Overall
Why choose SupaSidebar over Vivaldi’s sidebar
A sidebar that works across all your browsers, not locked to one.
Works with every browser
Vivaldi’s sidebar only works inside Vivaldi. SupaSidebar works alongside Safari, Chrome, Firefox, Brave, and Vivaldi itself. One sidebar for all of them.
Native macOS performance
Built with Swift and SwiftUI, not Chromium. SupaSidebar uses a fraction of the RAM and integrates deeply with macOS - Spotlight, Finder, iCloud.
Search tabs across all browsers
Vivaldi’s Quick Commands only search Vivaldi tabs. SupaSidebar’s Command Panel searches tabs from every open browser, plus bookmarks, files, and apps.
More than web panels
Vivaldi’s sidebar holds web pages. SupaSidebar holds files, folders, apps, and links. Drag anything from Finder into your sidebar.
Frequently asked questions
Can I use SupaSidebar with Vivaldi?
Yes. SupaSidebar works with Vivaldi and every other browser. You get SupaSidebar’s cross-browser features on top of Vivaldi - pinned items, spaces, command panel, and live tabs from all your browsers.
Is Vivaldi better than Chrome?
Vivaldi offers more customization than Chrome - vertical tabs, built-in mail, web panels, and ad blocking. Both use Chromium under the hood. If you want sidebar features without switching browsers, SupaSidebar adds them to Chrome, Vivaldi, or any browser.
Does Vivaldi use a lot of RAM?
Vivaldi is Chromium-based, so RAM usage is similar to Chrome. SupaSidebar is a native macOS app built with Swift - it uses significantly less memory since it’s not running a full browser engine.
Does SupaSidebar replace my browser?
No. SupaSidebar is not a browser. It’s a native macOS sidebar app that works alongside any browser. Keep using Vivaldi, Chrome, Safari, or whatever you prefer.
Is SupaSidebar free?
SupaSidebar has a free tier with 3 spaces and all core features. Pro unlocks unlimited spaces, iCloud sync, and early access to new features.
