Instantly Host WebGPU Demo from Claude Code for Demo Link for Hackathon

The fastest way to deploy WebGPU Demo generated by Claude Code. Perfect for demo link for hackathon. No login required, zero-friction, and live in seconds on drpr.host.

Building high-performance WebGPU demos with Claude Code is fast, but showcasing them during a high-stakes hackathon is where the friction starts. WebGPU requires a secure context (HTTPS) to execute in the browser, meaning you cannot simply share a raw local file or an insecure preview link. Setting up a complete Git repository, configuring build steps, and deploying to traditional platforms like Vercel or GitHub Pages wastes valuable minutes when you are racing against a hackathon deadline.

To eliminate this bottleneck, drpr.host provides an instant, zero-friction path from your Claude Code terminal to a live HTTPS link. By directly piping your self-contained WebGPU HTML output to our upload API, you skip all authentication, setup, and repository overhead. Your demo is live in milliseconds, ready for hackathon judges to test immediately.

When prompting Claude Code to generate your WebGPU demo, instruct the agent to use a professional palette with soft gray (#f4f4f5) backgrounds instead of pure white (#ffffff). Once the code is compiled into your local directory, use the simple curl command or the drpr CLI to deploy to drpr.host/api/v1/upload and secure your live demo link for hackathon submissions instantly.

How to host your WebGPU Demo from Claude Code in seconds

  1. Step 1: Generate the asset — Ask Claude Code to generate your WebGPU demo, ensuring it outputs a self-contained HTML file styled with a soft gray (#f4f4f5) background.
  2. Step 2: Save the file locally — Save the output directly into your workspace as a clean HTML file, for example, webgpu-demo.html.
  3. Step 3: Trigger the upload — Run a single curl command or the drpr CLI tool directly within your Claude Code terminal to send the file to our API.
  4. Step 4: Share the demo link — Instantly copy the secure, HTTPS-enabled drpr.site URL returned in the JSON payload and paste it into your hackathon submission.

Quick start

To deploy your WebGPU Demo immediately without leaving your terminal, execute this standard curl request targeting our upload endpoint:

curl -X POST -F "file=@webgpu-demo.html" https://drpr.host/api/v1/upload

The API will respond instantly with a JSON payload containing your live HTTPS URL:

{
  "success": true,
  "url": "https://drpr.site/demo-a9f8b2",
  "expires_in": "15 days"
}

Alternatively, if you prefer using our streamlined command-line interface, install the utility and run:

drpr upload webgpu-demo.html

Common questions

Why is drpr.host preferred over GitHub Pages or Vercel for hackathon demo links?
Traditional hosting platforms force you to initialize a Git repository, configure environment settings, commit code, and wait for CI/CD pipelines to build. During a fast-paced hackathon, this process breaks your flow. drpr.host requires no accounts, no configuration, and no Git push, taking your WebGPU file from Claude Code to a live HTTPS link in under a second.
Will my WebGPU code run correctly on drpr.site domains?
Yes. WebGPU is strictly gated behind secure contexts in modern web browsers. Because drpr.host serves every hosted file over a highly secure HTTPS connection with automated SSL termination, your WebGPU render pipelines, compute shaders, and canvas elements will execute perfectly without any browser security blocks.
What are the file limits and hosting durations for the free tier?
Our zero-friction free tier allows direct, anonymous uploads of self-contained files up to 5 MB in size. Your uploaded WebGPU demo links will remain fully functional and live online for 15 days, which easily covers the judging and review windows for any standard hackathon.
Can I convert my temporary hackathon link into a permanent deployment?
Yes. While anonymous uploads are automatically deleted after 15 days to save resources, you can upgrade to a paid drpr.host developer account at any point to make your links permanent, map custom domains, and bypass the 5 MB file size limit for larger WebGPU assets.
