SupaSidebar is a Mac sidebar app that unifies bookmarks, open tabs, and browser history across Safari, Chrome, Firefox, Arc, and other browsers into one vertical panel.
What is SupaSidebar?
SupaSidebar is a macOS app (requires macOS 14+) that replaces each browser's separate bookmark and tab management with a single sidebar. It connects to all installed browsers on your Mac, reads their open tabs and bookmarks, and displays them in one list. Created by developer Kshetez (GitHub: auspy, X: @kshetezvinayak), the app runs as a persistent panel on the left side of the screen — not inside any browser.
Key Features
- Unified tab view — See every open tab from Safari, Chrome, Firefox, Arc, Brave, and more stacked vertically in one sidebar; click any tab to jump to it in its source browser.
- Quick-Save bookmark shortcut — Save any tab as a bookmark from any browser using a single keyboard shortcut; no browser extension required.
- Spaces and folders — Organize bookmarks and tabs into named workspaces (e.g. Work, Personal, Dev Projects) with nested folders; free plan includes 3 spaces, Pro and Lifetime give unlimited spaces.
- Command Panel — Fuzzy-search across open tabs, bookmarks, browser history, folders, and spaces from one panel (Spotlight-style).
- iCloud sync — Sync bookmarks and spaces across all your Macs automatically via iCloud (stated by user Ronald Epstein).
- Send page to another browser — One-click "Open in Browser" action to move the current page from any browser to any other browser on your machine.
- Recents tab — Shows all recently visited tabs from every browser in one chronological list.
Who is it for?
- Multi-browser users — People who use Safari for personal, Chrome for work, and maybe Firefox or Brave for testing; SupaSidebar consolidates their bookmarks and tabs into one place.
- Former Arc users — Users migrating away from Arc who want to keep Arc's vertical tab and space workflow across other browsers (testimonial: "helped me migrate away from Arc").
- Web developers — Developers who test sites across multiple browsers and need to quickly open the same page in a different browser without copy-pasting URLs.
- Project-based workers — Anyone who maintains separate workspaces (e.g., client sites, research, local dev) and wants to switch between context-specific sets of bookmarks and open tabs.
What can you do with SupaSidebar?
- Manage bookmarks from one place: Import existing bookmarks from any browser, then save new ones using a global shortcut. All bookmarks live in SupaSidebar's folders and sync via iCloud.
- View all open tabs in one list: Instead of switching between browser windows, see every open tab from every browser in a single vertical scrollable list.
- Search across browser history: Use the Command Panel to fuzzy-search history from all browsers, not just the one you're currently using.
- Organize work vs. personal: Create separate Spaces for work projects, study, research, and hobbies, each with its own set of folders and bookmarks. Switching Spaces hides irrelevant tabs.
