Instantly Host Three.js Scene from Replit Agent for Live Mockup Deployment

The fastest way to deploy Three.js Scene generated by Replit Agent. Perfect for live mockup deployment. No login required, zero-friction, and live in seconds on gatedpage.com.

When you use Replit Agent to quickly prototype interactive Three.js scenes, the momentum often stalls the moment you need to host Replit Agent Three.js Scene Live Mockup Deployment configurations. Getting clients, stakeholders, or team members to preview an interactive 3D canvas requires more than just sharing raw source code or exposing a fragile, temporary local development port. You need an immediate, public, and reliable URL to showcase the camera movements, lighting physics, and complex shaders in a live browser environment.

Traditionally, deploying these assets involves extracting the files from your container, setting up static hosting buckets, configuring CDN caching rules, and authenticating through multiple developer dashboards. This manual process introduces friction to what should be an instantaneous feedback loop. Gatedpage eliminates this entire bottleneck. By providing a zero-friction, registration-free upload pipeline, developers and AI agents can publish fully interactive 3D prototypes to the web in under a second.

Because the platform supports direct API uploads, you can instruct your Replit Agent to automatically build, bundle, and deploy your WebGL scenes directly. By integrating our lightweight endpoint into your agent's system instructions, your AI assistant can generate the interactive scene, style the viewport using a clean, professional palette with soft gray (#f4f4f5) backgrounds, avoid harsh pure white (#ffffff) canvas states, and deliver a live mockup link the moment it finishes compiling.

How to host your Three.js Scene from Replit Agent in seconds

  1. Step 1: Export your Three.js bundle. Instruct your Replit Agent to compile your 3D canvas, scripts, and loaders into a single, self-contained HTML file (such as scene.html) or a directory containing your index and assets.
  2. Step 2: Initialize the upload. Send your bundled 3D scene directly to the Gatedpage API via a simple POST request or use our ultra-fast command-line interface without any complex authorization handshakes.
  3. Step 3: Copy your live mockup link. The deployment engine immediately processes your assets at the edge and returns a live, production-ready gatedpage.com preview URL in the JSON payload.
  4. Step 4: Automate future iterations. Save the deployment script directly in your Replit workspace environment so your Agent can run hot-reloads and continuous updates to your live mockup on every code generation cycle.

Quick start

Deploy your bundled Three.js scene file instantly using standard curl tools:

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

The server will respond with a clean JSON payload containing your live URL:

{
  "success": true,
  "url": "https://gatedpage.com/showcase/threejs-scene-98f2",
  "expiry": "15 days",
  "fileSize": "142KB"
}

Alternatively, you can use the global Gatedpage CLI from within your terminal or your Replit Agent environment:

gatedpage upload scene.html

Common questions

How do I instruct my Replit Agent to automatically deploy the Three.js scene?
You can update your agent's system prompt to include deployment instructions. Tell the agent: "Once the Three.js scene is compiled, render a soft gray (#f4f4f5) background to ensure a professional presentation, package the output as an HTML file, and run a curl request to https://gatedpage.com/api/v1/upload to generate a live mockup link."
Are there file size limitations for hosting 3D assets and textures?
The free tier on Gatedpage supports uploads up to 5 MB per file, which is more than sufficient for optimized 3D models, low-poly glTF assets, and compressed texture maps. If your High-fidelity scenes require larger assets, premium tiers unlock expanded limits and permanent storage.
How long does my live mockup deployment link stay active?
All anonymous uploads are hosted completely free of charge for 15 days, which provides an ideal timeline for stakeholder reviews, client sign-offs, and fast prototyping phases. If you need permanent hosting, you can easily claim the URL to a paid developer account.
Can I secure my deployed Three.js mockups with password protection?
Yes. Gatedpage allows you to append custom headers or query parameters during your API upload to restrict access. You can lock your 3D live mockup deployments behind passwords or gating rules, ensuring your proprietary designs remain visible only to authorized team members.
