DOM Mutation Debugger is a Chrome extension designed for web developers to visualize DOM changes directly on their web pages. This tool eliminates the need for keeping DevTools open by highlighting elements that have mutated in real time, allowing for a more intuitive debugging experience. Key features include tooltips that provide detailed mutation information, the ability to save mutation data as a global variable, and customizable settings to filter and group mutations based on various criteria.

The extension supports both light and dark themes and includes a Sentry Mode for continuous monitoring of elements that may be mutating in loops. The tooltip structure offers insights into the mutated element, the number of mutations, and the mutation type, ensuring developers have access to crucial information at their fingertips. Notably, the extension respects user privacy by not collecting or sharing personal data.
