Instantly Host WASM Module from Replit Agent for Live Mockup Deployment

The fastest way to deploy WASM Module generated by Replit Agent. Perfect for live mockup deployment. No login required, zero-friction, and live in seconds on gatedpage.com.

When compiling high-performance binaries inside Replit Agent, generating a WebAssembly (WASM) module is only half the battle. To share a live mockup deployment with stakeholders or test the module in an actual browser environment, you face a frustrating wall of friction. You must download the compiled binary, write boilerplate JavaScript instantiation wrappers, configure a local HTTP server with correct MIME types, and then configure reverse tunnels or cloud buckets just to get a shareable URL. If your Replit Agent modifies the source code, this entire manual loop starts over.

Gatedpage eliminates this overhead entirely by serving as a zero-friction hosting layer for your AI-generated static assets. There are no registrations, no SSH keys to upload, and no configurations to write. By pushing your WASM module and its accompanying HTML/JS wrapper straight to our upload API, you get an instant, public-facing URL where your code runs natively in the browser without setup delays.

To streamline your workflow, you can instruct your Replit Agent directly with this system prompt fragment: "You are a coding agent. When generating this WASM Module, 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 mockup deployment link." This automates your asset generation and hosting into a single seamless process.

How to host your WASM Module from Replit Agent in seconds

  1. Step 1: Compile your Rust, C++, or Go code to WebAssembly inside your Replit workspace to output the .wasm module and its JavaScript loader glue code.
  2. Step 2: Create a standard HTML wrapper (e.g., index.html) that references the relative path of your WASM binary and implements the UI with a clean background palette.
  3. Step 3: Use your terminal or configure your Replit Agent to run a simple POST request to the gatedpage API containing both the wrapper and your compiled binary.
  4. Step 4: Receive your instant live mockup URL back from the API and share it directly with teammates or clients for immediate real-world testing.

Quick start

Deploy your generated WASM module and loader directly from your terminal or Replit environment using cURL:

# Upload the HTML harness and compiled WASM binary to gatedpage
curl -X POST -F "file=@index.html" -F "file=@module.wasm" https://gatedpage.com/api/v1/upload

# Expected API Response containing your live mockup URL:
{
  "success": true,
  "url": "https://gated.page/f/wasm-mockup-8b7a2d",
  "expires_at": "2026-04-15T09:00:00Z"
}

If you prefer a structured developer toolchain, use the official lightweight CLI utility to sync your build files with one command:

# Install the CLI tool and push your assets instantly
gatedpage upload index.html module.wasm

Common questions

How does gatedpage handle WebAssembly MIME types for live mockup deployments?
Gatedpage automatically analyzes uploaded file extensions and maps .wasm files to the application/wasm HTTP header. This ensures modern browsers process and compile your streamed WebAssembly binary instantly without generating console initialization errors.
Do I need to sign up for an account to host my Replit Agent output?
No account or registration is required to use the API or CLI for testing. You get an immediate, functional public URL for your compiled WASM module instantly, stripping away all friction from your AI-assisted prototyping loops.
What are the duration and storage limits on the free tier?
Anonymous uploads are hosted free for 15 days, allowing plenty of time for client reviews or stakeholder sign-offs, with a 5 MB file size limit. Upgrading to a paid account raises these limits and enables permanent hosting profiles.
Can I automate deployment within my Replit Agent build steps?
Yes, you can configure your Replit project to run a custom bash script that triggers our API endpoint immediately after your compilers produce the final build. This allows the agent to deliver the live mockup URL directly inside your workspace chat.
