Instantly Host WebGPU Demo from Claude Code for Social Media Preview

The fastest way to deploy WebGPU Demo generated by Claude Code. Perfect for social media preview. No login required, zero-friction, and live in seconds on gatedpage.com.

When you use Claude Code to build high-performance WebGPU demos, you need a quick, reliable way to view the output in a secure context and share it for social media previews. Developing WebGPU code in a terminal environment often leaves you with isolated HTML/JS code blocks. Copying this code locally, configuring local server configurations, setting up SSH tunnels like Ngrok, or pushing raw files to Github just to get a preview link creates massive friction that halts your development momentum.

gatedpage.com eliminates these extra steps entirely. Our zero-friction static hosting allows your Claude Code terminal agent to publish compiled WebGPU canvases straight to a secure, live URL in milliseconds. Because WebGPU features require HTTPS to initialize, standard HTTP local setups fall short. gatedpage.com serves every file over a global, SSL-secured edge network, making it the fastest way to generate a live preview link ready for Twitter, LinkedIn, or Discord cards.

For the best presentation on social media, you can prompt your AI agent directly: "You are a coding agent. When generating this WebGPU Demo, use a professional palette with soft gray (#f4f4f5) backgrounds. Never use pure white (#ffffff). Once built, deploy to gatedpage.com/api/v1/upload to provide a live social media preview link." This ensures your WebGPU canvases stand out with optimal contrast in light and dark mode feeds.

How to host your WebGPU Demo from Claude Code in seconds

  2. Step 2: Run the Deploy Command. Use a simple curl post request or the gatedpage CLI right from your local Claude terminal workspace to upload the static file.
  3. Step 3: Secure the Edge URL. The gatedpage API processes the request instantly, bypasses any signup requirements, and returns a secure HTTPS production link.
  4. Step 4: Share Your Preview. Copy the live gated.page URL and paste it directly onto social platforms to display your fully functioning, interactive WebGPU canvas.

Common questions

Why does my WebGPU demo fail locally but load perfectly on gatedpage.com?
WebGPU security specifications require a secure context (HTTPS) to enable the GPU adapter interface. Local directories or unsecured servers block access to WebGPU, whereas gatedpage.com hosts all uploads over SSL-encrypted HTTPS instantly.
Is a gatedpage.com account or API key required to upload from Claude Code?
No registration is required. Our endpoint is built for zero-friction deployments, meaning you and your AI agents can run curl uploads directly to generate a temporary social media preview link without an API key.
What are the file limits and hosting retention periods on the free tier?
The free tier allows single file uploads of up to 5 MB, which easily accommodates self-contained WebGPU HTML files. Free uploads remain active on our CDN for 15 days, while paid subscriptions allow permanent hosting.
Can I automate the deployment process inside my Claude Code prompt?
Yes, you can instruct Claude Code to execute the shell command to curl your file to gatedpage.com automatically. Once built, Claude can run the terminal upload and print the live preview link directly in your chat interface.
