Description

This demo allows you to easily experiment with various BotDetect parameters and their combinations, so you can see how powerful and customizable BotDetect Captcha is.

Please note that values in brackets (such as [Default] and [Random]) are not actual parameter values you can use directly in your code.

Localization

BotDetect installations include pronunciation sound packages (required for localized Captcha sounds) only for North-American locales by deafult. The Locale drop-down list values relect this fact.

You can specify any other locale string for the Locale parameter value (e.g. "en-GB", "ru", "zh-Hans"). However, not all character sets might be supported yet, and you will have to download the pronunciation sound package separately from our site when it's available.

You can always see the full list of locales for which we support both Captcha images and Captcha sounds – and download the required pronunciation sound packages – at the BotDetect 4 CAPTCHA localizations page.

Free Version Limitations

  • The free version of BotDetect includes a randomized BotDetect™ trademark in the background of 50% of all Captcha images generated.
  • It also has limited sound functionality, replacing the CAPTCHA sound with "SOUND DEMO" for randomly selected 50% of all CAPTCHA codes.
  • Lastly, the bottom 10 px of the CAPTCHA image are reserved for a link to the BotDetect website.

These limitations are removed if you upgrade your BotDetect license.
