Hey HN — I've been building Perry, a compiler that takes TypeScript and emits native binaries. No V8, no runtime, no Electron. It maps to platform-native UI widgets: AppKit on macOS, UIKit on iOS, Android Views on Android, GTK4 on Linux, Win32 on Windows.

Pry is the first real app built with it — a JSON viewer, deliberately small.

It's in the iOS/macOS App Store and Google Play right now. Linux build works, Windows is waiting on code signing.

The compiler itself is written in Rust. It handles TypeScript parsing, type checking, and lowers to native code. The UI bindings aren't a wrapper library — the compiler generates the actual platform API calls.

This is a building-in-public thing. Pry is the proof-of-concept. The bigger goal is a full IDE. Happy to answer questions about the compiler architecture, the app store submission process, or anything else.
