Hypen is a crossplatform framework for building and streaming native UI across web, desktop, and mobile. Apps stream UI from a backend into a client so changes deploy instantly, and any app embedding the Hypen SDK can render apps inside apps, build backend-driven features, or create mini-app platforms like WeChat. It supports many languages including TypeScript, Rust, Go, Kotlin, Swift, and anything that can run WASM or interop with native. Recent features include first-class accessibility support, animation support, a video component with a Netflix clone example app, and a UI testing suite for previewing apps across devices; upcoming features include exposing states and actions to agents so they can drive apps directly, drag-and-drop with pinning, device communication and permissions, Android TV support, theming, and external component installation.
