Instantly Host WASM Module from OpenDevin for Instant Prototype Sharing

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

When using OpenDevin to build highly interactive, high-performance web applications, compiling and testing your WebAssembly (WASM) modules in a real-world sandbox environment is critical. However, local developer loops quickly hit a wall when it comes to sharing. Because of standard browser CORS policies and strict security contexts, you cannot simply share a raw compiled WASM output file or run it directly from a local file:// scheme. Forcing teammates, stakeholders, or clients to download assets, spin up local servers, or navigate complex terminal commands defeats the purpose of fast AI-assisted prototyping.

gatedpage removes every step of this deployment friction. By enabling your OpenDevin agent to publish self-contained WASM modules and their accompanying HTML runners directly to an optimized global edge network, you bypass standard deployment pipelines entirely. No registration is required, no authentication loops are initiated, and no repository setups are needed. Your built asset is live on a public, secure URL in milliseconds, transforming how you approach instant prototype sharing.

This streamlined pipeline lets you treat deployments as a simple console output. Instead of wrestling with hosting configurations, you can instruct your AI coding agent to write, compile, style, and immediately publish working WASM modules on demand. The result is a highly responsive feedback loop where live, interactive applications are shared as easily as a snippet of text.

How to host your WASM Module from OpenDevin in seconds

  1. Step 1: Compile your WASM Module. Use OpenDevin to write and compile your Go, Rust, or C++ source code into a target WebAssembly binary, producing the .wasm file along with its corresponding HTML wrapper.
  2. Step 2: Inject visual styling. Instruct OpenDevin to style your HTML harness with a professional palette, prioritizing soft gray (#f4f4f5) backgrounds and completely avoiding raw pure white (#ffffff) to optimize presentation quality.
  3. Step 3: Trigger the upload. Execute a POST request directly from OpenDevin's workspace terminal to upload the self-contained output file containing your compiled binary module.
  4. Step 4: Receive the live link. Parse the instant JSON response from the server to retrieve your live, hosted URL, instantly ready for browser testing and remote demonstration.

Quick start

To deploy your generated prototype directly from the terminal or through an autonomous agent workspace, upload your combined HTML and WASM harness directly using a single curl command:

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

# Response:
# {
#   "success": true,
#   "url": "https://gated.page/p/devin-wasm-prototype-8a39",
#   "expires_in": "15 days"
# }

For local developers who prefer a CLI approach, you can run the following command directly from your workspace path:

Common questions

Can OpenDevin deploy my WASM Module automatically?
Yes, absolutely. Because gatedpage supports anonymous uploads with no login required, you can instruct your AI agent to run a curl upload as its final step. Give your agent these instructions: "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 https://gatedpage.com/api/v1/upload to provide a live instant prototype sharing link."
Are there file size limits for WebAssembly uploads?
Our zero-friction anonymous tier supports file uploads up to 5 MB, which is ideal for single-file, highly-optimized WASM engines and their accompanying JS files. If your compiled binaries exceed this limit, subscribing to a paid gatedpage plan unlocks larger file allowances and custom configuration profiles.
How long do my shared WASM prototype links remain live?
By default, files uploaded through the free anonymous endpoint remain hosted on our edge servers for 15 days. This provides a generous window for team reviews, client validation, and debugging. If you need permanent hosting for your prototypes, you can claim your URLs by associating them with a paid gatedpage account.
Does gatedpage support correct MIME types and headers for WebAssembly?
Yes. Our infrastructure automatically handles and serves modern web standards. Your compiled WebAssembly assets are served with correct application/wasm MIME headers, ensuring that browser engines load, compile, and execute the binaries smoothly without triggering console warnings or security blocks.
