OpenPanel.dev

OpenPanel is an open-source web and product analytics platform that serves as a privacy-friendly alternative to traditional analytics solutions. This WordPress plugin seamlessly integrates <a href="https://openpanel.dev" rel="nofollow ugc">OpenPanel</a> with your WordPress site while maximizing reliability and avoiding ad-blocker interference.
<h4>Key Features</h4>
<ul>
<li>🚀 Ad-Blocker Resistant: Serves analytics scripts and API calls from your own domain</li>
<li>📊 Real-Time Analytics: Get instant insights without processing delays</li>
<li>🔒 Privacy-Friendly: Cookie-less tracking that respects user privacy (no cookie banners needed!)</li>
<li>⚡ Performance Optimized: Caches scripts locally and uses efficient proxying</li>
<li>🎯 Product Analytics: Funnel analysis, retention tracking, and conversion metrics</li>
<li>📈 Web Analytics: Visitors, referrals, top pages, devices, sessions, and bounce rates</li>
</ul>
<h4>How It Works</h4>
This plugin integrates OpenPanel with WordPress in a blocker-resistant way:
<ul>
<li>Inlines <code>op1.js</code> directly into your pages (cached locally for 1 week; falls back to CDN if needed)</li>
<li>Bootstraps the OpenPanel SDK with your Client ID automatically</li>
<li>Proxies all SDK requests through WordPress REST API (<code>/wp-json/openpanel/</code>)</li>
<li>Preserves all request methods, headers, query parameters, and body data</li>
<li>Handles CORS properly for cross-origin requests</li>
</ul>
Why use a proxy? Serving scripts and data from your own domain origin avoids third-party blocking and improves tracking reliability significantly.

<li>🍪 No Cookie Banners Required: OpenPanel uses cookie-less tracking, so you don’t need annoying cookie consent banners</li>
<li>🛡️ GDPR Friendly: Compliant with privacy regulations without requiring user consent for basic analytics</li>
