BotDetect CAPTCHA Generator Homepage
BotDetect™ 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 Captcha images specifically designed to be out of reach of computer vision and OCR technologies. BotDetect also provides an audio Captcha alternative to keep websites accessible to people with impaired vision, enabling you to make WCAG and Section 508 compliant websites.
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 practically impossible to pass automatically.
This approach to Captcha security is validated by the BotDetect track record: we have over 3000 paying customers and not one confirmed case of automated Captcha breaking by spammers.
Visual Studio 2015 & .NET 4.6 Ready
BotDetect ASP.NET CAPTCHA v3.0.16 supports the latest Microsoft Visual Studio 2015 and .NET 4.6 releases.
Full support for all Android & iOS devices
BotDetect CAPTCHA v3.0.13 audio now works on Android and iOS devices. Unlike other Captchas, sounds are played directly on the form page, without opening the media player app.
It certainly helps that unlike recaptcha spyware joke, BotDetect doesn't operate under 'if we can doxx you then you are human' principles, and will not get your application rejected on national security grounds by the most of governments.
And by the way, BotDetect also works in China -- feel free to guess what captcha doesn't :)
