About Really Simple CAPTCHA

Really Simple CAPTCHA is a lightweight PHP CAPTCHA plugin for WordPress, developed by Takayuki Miyoshi. It is most commonly used as an add-on to the Contact Form 7 plugin to add basic bot-prevention to contact forms. The plugin generates simple image-based CAPTCHAs with alphanumeric characters that users must solve before submitting a form.

Being minimal in design and easy to install, Really Simple CAPTCHA became widely adopted in the WordPress ecosystem. However, it has been noted that the CAPTCHAs it generates are relatively easy for bots to bypass, and modern alternatives like reCAPTCHA or hCaptcha offer stronger protection. The plugin is no longer actively developed but remains installed on millions of WordPress sites.
