Technical Details

SleepyTabs is made for Firefox with support for Chrome.

SleepyTabs is built using browser extension APIs and works by:

1. Monitoring tab activity using browser events
2. Storing tab information in the browser's local storage
3. Replacing inactive tabs with lightweight placeholder pages
4. Restoring tabs to their original state when needed

Privacy

SleepyTabs operates entirely within your browser. No data is sent to external servers, and all tab information is stored locally in your browser's storage.
