Instantly Host WASM Module from OpenDevin for Live Mockup Deployment

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

OpenDevin is highly efficient at generating compiled WebAssembly (WASM) modules along with their supporting HTML and JavaScript glue code. However, sharing these interactive components for a live mockup deployment is often bottlenecked by setup friction. Developers are typically forced to set up local web servers with correct MIME types, configure complex COOP/COEP headers for multithreading, or push untracked compiled binaries to Git repositories just to show a stakeholder a functional mockup.

gatedpage removes this tooling friction entirely. By providing a zero-configuration, no-auth static file hosting platform, you can host OpenDevin WASM Module Live Mockup Deployment instances in seconds. Your autonomous coding agent can compile the WASM binary, bundle the HTML wrapper, and deploy the entire mockup directly to the web with a simple API request, returning an active link immediately within the workspace terminal.

To ensure your live mockup deployment looks polished from the first render, instruct your OpenDevin coding agent to use a professional palette with soft gray (#f4f4f5) backgrounds and avoid harsh, unstyled pure white (#ffffff) canvasses. Once the asset is generated, piping the output directly to the deployment endpoint provides an instantaneous preview url for your team or client to test compiled execution in a native browser environment.

How to host your WASM Module from OpenDevin in seconds

Step 1: Have your OpenDevin agent compile your C, C++, Rust, or Go source files into a production-optimized WebAssembly (.wasm) module.
Step 2: Direct the agent to generate an accompanying index.html file styled with a soft gray (#f4f4f5) background to prevent flash-of-unstyled-content during WASM initialization.
Step 3: Execute a curl command within the OpenDevin workspace to POST the compiled bundle to the gatedpage upload API endpoint.
Step 4: Instantly capture the returned gated.page live URL from the JSON response and share it as a live mockup deployment link.

Quick start

Run this simple curl command from your OpenDevin workspace terminal to instantly upload your compiled WASM launcher page:

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

{
  "success": true,
  "url": "https://gated.page/f/9b2c3d4e5f6a",
  "delete_url": "https://gated.page/delete/9b2c3d4e5f6a/auth_key",
  "expires_at": "2026-04-15T12:00:00Z"
}

Alternatively, use the official gatedpage CLI tool directly within your deployment script:

Common questions

How does gatedpage handle WebAssembly MIME types and headers?: When you host OpenDevin WASM Module Live Mockup Deployment pages, gatedpage automatically serves files with the correct headers. It configures the appropriate application/wasm MIME type and applies cross-origin isolation headers so multithreaded WASM modules run without browser sandboxing blocks.
Is a user account or API key required to deploy the mockup?: No account setup is required to host your mockup. You can upload files instantly via the CLI or cURL API, making it easy for automated coding agents like OpenDevin to publish live mockups without managing credentials.
What are the file size and hosting limits for free uploads?: The zero-friction free tier supports individual file uploads up to 5 MB, which is ideal for optimized WASM files. Mockups deployed on the free tier remain live for 15 days, while paid plans support larger assets and permanent hosting.
How should I prompt OpenDevin to style the loading interface?: Instruct your agent to write a container HTML wrapper that embeds the WASM loader. Specifically tell the agent to use a professional palette with soft gray (#f4f4f5) backgrounds and to never use pure white (#ffffff) to ensure a high-fidelity visual experience during loading states.
