SuperIsland Alternative: Go Native, Not Electron
SuperIsland wraps a web runtime around your notch: in our idle-CPU benchmark it consumed roughly 5× the CPU of native notch apps, taxing your battery all day. Notchy is 100% native SwiftUI — ~0% idle CPU, buttery ProMotion animations, and every feature SuperIsland has plus 30 more, for $0.
Why use Notchy instead of SuperIsland?
- Native SwiftUI vs Electron
Our published benchmark (Apple M2, macOS 26.5) measured SuperIsland at ~0.46% idle CPU versus ~0% for Notchy. A web runtime never sleeps; native code does. Your battery notices.
- A fraction of the memory
Electron apps ship an entire browser. Notchy is a ~50 MB native app tuned for Apple Silicon with near-zero RAM and no helper processes churning in Activity Monitor.
- More features, zero dollars
Clipboard history, file shelf, Pomodoro, synced lyrics, AI usage tracking, command palette, HUD replacement — all free, no account, no subscription.
