Tsukuyomi by Arnab

Tsukuyomi is a modern browser extension built with React 19 and TypeScript that provides an intuitive interface for managing browser tabs. Unlike automatic tab suspension extensions, it gives you complete control over which tabs to suspend and when, making it perfect for users who want manual control over their browsing experience.

Modern browsers can consume enormous amounts of RAM with multiple tabs open. Each tab can use 50-200MB+ of memory, and with dozens of tabs, your system can slow to a crawl. Tsukuyomi solves this by allowing you to manually suspend tabs, reducing their memory footprint while keeping them accessible in your tab bar.
