Tutteng is a modern Laravel CAPTCHA generator package designed to protect forms and web applications from spam, bots, and automated submissions. It generates secure yet human-readable CAPTCHA challenges using multiple rendering styles that are difficult for OCR and automated bot systems to bypass.

Built specifically for Laravel applications, Tutteng provides an easy integration process, flexible customization options, and a clean developer-friendly API.

Why Tutteng?

Tutteng offers multiple CAPTCHA rendering engines and customizable image generation options to improve security while maintaining readability for real users. By randomly generating different CAPTCHA styles, patterns, and distortions, automated systems have a much harder time solving the generated challenges.

The package is lightweight, easy to configure, and suitable for login forms, registration forms, contact forms, checkout pages, and any other area vulnerable to spam or bot attacks.
