<p>NoCaptcha Spam Filter for Contact Form 7 provides a deterministic, cache-safe, multi-layered defense against automated form submissions for Contact Form 7 without the need for CAPTCHAs or external libraries.</p>
<p>The plugin uses a combination of:</p>
<ul>
<li>Unique Honeypot: A site-specific hidden field that traps bots.</li>
<li>Cryptographic Signing: Ensures form tokens are genuine and haven’t been tampered with.</li>
<li>Anti-Replay Nonces: Each submission is unique; tokens cannot be reused.</li>
<li>Time-Check Validation: Blocks bots that fill out forms faster than humanly possible.</li>
<li>Cache-Safe Architecture: Automatically detects stale tokens on cached pages and refreshes them via a lightweight REST API fallback.</li>
</ul>
<h3>Scope of Protection</h3>
<p>This plugin is designed to block the vast majority of automated spam submissions (99% of common web crawlers) in Contact Form 7, with zero impact on user experience or performance. However, please note:</p>
<ul>
<li>Not a WAF: It is not a substitute for a Web Application Firewall or server-level security layers for mitigating sophisticated DDoS attacks.</li>
<li>Targeted Attacks: Highly sophisticated bots using headless browsers or manual human bypasses (spam farms) fall outside the scope of lightweight algorithmic protection.</li>
</ul>
<p>For maximum security, we recommend using this plugin as part of a multi-layered defense strategy.</p>
<h3>Configuration (optional, only for advanced users)</h3>
<p>You can override defaults in ‘wp-config.php’:<br />
    <code>php<br />
define('CF7NCSP_DOMAIN_SALT', 'your-random-string');<br />
define('CF7NCSP_TTL', 2400);      // Token lifetime (seconds)<br />
define('CF7NCSP_MIN_TIME', 20);   // Minimum time before submission</code><br />
Recommendations<br />
* Use a long, random string for ‘CF7NCSP_DOMAIN_SALT’<br />
* Keep ‘CF7NCSP_MIN_TIME’ between 10–30 seconds</p>
<h3>Privacy Policy</h3>
<p>This plugin is designed with privacy-first principles:<br />
* No PII Collection: It does not collect, store, or transmit any Personally Identifiable Information (PII).<br />
* No Persistent IP Storage: IP addresses are used transiently for rate limiting and are not stored in plain form or retained beyond a short-lived, temporary cache.<br />
* Local Processing: All validation happens on your server. No data is sent to third-party services.<br />
* Cookieless: The plugin does not set any browser cookies.</p>
<h3>Disclaimer</h3>
<p>This plugin is provided “as is”, without warranty of any kind, express or implied. Use at your own risk. While best efforts have been made to ensure reliability and security, the author is not liable for any damages or losses resulting from its use.</p>
<p>** DEVELOPER’S NOTE: **</p>
<p>This plugin is designed to be a lightweight, “set and forget” solution. It focuses on stability and minimal maintenance, with updates provided as needed for bug fixes and compatibility with WordPress and Contact Form 7.

OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA)

This is a great plugin with a very responsive and knowledgable support team.

I emailed them yesterday with a kind of obscure WooCommerce feature request and they had a fix deployed within 12 hours.

Yes, it's a paid service if your site has any kind of volume at all, but it's extremely effective and fully built for privacy and GDPR compliant. We're trying to de-G00glify everything for our clients so their websites are not tracking users every move and implementing this service is part of our (slow and tedious) move in that direction. 

Pricing is perfect for agencies as they do tiers by actual # of API calls and no limit on the number of sites you can install this on. Most competitors we were looking at had per-site license structures that were not going to work for us.

Works well for default comment fields, WPForms and WooCommerce. Has some other integrations but those are the ones we tried.

If you have any doubts, just go back into your logs of spam that slipped through reCAPTCHA and Akismet and a honeypot... pick a message and enter the data on the app.oopspam.com dashboard you can edit the test data right there and it will show you what spam score their system would give that message.

Great Service

Protect your forms from spam with 99.9% accuracy - no CAPTCHA, no JavaScript, no tracking. Trusted by 3.5M+ websites.
