Questions
Coming from Arc?
Import in one step: spaces, pinned tabs, folders, splits, history and passwords. Right on the first screen, or File → Import from Arc…
Why Safari's engine?
WebKit is the engine Safari uses, and it's already on your Mac. Sapfire doesn't ship a second Chromium — that's why it is small, light on memory and kind to your battery.
Do my extensions work?
Most do. Sapfire installs them from the Chrome Web Store and Firefox Add-ons; a few use features Safari's engine doesn't have. Requires macOS 15.4 or later.
Is it safe to open?
Yes — signed with a Developer ID and notarized by Apple, so macOS opens it without warnings. And the code is open: read every line.
Does it sync between Macs?
Not yet.
Windows? iPhone?
Mac only, for now.
