Hey HN! I was very early adopter of Arc. as a dev, I enjoyed useful shortcuts (like copy URL), vertical sidebar, command panel, and other cool features. when TheBrowserCompany left Arc, i also switched browsers but missed all those cool features. so I decided to make Arc’s features universal.

Meet SupaSidebar - Arc-like sidebar for all browsers

Here’s what the app can do: - Save links, files, and folders from any browser or Finder - Fuzzy search current open tabs, browser history, and saved links - Open saved links in any browser with just a click - Common browser history across browsers - iCloud sync - Link browser profiles to Spaces and quickly switch between them - Built-in sidebar feel with fullscreen, overlay protection, auto show/hide etc. - Global shortcuts, Air Traffic Control, AI tagging, and more

here's a demo video: [SupaSidebar Demo](https://youtu.be/OimIUO0PSAk)

Free to use for up to 3 Spaces. Native Swift/AppKit, no Electron.

Still in development and I’m making it better daily, so any feedback would be appreciated.
