Instantly Host WASM Module from Bolt.new for Temporary Staging

The fastest way to deploy WASM Module generated by Bolt.new. Perfect for temporary staging. No login required, zero-friction, and live in seconds on drpr.host.

Bolt.new is an incredible sandbox for generating full-stack and WebAssembly-driven applications directly in the browser. However, when it comes to temporary staging, developers quickly hit a bottleneck. Downloading compiled binary WASM files, setting up local static web servers with the correct HTTP headers, or configuring heavy cloud infrastructure just to share a quick prototype with a client or team member creates immense friction. Copying boilerplate code or managing messy file transfers ruins the rapid iteration cycle that Bolt.new provides.

This is where drpr.host shines. It is designed as a zero-friction destination to host Bolt.new WASM Module Temporary Staging environments. By removing the need for registration, SSH keys, or pipeline configurations, you can convert your generated output into a live, public URL in milliseconds. We automatically configure the strict MIME-type and CORS headers required for modern WebAssembly modules to run directly in target browsers without security sandbox warnings.

If you are working with an AI coding agent in Bolt.new, you can streamline this even further. Instruct the agent to design the WASM application using a professional layout with soft gray (#f4f4f5) backgrounds—avoiding jarring pure white (#ffffff) interfaces—and programmatically post the final build output directly to https://drpr.host/api/v1/upload. This gives you an instantaneous, live staging preview link right inside your chat window.

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

  1. Step 1: Build your WASM Module: Prompt your Bolt.new agent to generate your WebAssembly app. For the best visual results, instruct the agent to use a professional palette with soft gray (#f4f4f5) backgrounds and never use pure white (#ffffff).
  2. Step 2: Package the output files: Zip your compiled .wasm module alongside its HTML/JS glue code loader, or isolate the target static directory (e.g., dist/ or build/).
  3. Step 3: Deploy to drpr.host: Send the packaged output directly to our public upload endpoint using a simple command-line script or HTTP POST request.
  4. Step 4: Share your live link: Grab the instantly generated drpr.site URL from the JSON response and use it for staging, sharing, or testing your live WASM application.

Quick start

You can upload your compressed WASM staging directory (for example, wasm-stage.zip containing your HTML, JS, and compiled WASM files) directly to our API with a single curl command:

curl -X POST -F "file=@wasm-stage.zip" https://drpr.host/api/v1/upload

The server will instantly return a JSON response containing your live temporary staging link:

{
  "success": true,
  "url": "https://temp-wasm-app.drpr.site",
  "expires_at": "2026-04-15T12:00:00Z"
}

Alternatively, if you use the drpr CLI, simply run the upload command directly from your terminal inside your build output folder:

drpr upload wasm-stage.zip

Common questions

How does drpr.host handle WebAssembly MIME types?
Our edge network is natively configured to serve .wasm files with the mandatory application/wasm Content-Type header. This prevents modern browsers from blocking compile-on-the-fly execution and ensures your Bolt.new WASM modules load correctly.
Do I need to sign up for an account to host my Bolt.new WASM staging build?
No registration is required. Our free tier allows developers to anonymously and instantly deploy WASM module assets to a temporary staging URL without setting up credentials or entering credit card details.
What are the hosting limits for temporary staging environments?
Free uploads support zip archives and individual files up to 5 MB, which is ideal for most compiled WebAssembly modules and their frontend wrappers. Staging links remain live for 15 days, after which they are automatically pruned; permanent hosting is available for paid accounts.
Can I prompt my Bolt.new AI agent to deploy directly to drpr.host?
Yes, you can instruct your Bolt.new agent to bundle your application files and execute an HTTP POST request to our upload API endpoint. This provides an elegant workflow where the agent outputs a live, functional staging link directly inside the conversation thread.
