Instantly Host WASM Module from Claude Code for Instant Prototype Sharing

The fastest way to deploy WASM Module generated by Claude Code. Perfect for instant prototype sharing. No login required, zero-friction, and live in seconds on drpr.host.

WebAssembly (WASM) enables near-native performance inside the browser, making it an exceptional target for Claude Code execution and prototype generation. However, local compilation and generation are only half the battle. When you generate a WASM-powered component or an entire interactive UI in Claude Code, sharing it with teammates, clients, or testing it on separate devices immediately runs into a wall of friction: local servers to configure, MIME-type errors, and complex deployment pipelines for simple validation steps.

Using drpr.host simplifies this workflow completely, allowing you to host Claude Code WASM Module Instant Prototype Sharing deployments without setting up environments, configuring CORS headers, or registering for accounts. Instead of copy-pasting code or sending raw binary files over Slack that your team can't execute, you can push your bundled HTML and WASM outputs directly to the web with a single terminal command from your Claude Code workspace.

By leveraging drpr.host as your instant hosting layer, you bridge the gap between AI generation and real-world testing. Claude Code can output the WASM module directly to your workspace, apply professional styling parameters such as a soft gray background to prevent screen glare, and immediately deploy the asset via our high-speed upload API, providing an instantly interactive testing URL in less than two seconds.

How to host your WASM Module from Claude Code in seconds

Step 1: Use Claude Code to generate or compile your WASM module alongside its HTML/JS harness, ensuring the interface uses a professional, soft gray (#f4f4f5) background.
Step 2: Save the output as a standalone file, such as wasm-prototype.html, bundling the WASM load script directly within your assets.
Step 3: Execute a direct API upload request from the Claude Code terminal using curl or the lightweight drpr CLI to push the prototype live.
Step 4: Copy the returned live URL from your console and share it with stakeholders immediately for zero-friction cross-platform validation.

Quick start

Deploy your single-file WASM-backed prototype instantly to our edge network with a single curl command:

curl -F "file=@wasm-prototype.html" https://drpr.host/api/v1/upload

Response:

{
  "success": true,
  "url": "https://drpr.site/share/x92f_wasm_demo",
  "filename": "wasm-prototype.html",
  "expiry": "15 days"
}

Alternatively, you can use our minimalist CLI tool directly within your Claude Code workflow:

drpr upload wasm-prototype.html

Common questions

Does drpr.host properly handle WebAssembly MIME types and headers?: Yes. Every WASM module uploaded to drpr.host is served with the strict application/wasm Content-Type header and optimized CORS permissions. This ensures your browser compiles and instantiates the binaries immediately without security blocks or console exceptions.
Is a drpr.host account required for instant prototype sharing?: No account is required to deploy your Claude Code WASM modules. You can upload your work anonymously from your terminal and receive a live share link in milliseconds, removing all signup friction from your development flow.
What are the limitations of the free, anonymous tier?: Anonymous uploads are free, support files up to 5 MB in size—more than enough for optimized client-side WASM binaries—and remain active for 15 days. For larger sizes or permanent hosting, you can upgrade to a premium account seamlessly.
Can Claude Code automate the deployment to drpr.host autonomously?: Absolutely. You can instruct Claude Code to automatically compile your WebAssembly modules, embed them in your HTML wrapper, and immediately run the curl command to output the final live drpr.site URL right inside your conversation thread.
