stemjson

Generative UI specification for native mobile: a declarative JSON language in which AI agents write a whole feature, its data, logic and navigation included, and the iOS and Android runtimes run it natively on SwiftUI and Jetpack Compose, offline.

Generative UI runtime for native iOS: checks a StemJSON module written by AI agents and builds it from real SwiftUI parts, with its data, logic and navigation, offline. Server-driven UI SDK for Swift, as a Swift package or XCFramework.

Example native Android apps whose features are StemJSON modules written by AI agents and run by the Kotlin runtime as real Jetpack Compose, with data, logic and navigation. Generative and server-driven UI you can clone and run.
