Tuck

Tuck is a local-first Chrome side-panel extension that makes tab cleanup safe, reversible, and fast. It keeps useful links and snippets at hand without turning the browser into another dashboard.

Highlights

• Safe cleanup. Inactive tabs are discarded only after active, pinned, audible, incognito, protected-tab, protected-domain, URL, and inactivity checks.
• Archive before close. Every tab is saved to chrome.storage.local and that write is confirmed before Chrome is asked to close it.
• Quick recovery. Search, restore, or delete archived tabs from the side panel.
• Useful saved items. Keep domain-aware links and snippets. Correct values inline and choose Copy, Open, or Edit as the primary action.
• Tuck tab grouping. Select Group tabs to collect matching ungrouped site tabs into native Chrome tab groups named Tuck. It never closes, merges, or changes existing groups.
• Local and customizable. Use accessible themes, custom theme validation, protected domains, and JSON export/import. No account required.

Privacy

Tuck has no account, backend, analytics, cloud sync, page-content scraping, cookies, tokens, or saved form values. Your archive, notes, preferences, and exports stay on your device.

How tab safety works

For every archive-and-close operation, Tuck validates the tab again immediately before acting. It builds the archive record, writes it locally, confirms the saved record, and only then calls chrome.tabs.remove. If saving fails, the tab is not closed and the side panel reports the error.

Protected tabs, protected domains, active tabs, pinned tabs (when enabled), audible tabs (when enabled), internal URLs, malformed URLs, and excluded incognito tabs are never eligible for automatic cleanup.

Permissions

• tabs reads tab metadata needed for inactivity, safety checks, restoration, and local archiving.
• storage keeps archives, notes, themes, and settings on this device.
• alarms schedules quiet cleanup checks.
• sidePanel opens the persistent browser side panel.
• contextMenus lets users deliberately save selected text as a note.
• tabGroups creates and labels native Chrome tab groups only after the user selects Group tabs.

Development

pnpm install
pnpm check
pnpm test:e2e
pnpm build

pnpm check runs linting, formatting verification, unit tests, and the production build. pnpm test:e2e runs the extension integration test. To regenerate the repository demo video, run pnpm demo:record.
