BotDetect CAPTCHA Free - Limitations

The free version of BotDetect Captcha has certain limitations. If you want to remove them, you can purchase a license of the full BotDetect version.

1. BotDetect Trademark in CAPTCHA Images

BotDetect Captcha Free Version Trademark

The free version of BotDetect has a 50% chance of including a randomized BotDetect™ trademark in the background of generated Captcha images.

You can see how the Captcha image would look without the trademark by reloading it.

Upgrade

When using a paid BotDetect license, the trademark is never added to Captcha images, making them easier to read.

2. Demo CAPTCHA Sound

The free version of BotDetect has limited sound functionality, replacing the Captcha sound with "SOUND DEMO" for randomly selected 50% of all Captcha codes.

Sound Demo
 

This means that for 50% of all Captcha challenges generated, the sound will not match the code shown in the picture. The free version sound is not suitable for real world use, and only allows you to test the sound functionality before buying, or turn it off completely if you don't need it.

Upgrade

The paid BotDetect license allows you to make your Captcha protection accessible with true sound functionality.

BotDetect Captcha Free Version Link

The free version of BotDetect reserves the bottom 10px of each Captcha image for a link to the BotDetect website.

You can change the link rendering mode, so it is added to the whole Captcha image without any visible text instead, but you can not turn it off or customize its destination.

Upgrade

When using a paid BotDetect license, you can change the Url the Captcha help link points to and the text displayed, or turn the link off completely.

4. Remote CAPTCHA Script Include

The free version of BotDetect also adds a JavaScript include loaded from the captcha.com domain (remote.captcha.com/include.js) intended for future statistics collection and proof-of-work confirmation (still work in progress).

Upgrade

When using a paid BotDetect license, you can disable the remote script include in BotDetect configuration.

5. Limited Number of Protected URLs per Domain

In the free version, you are not allowed to use Botdetect Captcha on more than 1000 Urls per domain. The number of different websites and domains on which the free version can be used is not limited, as long as the 1000 Urls per domain limit is respected.

Upgrade

The paid BotDetect license doesn't have this limitation, but the exact usage restrictions vary between different license types.
