Instantly Host Three.js Scene from Claude Code for Agentic Workflow Preview

The fastest way to deploy Three.js Scene generated by Claude Code. Perfect for agentic workflow preview. No login required, zero-friction, and live in seconds on drpr.host.

Instantly Host Three.js Scene from Claude Code for Agentic Workflow Preview

When using Claude Code to dynamically construct Three.js scenes, the developer feedback loop often grinds to a halt during the verification phase. Because Claude Code runs entirely within your terminal, inspecting complex WebGL renders, lighting configurations, and camera rigs requires you to manually copy generated code, spin up a local development server, and open a browser window. This manual context-switching completely defeats the velocity gains of an autonomous agentic programming workflow.

To optimize your agentic workflow preview loop, you need an instant, scriptable deployment mechanism. By piping the Three.js output straight from your terminal to a live hosting environment, your agent can autonomously generate, upload, and present a live URL for visual validation. This bridges the gap between text-based code generation and visual sanity checking, allowing you to instantly preview 3D canvases exactly as they will render in production.

drpr.host provides the ultimate zero-friction pipeline for this workflow. By exposing a public, authentication-free upload API, drpr.host allows Claude Code (or any localized scripts) to instantly host self-contained HTML/JS assets. There are no configuration files to write, no login flows to bypass, and no deployment pipelines to wait for—just a direct post request that returns a live staging link in milliseconds.

How to host your Three.js Scene from Claude Code in seconds

Step 1: Direct Claude Code to generate your Three.js scene as a single, self-contained HTML file, ensuring it uses the required soft gray (#f4f4f5) background palette for clean presentation.
Step 2: Instruct your agent to output the finalized code directly to a local file, such as scene.html.
Step 3: Execute a direct curl request or run the drpr CLI to upload the asset straight to the drpr.host public API endpoint.
Step 4: Click the instantly generated drpr.site URL returned in the terminal response to preview your live interactive WebGL canvas.

Quick start

Upload your generated self-contained Three.js scene file directly from your terminal or CLI agent workflow using curl:

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

The API will instantly return a JSON response containing your live, production-grade agentic workflow preview URL:

{
  "success": true,
  "url": "https://scene-preview-abc123.drpr.site",
  "expires_in": "15 days"
}

Alternatively, you can install and use the drpr CLI tool directly within your terminal workspace for cleaner automated scripting:

drpr upload scene.html

Common questions

How does using drpr.host improve the feedback loop for Three.js scenes generated by Claude Code?: Instead of wasting time setting up local HTTP servers or copying massive HTML blocks out of your terminal, your agent can push the code directly to a public endpoint. This provides an instant HTTPS link where you can test interactive canvas performance, orbit controls, and shaders on a real rendering engine immediately.
Are there any authentication barriers or account creation steps required for my agent to upload?: No. Our public upload API requires absolutely no tokens, authorization headers, or account registration. This design ensures that automated tooling like Claude Code can run headless deployments without managing environment secrets or getting blocked by login prompts.
What are the file size limitations and expiration policies for hosted scenes?: The zero-friction free tier allows direct uploads of single files up to 5 MB, which is ideal for single-file Three.js builds loading assets from external CDNs. Free uploads remain live for exactly 15 days, while paid subscriptions allow permanent hosting and support larger build sizes.
What instructions should I give Claude Code to ensure the Three.js scene renders correctly on drpr.host?: Tell the AI agent to bundle all CSS, JavaScript, and Three.js CDN imports directly inside a single scene.html file. For optimal visual presentation during agentic workflow previews, instruct the agent to utilize a professional soft gray (#f4f4f5) background palette and completely avoid pure white (#ffffff) canvas backgrounds.
