Dia Bookmarks

Your bookmarks, one peek away.

Dia Bookmarks puts a full bookmarks manager into your browsers side panel — with one killer feature: it always knows which of your bookmarks are already open.

Already open? Jump there. Bookmarks that are open in a tab are highlighted and pinned to an "Open bookmarks" section at the top of the panel. Clicking them switches to the existing tab — even across windows, even after the page redirected — instead of opening yet another duplicate. The currently active tab is emphasized, and you can close tabs right from the panel.

A real bookmarks manager. • Full folder tree with item counts; Bookmarks Bar and Other Bookmarks as fixed sections • Instant search across titles and URLs • Drag & drop to reorder or move bookmarks and folders (folders auto-expand while dragging) • Double-click to rename inline, context menu for everything else (edit URL, copy URL, delete, …) • Quick add: hover any folder and file the current page there with one click — the button only appears while the page isn't bookmarked yet • Add dialog pre-filled with the current tab's title and URL

Peek before you commit. Open any bookmark in a Peek — a floating window that closes by itself when you click back into your browser. A small control bar lets you copy the URL (also ⌥⇧C), promote the page to a real tab, or close it.

Fast and private. No build, no frameworks, no accounts, no tracking. Everything runs locally in your browser; the extension never reads, stores, or transmits page content or browsing data. Light and dark mode included.

Built for The Browser Company's Dia browser. Works best together with its sibling extension DiaPeek.
