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 1. Sign up with your chosen CAPTCHA provider and grab your Site Key and Secret Key. 2. Paste them into **CF7 Captcha** in your WordPress admin. 3. 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) Go beyond just blocking spam. Submission Insights gives you full visibility into every form submission: * **Sender IP** — See the IP address of the person who contacted you. * **Source Page** — Know exactly which page on your site the form was filled out on. * **Device & Browser** — Get technical details about the sender’s setup. ### Want More? Upgrade to CF7 Captcha Pro This free version gives you solid CAPTCHA protection. **CF7 Captcha Pro** adds six extra layers of spam defense on top of what you already have here, plus a full set of tools to capture and act on every lead your forms collect. ### What you get with Pro **6-Layer Spam Defense** — additional spam-blocking methods that work quietly in the background: – **Advanced Honeypot** — invisible trap fields with names that regenerate every 24 hours. – **Time Limit Validation** — bots submit in 0.2 seconds. Humans take 15–30. This blocks anything that moves too fast (or stays too long).–** Rate Limiting** — caps submissions per IP so bot networks can’t flood your inbox or burn through your email quota. – **Geographic Blocking** — whitelist only the countries you serve, or blacklist known spam regions. – **IP Pattern Blocking** — block single IPs, wildcards, CIDR ranges, or entire subnets when you know exactly where an attack is coming from. – **Word Filter** — scans every submission for spam keywords, phishing URLs, and known scam phrases before it reaches you. **Lead Recovery** — captures form data in real-time as visitors type, so you don’t lose leads from abandoned forms. **Database Storage & Export** — every submission is saved with full metadata (IP, browser, referrer, timestamp). Export to CSV, Excel, JSON, or PDF whenever you need it. No more lost leads if your email fails. **Webhooks** — send form data instantly to any URL. Connect to Zapier, Salesforce, Slack, Google Sheets, or any custom API. Multiple webhooks per form, with retry logic built in. **Mailchimp Integration** — submissions automatically added to your Mailchimp lists. Field mapping, tags, opt-in handling. **Twilio SMS** — receive instant alerts for every submission or send automated SMS replies to your clients. **Comprehensive Logging** — every spam block, webhook call, and integration event is logged. Debug any issue in minutes instead of hours. 👉 **[Get CF7 Captcha Pro](https://lukasapps.de/wordpress/plugins/cf7-captcha-pro/)** ### External services This plugin relies on third-party CAPTCHA providers to detect and block spam submissions on your Contact Form 7 forms.
