Brow (Why We Built Brow in Swift, Not Electron)

Brow was built as a native Swift app instead of using Electron because deep macOS system integration—window management, clipboard, hardware stats, accessibility hooks—requires direct access to native frameworks. The article contrasts this with Raycast's approach of a native core with a React/TypeScript extension ecosystem, arguing that while web-based extensions boost ecosystem growth, they introduce mediation overhead that conflicts with tight system-level product design.
