GTM Injector Pro

Inject custom Google Tag Manager (GTM) containers into any webpage on the fly.

⚡ GTM Injector Pro - Instantly inject and test any Google Tag Manager (GTM) container on the fly with a modern, zero-config browser extension. 🌟 Overview - GTM Injector Pro is a powerful, lightweight, and developer-friendly Google Chrome Extension built with Manifest V3. It is designed for web developers, digital analysts, and QA engineers who need to test, audit, or debug Google Tag Manager implementations on any live website without altering the source code. ✨ Key Features - MAIN-World Script Execution: Safely injects GTM containers directly into the page's main context (window.dataLayer), seamlessly bypassing strict page-level Content Security Policy (CSP) restrictions. - Persistent & Automatic: Once enabled, it automatically injects your container across all page navigations and tabs without requiring manual re-injection. - Minimalist Dark UI: Features a sleek, modern, distraction-free dark neon interface with smooth tactile button micro-animations. - Live In-Page Debug Banner: A discreet, non-intrusive floating status banner in the bottom-right corner confirms your active container ID in real-time, complete with a quick one-click toggle to turn off. - Privacy-First & Secure: Zero third-party telemetry, no external CDN dependencies, and open-source code. 📖 How to Use - Click the GTM Injector Pro icon in your Chrome toolbar. - Enter your target GTM Container ID (e.g., GTM-XXXXXXX). - Click Save & Inject (or toggle the switch to ON). - The extension instantly injects the container, updates the icon with a green status dot, and displays a subtle debug banner on the page.
