NoBot CAPTCHA generator is a form security solution using Captcha challenges, that are easy for humans but hard for bots, to prevent automated page posting. Bots are kept from accessing protected website functionality using generated Captcha images specifically designed to be out of reach of computer vision and OCR technologies.

Why NoBot?

BotDetect is unique among Captcha generators in offering many Captcha image and sound styles. While each of them is easily comprehensible to human users, randomly using multiple Captcha generation algorithms makes the generated Captcha challenge extremely difficult to pass automatically.

Features

• 20 secure & readable Captcha image styles
• Custom Captcha image size, format, color scheme
• Custom Captcha code length, style, character set
• Custom font for Captcha image text
