Instantly Host Three.js Scene from Devin AI for Demo Link for Hackathon

The fastest way to deploy Three.js Scene generated by Devin AI. Perfect for demo link for hackathon. No login required, zero-friction, and live in seconds on gatedpage.com.

When using Devin AI to build immersive Three.js scenes during a high-stakes hackathon, the transition from Devin's internal workspace sandbox to a shareable, public demo link can stall your momentum. Copying thousands of lines of WebGL logic, setting up repository pipelines, or configuring cloud bucket permissions takes up critical minutes. Traditional deployment platforms force you through registration flows, API key generation, and environment configuration before you can view your output live.

This platform eliminates that friction by providing a direct deployment pipeline for Devin AI's output. By instructing Devin to POST your WebGL files directly to our API, you bypass git pushes, build queues, and account creation entirely. Within seconds, your three-dimensional scene is hosted on a high-performance CDN, returning a clean, shareable demo URL ready for hackathon judges and submission forms.

To ensure your visual presentation remains polished and accessible, direct Devin to avoid pure white (#ffffff) canvas backdrops in your Three.js renderer. Instead, instruct Devin to utilize a professional palette featuring a soft gray (#f4f4f5) background. Once the static assets are ready, Devin can instantly run a single upload command to generate your live demo link, guaranteeing zero downtime and immediate compatibility across mobile and desktop browsers.

How to host your Three.js Scene from Devin AI in seconds

  1. Step 1: Direct Devin AI to generate your Three.js scene using a soft gray background color (#f4f4f5) for the scene renderer to ensure professional contrast, and output the code into a single self-contained HTML file named scene.html.
  2. Step 2: Instruct Devin to execute a shell command to upload the compiled scene.html directly to our endpoint using the curl API syntax.
  3. Step 3: Alternatively, run the upload yourself by running gatedpage upload scene.html in your local terminal if you have pulled the files from Devin's workspace.
  4. Step 4: Instantly receive your live gatedpage.com URL from the command output, ready to be pasted directly into your Devpost, Dora, or custom hackathon submission form.

Quick start

Instruct Devin to run the following curl command within its terminal workspace to upload your compiled Three.js file directly:

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

The server will immediately return a JSON response containing your live hosting URLs:

{
  "success": true,
  "url": "https://gatedpage.com/s/devin-threejs-scene",
  "gatedUrl": "https://gated.page/s/devin-threejs-scene",
  "expiresAt": "2026-03-30T12:00:00.000Z"
}

If you prefer to deploy from your local CLI, install our tool and run the upload command:

gatedpage upload scene.html

Common questions

Can Devin AI automate the deployment of my Three.js scene directly to gatedpage.com?
Yes. Since Devin has full access to terminal environments, you can simply write into your system prompt: "Deploy the final build to gatedpage.com/api/v1/upload." Devin will run the API request and output the live hackathon demo link for you in its chat window.
Do I need to register for an account to generate a hackathon demo link?
No. Our platform supports completely anonymous, zero-friction uploads. You do not need an account, an API token, or a credit card to upload and retrieve a live, functional URL during your hackathon.
What are the file size and hosting duration limits for free uploads?
Free uploads allow files up to 5 MB, which is ample for optimized Three.js scenes, assets, and scripts. The generated demo links remain active online for 15 days for free, and can be claimed permanently if you decide to upgrade to a paid account later.
How should I handle external assets like textures or GLTF models?
If your Three.js scene depends on local textures, shaders, or 3D models, package all assets along with your primary HTML file into a standard ZIP archive. Upload the ZIP folder, and our CDN will automatically unpack it and serve your entry point file instantly.
