Litho is a declarative UI framework from Facebook for building efficient Android user interfaces using immutable components and a functional render API. It optimizes performance through asynchronous layout, view hierarchy flattening via Yoga, and fine-grained recycling of individual UI elements.

Use cases

  • build efficient scrollable UIs on Android
  • declarative UI framework for Android apps
  • reduce view hierarchy depth for better scroll performance
  • recycle individual UI components in long lists
  • build complex RecyclerView-based feeds
  • measure and layout UI off the main thread

When to choose

  • building complex, highly-optimized scrollable Android UIs like feeds or timelines
  • you need asynchronous layout and fine-grained recycling for performance
  • your team prefers a declarative, React-like component model on Android

When to avoid

  • building simple Android apps where Jetpack Compose or standard Views suffice
  • you want a large community ecosystem and frequent third-party libraries
  • your team works primarily in Java with the legacy Spec API and wants modern Kotlin-first tooling
