Tab Resource Usage Dashboard is a free Chrome extension designed to enhance browser performance by monitoring tab resource usage in real-time. It provides users with detailed insights into each tab's memory consumption and performance metrics, allowing for effective identification of resource-heavy tabs. Key features include a real-time performance score, memory analysis, detection of long-running tasks, and resource tracking, which collectively help users manage their browsing experience more efficiently.

The extension is particularly useful for developers and power users who frequently handle multiple tabs. It monitors various parameters such as JavaScript memory usage, DOM node counts, active timers, and total bandwidth consumed. With an intuitive dashboard that updates every five seconds and color-coded indicators for resource usage, users can easily pinpoint problematic tabs. Importantly, all data analysis is conducted locally, ensuring user privacy is maintained.
