Question 1

What is SupaSidebar most similar to?

Accepted Answer

SupaSidebar is closest to Arc Browser's sidebar, but it works as a separate Mac app instead of a browser. That means you keep your existing browser - Safari, Chrome, Firefox, Brave - and get an Arc-style sidebar that spans all of them at once.

Question 2

What's the best Arc Browser alternative for Mac?

Accepted Answer

After Arc entered maintenance mode, SupaSidebar became the closest replacement for Arc's sidebar and spaces while letting you keep using Safari, Chrome, or any other browser. See the full comparison at /compare/arc-browser.

Question 3

Is SupaSidebar a tab manager, a bookmark manager, or a browser?

Accepted Answer

SupaSidebar isn't a browser. It's a layer that sits on top of the browsers you already use - Chrome, Safari, Arc, whatever. It does three things at once: tracks your open tabs across every browser, like a tab manager (Toby, OneTab); organizes saved links into spaces and folders, like a bookmark manager (Raindrop, Pocket); and unifies browsing history across browsers, like a sidebar browser (Arc, Zen). That's why it shows up in comparisons with all three - and for most people, it replaces the tab manager and bookmark manager entirely. The one thing it doesn't replace is your browser.

Question 4

How does SupaSidebar compare to Workona?

Accepted Answer

Workona is a Chrome-only workspace extension. SupaSidebar is a native Mac app that works across every browser at the same time, including Safari and Firefox, and adds file and app launching alongside tabs. Workona is a better fit if you only ever use Chrome, on any operating system.

Question 5

Does SupaSidebar replace my browser?

Accepted Answer

No. SupaSidebar runs alongside your existing browsers. You can keep Safari for personal browsing, Chrome for work, and Firefox for testing - SupaSidebar shows tabs from all of them in one sidebar.

Question 6

Why use SupaSidebar instead of a Chrome extension?

Accepted Answer

Chrome extensions only work inside Chrome. SupaSidebar is a Mac app, so it works across every browser at once and survives browser restarts, profile switches, and even browser changes. If you switch from Chrome to Arc or Safari, your SupaSidebar setup follows you.

Question 7

Which comparison should I read first?

Accepted Answer

Start with the comparison that matches your current setup. If you came from Arc, read /compare/arc-browser. If you have tab overload in Chrome, read /compare/tab-managers. If you want better bookmarks, read /compare/bookmark-managers.
