Arcmark - macOS용 브라우저 사이드북마크 관리자

Arcmark demonstrates how innovative browser features can escape vendor lock-in through open-source implementation, allowing Arc's signature sidebar design to enhance any browser while maintaining offline-first privacy. This signals a growing user expectation for cross-browser feature parity and transparent, locally-controlled bookmark management rather than cloud-dependent synchronization. The tool exemplifies how native macOS integration can provide seamless multi-browser support without sacrificing performance or user autonomy.
