## What it is
Tab Out is a Chrome extension (Manifest V3) that replaces the new tab page with a dashboard of all open tabs, grouped by domain with homepage grouping, duplicate detection, and one-click tab closing. It runs entirely locally with no server, account, or external API calls.

## Use cases
- manage too many open browser tabs
- replace my new tab page with a tab overview
- find and close duplicate tabs in chrome
- jump to an open tab without opening a new one
- save tabs for later before closing them
- group open tabs by website domain
- tell apart localhost dev servers by port

## When to choose
- you use Chrome and open many tabs you forget to close
- you want a fully local, privacy-friendly tab manager with no account
- you juggle multiple localhost dev projects and need port visibility

## When to avoid
- you use Firefox, Safari, or Edge rather than Chrome
- you need cross-device tab sync or cloud backup of saved tabs
- you want a full session manager with saved window layouts

## Facets
- artifact type: plugin
- maturity: active
- function: developer-tools, ui-components, state-management
- domain: developer-tools, browser-extensions, web-development
- platform: browser, browser-extension
- tags: chrome-extension, tab-management, new-tab-page, manifest-v3, local-first, privacy
