Changelog

A proper welcome, and a way over from Arc and Dia

• Bring everything over from Arc: your spaces with their colours and icons, pinned tabs, folders, Today and history, in one go. Arc gets a sunset on its way out. File ▸ Import from Another Browser…
• Bring your pinned tabs, folders and history over from Dia, into a space of their own.
• A new first launch: Sill sets itself up with you at a window. Bring your things, make your first space yours, and learn the gestures by trying them on your trackpad.
• Gesture hints: when you do something the slow way, Sill shows you the gesture for it. Switching tabs, spaces and folders, opening the Overview, and going back or forward.
• Delete folders and spaces: right-click one in the Overview, or use the Spaces menu. A folder's tabs can stay, in Today.
• A sweep of warm light rises through the window when Sill opens onto an empty space.

The first public version

A calm, native Mac browser that keeps out of the way of the page.

• A floating Liquid Glass bar that rests out of the way while you read and comes back when you need it.
• Spaces, folders, pinned tabs and kept tabs, with an Overview of everything you have open. Pinch to see it.
• Swipe between tabs, and swipe back and forward through a page's history. Hold to pick from the list.
• Spotlight for new tabs, plus Peek and Small Sill for links you only need for a moment.
• Split View, Air Traffic Control, multiple windows, profiles and private windows.
• Built-in ad and tracker blocking.
• Picture in picture for videos and calls, and a floating audio player, controlled with pinch and two-finger gestures.
• Passwords: fill from a menu under the field (including sign-ins inside frames), strong passwords for new accounts, Touch ID, and import from a CSV.
• Sleeping tabs to keep memory low, and a hover card showing each tab's memory.
• Updates download quietly and install when you quit, or now with Relaunch.

Requires macOS 26 Tahoe on a Mac with Apple silicon.
