Tag Toolkit is your ultimate browser extension for mastering the scripts and meta tags on any webpage.

Whether you're a web developer, SEO specialist, digital marketer, or just a curious mind, Tag Toolkit provides deep visibility into the inner workings of a website's tags and scripts—both on load and dynamically injected.

• Meta & Script Tag Overview
  Instantly view all meta and script tags loaded with the initial page content. Understand the site's structure and the scripts it relies on right from the start.

• Dynamic & Asynchronous Tag Detection
  Detect scripts that are added dynamically after the initial load, such as those injected by third-party services like Google Tag Manager. The extension continuously monitors the DOM and updates results in real-time.

• Search Functionality
  Easily search and filter through all detected tags and scripts to find exactly what you're looking for.

• Tag Identification & Highlighting
  Automatically recognizes common scripts like Google Analytics and GTM, highlighting them clearly for faster analysis.

Displays all meta and script tags present in the page source during the initial load, including:

• Inline scripts
• External script sources
• SEO-related meta tags

Tracks and lists scripts that:

• Are added via JavaScript after page load
• Load asynchronously or via tag managers
• Continue loading dynamically as you interact with the page

This live monitoring ensures you don’t miss hidden or delayed tag injections.

You can install Tag Toolkit from the Chrome Web Store:
