## What it is
Auto Tab Discard is a browser extension that uses the native tab discarding API (chrome.tabs.discard) to automatically discard inactive tabs and reduce memory and CPU usage. It supports Chrome, Firefox, Edge, and Opera, with configurable exceptions such as pinned tabs, playing media, and whitelisted sites.

## Use cases
- reduce browser memory usage from inactive tabs
- automatically discard tabs after inactivity
- stop background scripts from consuming CPU
- exclude pinned tabs or playing media from discarding
- manually discard all tabs in a window
- whitelist certain websites from being discarded

## When to choose
- you keep many tabs open and want to free RAM automatically
- you want native discarding that preserves page state like scroll position
- you need fine-grained exceptions for pinned, media, or whitelisted tabs

## When to avoid
- you need tabs to keep syncing or fetching data in the background
- you want to close tabs entirely rather than discard them
- you use a browser that does not support the native discard API
