A native macOS browser built with SwiftUI and WebKit, with an iPhone and iPad companion.
- Runs Chrome and Safari WebExtensions: add them from the Chrome Web Store with Add to Browser in the address bar, from a ZIP, CRX, or folder, or from Safari extensions in your apps (Settings ▸ Extensions).
- Tells sites that turn away unknown browsers that it's Chrome or Firefox (View ▸ Website Compatibility), and opens pages that need another engine in another browser (View ▸ Open Page In).
- Syncs each profile's bookmarks and open tabs through iCloud with your other Macs, iPhone, and iPad, and hands pages off to them.
- macOS 15.4 or later; iOS and iPadOS 18.4 or later
- Xcode 26 or later
- XcodeGen

The iPhone and iPad app is the BrowserMobile scheme. iCloud sync needs a build signed with BROWSER_ICLOUD=YES
(see RELEASING.md); other builds work without it.
