Overview

ZenStack is a Chrome extension that replaces the new tab page with a bookmark dashboard. Users organize links on Kanban-style boards, see quick links and frequently visited sites, and search their bookmarks—all in one place. Optional Pro (zenstack.space) adds extra features; the core experience works without sign-in.

Highlights

Kanban boards – Create boards and columns (e.g. To Read, Work) and add links as draggable cards.
Chrome bookmark sync – Uses the Chrome bookmarks API so saved links stay in sync with native bookmarks.
Quick save – Popup and "Save to ZenStack" context menu to save the current page to a board.
Search – Search across boards and bookmarks from the dashboard.
Custom new tab – Live wallpapers, light/dark theme, and configurable layout.
Optional Pro – Subscription (zenstack.space) for extra features; core experience works without sign-in.
