Claude Island

A native macOS app (SwiftUI + AppKit) attached to the MacBook notch, or the top edge on displays without one, that monitors Claude Code sessions through the documented hook protocol: it surfaces session, tool and nested-subagent activity, answers questions and permission requests straight from the Island, tracks multiple concurrent terminals and returns focus to the terminal that started the work. Ghostty, Terminal, iTerm2 and Warp integration, five-hour and weekly Claude usage, configurable idle hiding and signed Sparkle updates. No project-operated backend or telemetry. Requires macOS 14 Sonoma or later. Source-available; the official download ships only after Developer ID signing and Apple notarization.
