What the author says it does

Protect your Contact Form 7 forms with Google reCAPTCHA V2, Google reCAPTCHA V3, hCAPTCHA, or Cloudflare Turnstile.

Easy integration and supports multiple forms on a single page.

Four CAPTCHA Options

Choose the CAPTCHA provider that works best for you:

Google reCAPTCHA V2 — Google’s classic “I’m not a robot” checkbox.
Google reCAPTCHA V3 — Google’s invisible, score-based bot verification.
hCAPTCHA — A privacy-first alternative that offers robust bot protection while keeping user data secure.
Cloudflare Turnstile — A modern CAPTCHA that verifies users in the background, only requiring a simple click if the visitor appears suspicious.

Simple Setup

Sign up with your chosen CAPTCHA provider and grab your Site Key and Secret Key.
Paste them into CF7 Captcha in your WordPress admin.
Add protection to any CF7 form in seconds using the shortcode provided in the same settings page.

Customizable Appearance

Each CAPTCHA widget supports customization options directly from the shortcode:

Size — Choose between normal and compact to fit your form layout.
Theme — Switch between light and dark themes (or auto for Turnstile) to match your site’s design.
Language — Force any CAPTCHA to render in a specific language for your audience.

All options are combinable, so you can mix and match to get the exact look you need.

Submission Insights (NEW in v0.1.7)

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.
