Hop Sidebar

Arc-style sidebar: pinned tiles with Gmail, Calendar and Chat previews, bookmarks as pinned tabs, and this window's tabs.

An Arc-style sidebar for Vivaldi and Chrome, in the browser's side panel. • Pinned tiles: bookmarks in a folder named "Pinned" show as a grid of icons at the top. ⌘1–⌘6 (Ctrl+1–6) open them. • Previews: hover the Gmail tile for your newest unread emails, the Google Calendar tile for today's and tomorrow's meetings, or the Google Chat tile for recent conversations. • Bookmarks that act like pinned tabs: each bookmark keeps its own tab, so clicking it brings you back to where you were in it. • Edit in place: right-click to rename or add folders, drag to rearrange, drop a tab or link to bookmark it. • The window's tabs below, with tab groups, and Arc's "Clear" to close the loose ones. • No duplicate tabs: when a link from another app opens a page that's already open, switch to it, keep both, or always switch. • Unread counts on bookmarks from tab titles (Gmail, WhatsApp, Slack, Outlook and more). In Vivaldi, Hop Sidebar becomes a panel, and an optional CSS mod (see the GitHub page) hides the panel bar and slims the panel to 220 px, for a single sidebar like Arc's. Nothing leaves your browser: no servers, no analytics. Open source (MIT): github.com/instilled/hop-chromium
