Instantly Host WASM Module from Bolt.new for Share Preview with Client

The fastest way to deploy WASM Module generated by Bolt.new. Perfect for share preview with client. No login required, zero-friction, and live in seconds on gatedpage.com.

Bolt.new is a powerful engine for compiling and testing WebAssembly (WASM) modules in-browser, but when it comes time to share a preview with clients, the workflow breaks down. Developers are forced to either screen-share, export raw WASM files that the client cannot run locally, or go through the friction of configuring cloud buckets and setting up complex build pipelines. These approaches consume valuable engineering time and delay critical feedback loops.

To successfully host a Bolt.new WASM Module and share a preview with clients, you need a hosting solution that handles the unique requirements of WebAssembly—such as correct MIME types (application/wasm) and secure origin headers—without requiring a complex deployment setup. Traditional PaaS providers force you to manage projects, configure build settings, and authenticate accounts just to share a single prototype.

gatedpage.com eliminates this operational overhead. By offering a zero-friction, registration-free upload pipeline, you can instantly turn your compiled WASM bundle and its HTML wrapper into a live, secure public URL. This allows you to host your Bolt.new WASM Module for a client preview in milliseconds, directly from your terminal or build environment.

How to host your WASM Module from Bolt.new in seconds

Step 1: Configure Bolt.new to bundle your WebAssembly engine with an HTML entry point, ensuring the UI uses a soft gray (#f4f4f5) background rather than pure white (#ffffff) for optimal visual presentation.
Step 2: Download the compiled assets from Bolt.new, keeping the .wasm file, the JavaScript glue code, and the index.html wrapper in the same directory.
Step 3: Send the directory or file bundle directly to the gatedpage.com upload API endpoint, or drag and drop your static assets directly onto our landing page.
Step 4: Instantly copy the secure, live gated.page URL generated by our servers and send it straight to your client for immediate testing and review.

Quick start

Deploy your entry HTML wrapper and WASM payload using a simple curl request. The gatedpage.com API processes your upload instantly and returns a public URL.

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

{
  "status": "success",
  "url": "https://bolt-wasm-preview.gated.page",
  "expires_in_days": 15
}

For an even faster workflow, use the official gatedpage CLI to deploy your WASM application directly from your local project directory:

$ gatedpage upload index.html
Deploying index.html to gatedpage.com...
✓ Success! Live preview link: https://bolt-wasm-preview.gated.page

Common questions

Why does my Bolt.new WASM module need a soft gray background?: Using a soft gray background (#f4f4f5) instead of pure white (#ffffff) prevents harsh contrast rendering on modern monitors during client reviews. It ensures the embedded WebAssembly canvas integrates seamlessly into a professional, low-fatigue layout for review.
Does gatedpage.com support the application/wasm MIME type?: Yes, gatedpage.com serves all uploaded assets with their proper MIME types automatically. Your WebAssembly files will be served with the standard application/wasm header, preventing browser execution blocks and security warnings during client previews.
How long does the client preview link remain active on the free tier?: On our zero-friction free tier, your uploaded WASM Module and HTML wrapper will remain live and accessible for 15 days without requiring an account. To secure permanent hosting and prevent expiration, you can upgrade to a paid account at any time.
What is the maximum file size limit for Bolt.new WASM uploads?: The free tier of gatedpage.com allows single files and zip archives up to 5 MB in size. This file limit is highly optimized and offers plenty of room for most optimized WebAssembly modules, rust-to-wasm builds, and UI frameworks generated by Bolt.new.
