Lona is a collection of tools from Airbnb for defining design systems in a JSON-based component format and generating cross-platform UI code, Sketch files, and other artifacts. It includes Lona Studio, a native macOS GUI for designing components, and Lona Compiler, a CLI for generating Swift and React code.

Use cases

  • generate cross-platform UI code from a design system
  • design components visually in a mac app
  • export design system to Sketch files
  • mock up app screens from existing components
  • preview designs with real JSON or API data
  • localize and export screenshots automatically

When to choose

  • you maintain a design system shared across iOS and React platforms
  • you want a single source of truth for components, colors, and text styles
  • you need to generate Swift or React UI code from component definitions

When to avoid

  • you need Android/Kotlin code generation today
  • you require well-documented, production-hardened tooling
  • you don't work on macOS, since Lona Studio is a Mac app
