SmartField vs CAPTCHA for Bot Blocking
A direct comparison of SmartField and CAPTCHA / reCAPTCHA for protecting sensitive form data.
CAPTCHA / reCAPTCHA
CAPTCHA asks users to prove they're human. It doesn't protect form data from JavaScript.
// With CAPTCHA / reCAPTCHA:
document.querySelector('input').value
// "SensitiveData123" ← readable
SmartField
SmartField blocks bots by architecture (Shadow DOM), not by puzzles. No user friction. Bots can't find, fill, or read the input.
// With SmartField:
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6..." ← AES-256 encrypted
