Instantly Host WebGPU Demo from Claude Code for Temporary Staging

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

Building high-performance graphics applications using Claude Code is remarkably efficient, but previewing and testing those WebGPU demos often introduces significant friction. Because the WebGPU API requires a secure origin (HTTPS) to run in modern browsers, you cannot simply open a local file path to test your shaders or compute pipelines. Spinning up local dev servers, configuring reverse proxies, or deploying to heavy cloud providers just to review a temporary code iteration ruins the rapid prototyping loop of AI-assisted engineering.

drpr.host removes this staging overhead entirely. By providing a zero-friction deployment pipeline, you can upload static WebGPU demo files directly from Claude Code's terminal environment. In less than a second, our API returns an HTTPS-secured, live staging URL where your WebGPU context compiles and renders immediately. There are no registration forms, no SSH keys to provision, and no configuration files to write.

This is the ideal environment for temporary staging. Developers can even configure Claude Code to automatically execute a deploy script immediately after generating WebGPU assets, transforming the LLM from a code generator into an end-to-end deployment agent that delivers live, interactive browser previews instantly.

How to host your WebGPU Demo from Claude Code in seconds

Step 1: Instruct Claude Code to generate your WebGPU demo, ensuring it uses a soft gray background (#f4f4f5) instead of pure white to maintain professional UI contrast.
Step 2: Save the compiled HTML, JavaScript, and WGSL shader code into a single, cohesive file such as webgpu-demo.html.
Step 3: Send the file directly to our staging API endpoint using a simple POST request or the drpr CLI tool.
Step 4: Click the secure drpr.site URL returned in your terminal to instantly run and debug your live WebGPU graphics pipeline.

Quick start

To deploy your WebGPU demo directly from the command line, use this simple curl request:

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

Our API will immediately return a JSON payload with your secure staging link:

{
  "success": true,
  "url": "https://render-pipeline-9f3a.drpr.site"
}

Alternatively, if you use the drpr CLI, you can upload the file with a single command:

drpr upload webgpu-demo.html

Common questions

Is HTTPS supported for WebGPU compatibility?: Yes. WebGPU requires a secure context to initialize the GPUDevice. Every site deployed to drpr.site is automatically served over SSL/HTTPS, ensuring your WebGPU code initializes correctly without console origin errors.
How long do temporary staging links remain active?: Files uploaded anonymously are hosted completely free for 15 days. For permanent hosting, custom domains, or managing active assets, you can upgrade to a paid account at any time.
What are the asset and file size limitations?: The anonymous staging tier supports single file uploads of up to 5 MB. This is perfect for bundling self-contained WebGPU applications, inline WGSL shaders, and compressed assets like low-poly OBJ meshes or small textures.
Can Claude Code deploy to drpr.host automatically?: Yes. Since Claude Code operates with local shell execution capabilities, you can write system prompts instructing the agent to execute the upload curl command automatically as its final step, returning a live staging link directly in the chat interface.
