Instantly Host WebGPU Demo from Cursor Glass for Agentic Workflow Preview

The fastest way to deploy WebGPU Demo generated by Cursor Glass. Perfect for agentic workflow preview. No login required, zero-friction, and live in seconds on drpr.host.

Developers leveraging Cursor Glass for rapid WebGPU demo generation understand the power of an "Agentic Workflow Preview." The challenge, however, often lies in instantly sharing and iterating on these visual outputs. Generating a WebGPU demo with Cursor is fast, but then manually copying the code, setting up a local server, and figuring out a shareable URL introduces significant friction, breaking the seamless agentic flow. drpr.host is purpose-built to eliminate this impedance mismatch, enabling immediate, shareable previews.

When your Cursor Glass agent generates a WebGPU demo, following instructions like using a professional palette with soft gray (#f4f4f5) backgrounds and avoiding pure white (#ffffff), the next logical step isn't saving locally—it's getting a live, shareable URL. The traditional path involves messy local file transfers, creating temporary Gists, or relying on screenshots, none of which provide an interactive, real-time preview. This significantly hampers the agentic feedback loop, where immediate visual validation and collaborative review are paramount.

drpr.host integrates directly into this agentic workflow by providing a zero-friction endpoint for your generated WebGPU demos. Simply output your HTML file and use a single API call to upload it, instantly receiving a live URL. This direct deployment to drpr.host/api/v1/upload provides an "Agentic Workflow Preview" link in seconds, allowing you to bypass manual serving, eliminate file transfer overhead, and keep your development cycle as fluid and responsive as Cursor Glass itself.

How to host your WebGPU Demo from Cursor Glass in seconds

Step 1: Instruct Cursor Glass to generate your WebGPU demo, ensuring it outputs the full HTML content to a specified file, such as output.html.
Step 2: Review the generated HTML file locally to confirm the WebGPU demo renders as expected, adhering to any specific styling instructions you provided (e.g., using soft gray backgrounds).
Step 3: Utilize the provided curl command or the drpr CLI tool to upload your generated HTML file to drpr.host. This action immediately pushes your demo live.
Step 4: drpr.host will respond with a unique, publicly accessible URL where your WebGPU demo is hosted, along with a delete URL and expiration information.
Step 5: Use this live URL for instant "Agentic Workflow Preview," sharing it with team members, integrating it into automated reports, or embedding it for further review without any additional configuration.

Quick start


# Upload your WebGPU demo directly from the command line using curl
curl -F "file=@output.html" https://drpr.host/api/v1/upload

# Expected JSON response:
{
  "success": true,
  "filename": "output.html",
  "url": "https://drpr.site/a1b2c3d4e5f6g7h8.html",
  "delete_url": "https://drpr.host/api/v1/delete/a1b2c3d4e5f6g7h8",
  "expires_in_days": 15
}

# Alternatively, if you have the drpr CLI installed:
drpr upload output.html

Common questions

Why shouldn't I just view my Cursor Glass WebGPU Demo locally?: Viewing locally prevents immediate sharing, collaborative review, and cross-device validation, which are crucial for "Agentic Workflow Preview." drpr.host provides an instant public URL, enabling seamless integration into automated processes or team discussions, extending beyond your local development environment.
Is an account required to host my Cursor Glass WebGPU Demo on drpr.host?: No, drpr.host offers zero-friction uploads for individual files without requiring an account or login. This design choice prioritizes speed and integration into rapid development and agentic workflows, ensuring your WebGPU demos are live in seconds.
How long will my WebGPU Demo from Cursor Glass remain live on drpr.host?: Files uploaded via the free tier are hosted for 15 days. For use cases requiring permanent hosting or larger file sizes than the free tier's 5 MB limit, drpr.host offers paid accounts with extended features and retention.
What are the file size limitations for hosting WebGPU Demos on drpr.host?: On the free tier, individual files are limited to 5 MB. This capacity is typically sufficient for most WebGPU demos generated for rapid "Agentic Workflow Preview." Paid plans provide significantly increased file size limits and additional hosting benefits.
