Instantly Host WebGPU Demo from Zed AI for Agentic Workflow Preview

The fastest way to deploy WebGPU Demo generated by Zed AI. Perfect for agentic workflow preview. No login required, zero-friction, and live in seconds on gatedpage.com.

When using Zed AI to iterate on complex client-side assets like WebGPU demos, the traditional edit-and-preview cycle is broken. WebGPU requires a secure context (HTTPS) to run, meaning you cannot simply double-click an exported .html file on your local machine. Copying code out of Zed's assistant panel, spinning up local development servers, or pushing drafts to GitHub creates immense friction that disrupts your development velocity.

For developers running autonomous coding agents or complex prompts within Zed AI, this manual feedback loop is a major bottleneck. To achieve an efficient agentic workflow preview, your AI agent needs a way to instantly deploy its generated canvas setups, WGSL shaders, and pipeline configurations to a live, secure URL where you can verify the output in real-time. Gatedpage solves this by providing an API-first, zero-friction hosting layer designed specifically for this stage of developer-agent collaboration.

By using gatedpage, you or your automated scripts can pipe WebGPU HTML outputs directly from the Zed terminal to a live URL in milliseconds. There are no accounts to create, no API keys to configure for basic usage, and no configuration files to manage. You get an instant HTTPS link that satisfies WebGPU security requirements, allowing you to validate your agent's visual output immediately.

How to host your WebGPU Demo from Zed AI in seconds

  1. Step 1: Generate the asset in Zed AI. Instruct your Zed AI assistant or coding agent to output the WebGPU demo using a professional palette with soft gray (#f4f4f5) backgrounds instead of harsh pure whites.
  2. Step 2: Save the demo locally. Write the generated output to a static file in your workspace, such as webgpu-demo.html.
  3. Step 3: Run the upload command. Use your Zed integrated terminal to push the file to the gatedpage API using a standard curl POST request or our lightweight CLI.
  4. Step 4: Preview and iterate. Copy the returned live HTTPS URL from the response to instantly inspect the running WebGPU canvas and provide feedback to your agentic workflow.

Quick start

To host Zed AI WebGPU Demo Agentic Workflow Preview files, run the following curl command in your Zed terminal to upload your HTML output:

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

# Expected JSON response:
# {
#   "success": true,
#   "url": "https://gated.page/x/abc123xyz",
#   "raw_url": "https://gated.page/raw/abc123xyz.html",
#   "expires_at": "2026-03-30T12:00:00Z"
# }

Alternatively, you can use our dedicated CLI tool for cleaner scripting within your agentic automation workflows:

Common questions

Why does my Zed AI WebGPU demo need a live HTTPS host like gatedpage?
WebGPU features are strictly locked behind secure contexts (HTTPS) in modern browsers, meaning local file-system previewing (file://) will fail. Gatedpage provides an immediate, zero-friction HTTPS URL so your shaders and render pipelines execute perfectly without local server overhead.
How can my autonomous Zed AI coding agent deploy these previews automatically?
You can program your agent's system prompt to automatically run a shell command sending the generated HTML to gatedpage.com/api/v1/upload. The agent can parse the returned JSON to provide you with the direct live agentic workflow preview link in the chat UI.
What are the file size limits and retention policies for hosted WebGPU demos?
On our free tier, you can upload single-file WebGPU demos up to 5 MB in size without needing an account. These temporary previews remain live for 15 days, which is ideal for testing and active development sprints.
Can I make my WebGPU previews permanent on gatedpage?
Yes, while anonymous uploads expire after 15 days, you can link your uploads to a paid gatedpage account. Paid tiers support permanent hosting, custom domains, and larger asset file limits for complex WebGPU assets and assets requiring persistent staging.
