Description

Pixlint is the most modern, lightweight, and powerful conversion tracking and pixel management plugin for WooCommerce and WordPress. Connect your Meta (Facebook) Pixel and Google Analytics 4 (GA4) (plus TikTok Pixel, Pinterest Tag, and Google Ads in Pro) with built-in server-side Conversions API (CAPI) and zero coding required.

In the post-iOS 14.5+ era, browser ad-blockers and privacy restrictions cause standard browser pixels to lose 20%–40% of conversion signals. Pixlint solves this with Dual-Channel Tracking: firing client-side browser tags while simultaneously sending robust, server-to-server CAPI events with automatic deduplication and SHA-256 Advanced Matching.

For documentation, tutorials, and support, visit the official website or read our Documentation Guides.

🌟 What Makes Pixlint Different?

  • Dual-Channel Browser & Server-Side (CAPI) Tracking: Maximize Event Match Quality (EMQ) and recover lost conversion signals without double-counting.
  • Automatic Event Deduplication: Shares a synchronous event_id between browser pixels and server APIs so ad networks recognize and deduplicate identical events.
  • Zero Site Speed Impact: All server-side CAPI requests are dispatched asynchronously and non-blocking — zero delay for shoppers during checkout.
  • Modern React Dashboard: Clean, intuitive admin interface with built-in deep-links to platform setup guides.
  • 100% HPOS & Block Checkout Compatible: Fully compatible with WooCommerce High-Performance Order Storage and modern Block/Cart checkout flows.
  • Advanced User Privacy & Role Exclusions: Automatically exclude Administrators, Shop Managers, or specific user roles from tracking to keep your analytics data pristine.

FAQ

Does Pixlint require WooCommerce to work?

No. While WooCommerce is required for e-commerce tracking (like ViewContent, AddToCart, and Purchase), you can install Pixlint on any standard WordPress site to track general PageView events, form submissions (Lead), and email/phone clicks (Contact).

Is the Meta Conversions API (CAPI) free to use?

Yes! Meta Conversions API is a free feature provided by Meta. You only need your Pixel ID and an Access Token generated from Meta Events Manager.

How does Pixlint prevent duplicate events?

Pixlint automatically attaches a unique event_id to both the browser tag and the server-side CAPI request for every action. When Meta or GA4 receives both signals, they automatically deduplicate them into a single accurate conversion.

Will server-side tracking slow down my checkout?

No. All server-side requests (Meta CAPI, GA4 Measurement Protocol, Pinterest CAPI, TikTok Events API) are executed asynchronously and non-blocking using wp_remote_post( ..., array( 'blocking' => false ) ). They have zero impact on page load speed or customer checkout times.

Does Pixlint support WooCommerce HPOS (High-Performance Order Storage)?

Yes. Pixlint is fully declared and tested compatible with WooCommerce HPOS and custom order tables.

Does Pixlint work with caching plugins?

Yes! Pixlint outputs its tracking code dynamically and handles AJAX events cleanly, ensuring complete compatibility with WP Rocket, LiteSpeed Cache, W3 Total Cache, Cloudflare, and server-level caching.

Where can I find my credentials?

Each field in the Pixlint Pixel Editor contains a direct “Where to find?” or “How to generate?” link that opens our step-by-step documentation guide for that specific platform.
