Cra

Cra is a free and open-source web browser for macOS built as a one-to-one replacement for Arc. It keeps Arc's sidebar-based workflow, with spaces that each have their own favorites, pinned tabs, Today list and colour, and lets you import your Arc spaces, pinned tabs, folders, favorites, archive, passwords and extensions in one step.

It includes a command bar that searches open tabs, history, the archive and app actions, Today tabs that archive themselves after a set time, a Library for media, downloads and archived tabs, Split View with up to four panes, Little Windows for links opened from other apps, Peek, automatic Picture in Picture, Air Traffic Control, Live Folders, per-space profiles and Arc's keyboard shortcuts.

The app is written in Swift (AppKit and SwiftUI) and uses Chromium through the Chromium Embedded Framework, so websites and Chrome extensions work as they do in Chrome. Optional tab and download tidying runs on-device with Apple Intelligence, and the browser has no ads.
