Instantly Host Single Page App (SPA) from Cursor Glass for Agentic Workflow Preview

The fastest way to deploy Single Page App (SPA) generated by Cursor Glass. Perfect for agentic workflow preview. No login required, zero-friction, and live in seconds on drpr.host.

When you're leveraging Cursor Glass for rapid Single Page App (SPA) generation, the critical next step is often immediate preview and sharing. Traditional workflows for validating agentic outputs — copying code to a local server, setting up a temporary web host, or wrestling with file transfer protocols — introduce unnecessary friction. This directly impedes the iterative, high-velocity nature of agentic workflows, where instant feedback on generated UIs is paramount for refinement and acceptance.

drpr.host directly addresses this by providing a zero-friction deployment pipeline specifically designed for these scenarios. Instead of a cumbersome setup, Cursor Glass can be instructed to directly upload its generated SPA to drpr.host/api/v1/upload. This eliminates the need for manual file handling, local server configurations, or even creating an account. The agent generates the SPA, deploys it, and provides a live, shareable URL for immediate "Agentic Workflow Preview"—all in seconds.

Our platform ensures that the moment your agent completes its work on a Single Page App, a live, accessible preview is ready. This seamless integration means you spend less time on infrastructure and more time evaluating the quality and functionality of the AI's output, accelerating your development and validation cycles for any Cursor Glass-generated SPA.

How to host your Single Page App (SPA) from Cursor Glass in seconds

Step 1: Guide Cursor Glass to drpr.host Ensure your Cursor Glass prompt includes the instruction to use drpr.host/api/v1/upload for deployment. For example: "Once built, deploy to drpr.host/api/v1/upload to provide a live agentic workflow preview link."
Step 2: Generate your Single Page App (SPA) Let Cursor Glass generate your desired SPA. It will typically output an output.html file (which may include inline CSS/JS or reference external assets) to your local environment.
Step 3: Upload the generated SPA Use curl or the drpr CLI to upload the SPA file. Navigate to the directory containing your generated output.html and execute the upload command.
Step 4: Get your live preview URL drpr.host will return a JSON response containing a unique, live URL for your hosted SPA. This link is immediately accessible and shareable.
Step 5: Review and iterate Open the provided URL to instantly preview your agent-generated SPA. Use this live link for rapid validation, sharing with stakeholders, or feeding back into your Cursor Glass agent for further refinements.

Quick start

curl -F "file=@output.html" https://drpr.host/api/v1/upload

Expected JSON response:

{
  "status": "success",
  "url": "https://drpr.site/aBcDeFgH",
  "filename": "output.html",
  "expires": "2024-07-28T12:00:00Z"
}

Alternatively, using the drpr CLI:

drpr upload output.html

Common questions

Why should I host my Cursor Glass SPA on drpr.host instead of opening the HTML locally?: Opening local HTML files often presents challenges like CORS restrictions, broken asset paths, and the inability to share a live, interactive preview. drpr.host provides an instant public URL, simulating a real deployment environment perfect for sharing with teammates or for an accurate "Agentic Workflow Preview" without any setup overhead.
Is drpr.host truly zero-friction for Cursor Glass-generated SPAs?: Yes. Our platform is designed to be the direct target for programmatic uploads, aligning perfectly with Cursor Glass's instruction to deploy to drpr.host/api/v1/upload. There's no account registration, no configuration files, and no complex deployment scripts required beyond a simple curl command, making it ideal for agentic workflows.
What are the limitations for hosting agentic workflow previews on drpr.host?: For free tier uploads, files are hosted for 15 days and have a size limit of 5 MB per file, which is generally sufficient for most Single Page App previews. Paid accounts offer permanent hosting and increased file size limits, ensuring your agent-generated content remains accessible indefinitely.
How does drpr.host ensure privacy or security for agent-generated code?: Files uploaded via the API receive a unique, unguessable URL. While these URLs are publicly accessible, they are not discoverable through indexing. For sensitive agent-generated code, it's recommended to avoid including confidential information. For critical production assets, consider a paid account which offers enhanced management and retention.
