Safari is Apple's proprietary default browser for macOS and iOS, built on the open source WebKit engine but closed source itself and unavailable outside Apple platforms. Full details →

Switching from Safari to an open source alternative gives you a browser that isn’t tied exclusively to Apple hardware and whose full application code, not just the underlying engine, is publicly auditable. Firefox runs on its own independent Gecko engine and is available on Windows and Linux as well as macOS, useful for anyone who splits time across platforms. Brave stays closer to Safari’s WebKit lineage in spirit — both trace back to the same KHTML/WebKit origins — while running on Chromium/Blink today, with ad and tracker blocking built in by default. LibreWolf hardens Firefox’s own privacy settings further for users who want the strictest defaults out of the box. Tor Browser takes a different approach again: built on Firefox ESR and maintained by The Tor Project, it routes traffic through the Tor network for anonymity and censorship circumvention, a distinct use case from the faster, still-identifiable browsing the other three aim for, and one that trades speed and some site compatibility for that anonymity. None replicate Safari’s Handoff continuity across Apple devices, but all are free, open source, and available beyond the Apple ecosystem.
