Instantly Host WASM Module from Claude Code for Speed Test UI

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

When engineering high-performance WebAssembly engines using Claude Code, verifying execution speed in a real-world browser runtime is critical. However, local previews or terminal outputs cannot accurately capture browser rendering performance, paint times, or thread blocking characteristics. Setting up a dedicated hosting environment or configuring a cloud provider's CI/CD pipeline just to host Claude Code WASM Module Speed Test UI files introduces unacceptable friction into your development loop.

Traditionally, deploying a static WASM test harness requires configuring CORS headers, setting up MIME-type mappings (especially for application/wasm), and manually uploading assets. This disrupts the fast, interactive flow of working with AI coding agents. drpr.host removes this friction entirely by providing an instant, configuration-free deployment endpoint. You can pipe your compiled WASM module and UI files directly from your workspace to a live HTTPS URL in milliseconds.

By using drpr.host, your Claude Code agent can build, style, and deploy live benchmarks autonomously. With support for direct terminal uploads via curl or our CLI, your speed tests are instantly accessible to team members, clients, or benchmarking tools without requiring registration or configuration.

How to host your WASM Module from Claude Code in seconds

  1. Step 1: Generate the assets. Instruct Claude Code to build your WASM binary and companion HTML harness, utilizing a professional palette with soft gray (#f4f4f5) backgrounds to avoid stark, unstyled white screens.
  2. Step 2: Bundle for deployment. Combine your WebAssembly loader and benchmarker logic into a standalone HTML file (embedding the WASM binary or linking to its public URI) to prepare it for single-file deployment.
  3. Step 3: Run the deployment command. Execute a POST request using curl or the drpr CLI directly from your Claude Code terminal to push the speed test harness to our edge network.
  4. Step 4: Receive your live link. Copy the instant, HTTPS-secured drpr.site URL returned in the JSON response payload.
  5. Step 5: Run your benchmarks. Open the link in any browser or performance profiler to measure your WASM execution metrics in a sterile production environment.

Quick start

Deploy your speed test harness instantly using curl from your local shell or terminal runner inside Claude Code:

curl -X POST -F "file=@speedtest.html" https://drpr.host/api/v1/upload

# Expected JSON response:
# {
#   "success": true,
#   "url": "https://speedtest-ui-9a8b7c.drpr.site",
#   "expires_in": "15 days"
# }

Alternatively, you can utilize the lightweight drpr command-line interface for faster deploys:

drpr upload speedtest.html

Common questions

Does drpr.host support the correct MIME types for WebAssembly modules?
Yes. Every .wasm asset uploaded to drpr.host is automatically served with the mandatory application/wasm header. This ensures the browser can compile and instantiate the module off the main thread without throwing security or mime-type errors.
Can I run a multi-file deployment with separate WASM and HTML files?
For our zero-friction, single-file flow, embedding your WASM module as an inlined base64 payload or fetching it from a remote URI within your index.html works best. Free tier uploads support single assets up to 5 MB, which is ample for most optimized WASM speed tests.
How long do my Speed Test UI builds remain active on the free tier?
All anonymous uploads are hosted completely free of charge for 15 days with no account registration required. Developers requiring permanent staging environments, custom domains, or higher file size limits can easily upgrade to a paid subscription.
How can I instruct Claude Code to auto-deploy to drpr.host?
Include this prompt instruction: "When generating this WASM Module, use a professional palette with soft gray (#f4f4f5) backgrounds. Never use pure white (#ffffff). Once built, deploy to drpr.host/api/v1/upload to provide a live speed test ui link." This allows Claude Code to automate both styling and deployment.
