Unlike other captchas, IconCaptcha spares users the need of deciphering hard-to-read text images, solving complex math problems, or engaging with perplexing puzzle games. Instead, with IconCaptcha it's as straightforward as comparing up to 8 icons and selecting the least common one. IconCaptcha doesn't just prioritize users; it's also developer-friendly. In just a few steps, you can have IconCaptcha integrated into your website. Even if you're new to PHP and JavaScript, installing IconCaptcha is a straightforward process. The included demo pages in this repository provide all the necessary code to get IconCaptcha up and running. For more in-depth insights, take a moment to explore the information provided on this page and the wiki. --- ### [β–Ά Try the live demo here!](https://www.fabianwennink.nl/projects/IconCaptcha/#!demonstration) [](#-try-the-live-demo-here) [![IconCaptcha light and dark theme widget examples.](https://camo.githubusercontent.com/0a5f43d14977b5390cb04f3ae1c6050c9259acb883200b0f4ad05637df9bcb27/68747470733a2f2f692e696d6775722e636f6d2f5773576442524c2e706e67 "IconCaptcha widget examples")](https://camo.githubusercontent.com/0a5f43d14977b5390cb04f3ae1c6050c9259acb883200b0f4ad05637df9bcb27/68747470733a2f2f692e696d6775722e636f6d2f5773576442524c2e706e67) **[Using ASP.NET instead?
