Optional browser form checks

For Webflow and other hosted sites, test the browser helper with your specific form setup before enabling it. Existing AJAX handlers can affect submission behavior.

  1. Add the custom attribute data-formshield to the form you want to check.
  2. Include the script below, replacing the domain and API key.
  3. Publish to a test page and try a genuine inquiry, a blocked message and a network failure.
<script src="https://jevshield.com/shield.js" data-key="YOUR_API_KEY"></script>

This helper reads message, email and name fields only. It fails open after 6 seconds and can be bypassed by direct submissions. It does not guarantee protection of a platform's submission quota. Use a server-side integration for enforcement.
