What the author says it does

Captcha adds GDPR compatible captcha code anti-spam protection (like Google ReCaptcha) to WordPress forms – comments form, registration form, lost password form, and login form. In order to post comments or register, users have to type in the code shown on the image. This prevents spam from automated bots & adds security. No external services (like Google ReCaptcha) are used. No API keys are needed, and no user-identifiable data is used so it’s GDPR compatible.

Features

Captcha position – comments form, login form, registration form, or lost password form.
Letters type – capital letters, small letters, or captial & small letters.
Captcha type – alphanumeric, alphabets or numbers.
Translation enabled.

The opening of the plugin's own description. The full text, installation notes and changelog are on its WordPress.org page.

Where this page's numbers come from

Read from the WordPress.org plugin API on October 31, 2026, when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
