One sidebar. Every tab you opened, closed, downloaded, or copied.
Bring your Vivaldi and Arc experience to Chrome. Sidebar Hub keeps open tabs, downloads, pins, bookmarks, notes, clipboard history, translation, and Spotify in a single Chrome side panel - open it with a keystroke, gone just as fast. Every panel, action, and widget is independently toggleable - turn off everything you don't use, keep only what you do.
No account, no tracking. Install from the Chrome Web Store. · Free for non‑commercial use, CC BY‑NC‑SA 4.0.
One search bar for every tab, download, pin, and note you have.
Press Ctrl/Cmd+K from anywhere in the panel and search open tabs, downloads, pins, quick access, recently closed, clipboard history, and notes at once - or jump straight to a section or run a quick action.
- Searches everything at once - tabs, downloads, pins, quick access, recently closed, clipboard, and notes.
- Jump to any section or run a quick action without leaving the keyboard.
- Arrow keys + Enter to navigate and select, just like a real command palette.
Type / and change any setting without touching the mouse.
The same command search doubles as a slash-command palette, autocomplete and all - Tab to complete, arrow keys to move between matches, Enter to run. Every quick action has its own zero-argument command, and every setting - theme, panels, widgets, auto-close, sync - has one too.
- One command per quick action - /pin, /tidy, /screenshot, and more.
- Settings commands for theme, panels, widgets, auto-close, screenshots, and sync.
- Terminal-style autocomplete - the palette suggests the next argument as you type.
Forty loose tabs, six labeled stacks.
See every open tab nested under its tab group - or a Pinned header - with live search. Group by site turns a scattered window into Chrome‑native tab groups (Gmail, Drive, Sheets, GitHub, YouTube…) without leaving the panel.
- Group tabs by site - one click sorts open tabs into real Chrome tab groups.
- Search as you type across every open tab, grouped or not.
- Ungroup all when you want your window flat again.
Your download history, without the download shelf.
Search, open, or show a file in its folder straight from the sidebar - or drag a completed download out to the desktop like it's already a file on disk.
- Drag‑out support - pull a finished download directly onto the desktop.
- Clear history in one click when the list gets long.
Two chips for the pages you never stop opening.
Save your go‑to pages as pins, then promote your top two to Quick Access chips that sit above everything else - Arc‑style, always one tap away, before the panel even loads.
- Pin current tab in one click from any page.
- 2 quick‑access slots pinned to the very top of the panel.
Your real Chrome bookmarks, not another list to maintain.
A dedicated panel for your actual bookmark tree - not a separate saved-links list. Bookmark or unbookmark the current tab in one click, run Tidy to dedupe and clear out empty folders, and move your whole tree to a new computer with one export/import.
- Live-searchable panel over your whole bookmark tree, always in sync.
- Tidy bookmarks - dedupe by URL and clear empty folders in one click.
- Export / import as a standard bookmarks HTML file, for moving between machines.
A scratchpad and a memory for everything you copy.
Notes auto‑save as you type, no save button, ever. Clipboard History quietly logs anything you copy on any page - click a past entry to copy it again, even after the tab that made it is long closed.
- Persistent scratchpad, synced across sidebar opens.
- Clipboard log with one‑click clear.
Whatever's making noise, always in view.
The Now Playing widget tracks whichever tab is (or was just) playing audio - live progress bar, pause, mute - even after you've switched away. Connect Spotify for full playback control and your playlists, right in the panel.
- Always‑visible widget, not buried in a tab list.
- Spotify playlists browsable without opening the app.
Twelve actions above the tab list, each one a single click.
Every action, panel, and widget in Sidebar Hub is individually toggleable in Settings - turn off everything you don't use and keep only the row of buttons you actually click.
Pin / unpin - Chrome's own native tab pinning, one click.
Archive - archive and close the current tab.
Tidy - group tabs by site and reorder in one pass.
Collapse - fold or expand every tab group.
Screenshot - capture the current tab to your chosen folder.
Pause all - mute every tab playing audio, at once.
Copy URLs - every open tab's link, one paste away.
Freeze - suspend background tabs and give memory back.
Export snapshot - write pins/notes/etc. to your sync folder.
Bookmark / Unbookmark - save or remove the current tab's bookmark.
Tidy bookmarks - dedupe and clear empty folders.
Open it, use it, gone.
