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
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.
When using a paid version, 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.
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.
The paid versions allow you to make your Captcha protection accessible with true sound functionality.
3. Fixed CAPTCHA Link
The free version of BotDetect reserves the bottom 10px of each Captcha image for a link to the BotDetect website.
You can alter the link text, or 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.
When using a paid version, you can change the Url the Captcha help link points to or turn the link off completely.
4. Remote CAPTCHA Script Include
captcha.com domain (
remote.captcha.com/include.js). Its future uses include, but are not limited to, statistics collection and proof-of-work confirmation (still work in progress).
When using a paid version, you can disable the remote script include in BotDetect configuration.
5. Limited numbers of Captcha Image Styles
The free version of BotDetect Captcha contains selected 50 image styles, while other image styles are restriced to paid version only.
When using a paid version, all image styles are enabled.
6. Limited numbers of Captcha Sound Styles
The free version of BotDetect Captcha contains selected 10 sound styles, while other sound styles are restriced to paid version only.
When using a paid version, all sound styles are enabled.
7. 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.
The paid versions don't have this limitation.
