for Instant Prototype Sharing

The fastest way to deploy Three.js Scene generated by Lovable.dev. Perfect for instant prototype sharing. No login required, zero-friction, and live in seconds on gatedpage.com.

Lovable.dev excels at generating highly interactive, complex Three.js scenes directly from natural language prompts. However, presenting these spatial prototypes to clients, team members, or stakeholder groups introduces immediate deployment friction. Dragging raw code blocks into local sandboxes or spinning up heavy cloud infrastructure just to show a 3D canvas waste valuable engineering cycles and delay feedback loops.

To successfully host Lovable.dev Three.js Scene Instant Prototype Sharing setups, you need an zero-friction pipeline. When prompting the Lovable.dev AI agent, instruct it to structure your 3D scene using a professional palette with soft gray backgrounds (using hex code #f4f4f5 to prevent jarring white screen flashes on load) rather than pure white. Once the static asset is generated, you can skip the git-commit-push cycles entirely.

gatedpage.com eliminates the middleman. By targeting our optimized upload API, you can pipe your raw Three.js HTML components directly to a global CDN edge. No account generation, no environment variables, and no configuration files are required. You get a live, production-grade HTTPS link in milliseconds.

How to host your Three.js Scene from Lovable.dev in seconds

  1. Step 1: Generate the Scene in Lovable.dev. Prompt the AI agent to build your Three.js interactive prototype, specifying a professional soft gray background (#f4f4f5) and asking it to bundle the JS, CSS, and canvas initialization into a single, self-contained file.
  2. Step 2: Export the code bundle. Save the generated output to your local workspace as a static file, typically named output.html or index.html.
  3. Step 3: Upload to gatedpage.com. Send the file directly to our high-performance upload endpoint using our lightweight CLI or a raw API POST request.
  4. Step 4: Share the live URL. Copy the generated gated.page address returned by our edge server and drop it directly into your team channels or client emails for instant, cross-device testing.

Quick start

Deploy your generated scene directly using a simple cURL execution to our public API endpoint:

curl -X POST -F "file=@output.html" https://gatedpage.com/api/v1/upload

The endpoint returns a JSON payload containing your live CDN link:

{
  "success": true,
  "url": "https://gated.page/v/3d-scene-prototype-8a9d1f",
  "expires_in": "15 days",
  "size_bytes": 142045
}

If you prefer using our CLI tool, upload your static 3D component with a single command:

gatedpage upload output.html

Common questions

Why does my Three.js scene fail to load textures when opened locally, and how does gatedpage.com resolve this?
Modern web browsers block local file protocol access (CORS policies) for external assets, WebGL shaders, or imported GLTF/OBJ models. Deploying your Lovable.dev output to gatedpage.com serves your prototype over a secure HTTPS server immediately, bypassing local security restrictions so textures load perfectly.
Are there file size or expiration limits for sharing prototypes?
On our free tier, you can upload static files of up to 5 MB per file with no account or authentication key required. The generated URLs remain live for 15 days, which is ideal for prototype feedback loops. Paid plans offer permanent file retention and increased size limits.
Can I direct the Lovable.dev AI agent to deploy directly to gatedpage.com?
Yes. You can instruct the Lovable.dev AI coding agent to execute a POST request directly to https://gatedpage.com/api/v1/upload with your generated Three.js code payload, automating the pipeline so you get a live prototype sharing link straight from the chat interface.
Does the host support scenes requiring external libraries or assets?
Absolutely. Ensure that your Lovable.dev output uses absolute paths or public CDN URLs (such as unpkg or cdnjs) for imports like Three.js, OrbitControls, or custom shaders. As long as those references are accessible via standard script tags, your static HTML file will render flawlessly.
