Perry is a powerful compiler that transforms TypeScript code directly into high-performance, native GUI and CLI applications for almost every major platform.

The main features of this tool include:

• Native Performance Without Runtimes: Unlike Electron or React Native, Perry produces standalone binaries with no Node.js, V8, or Electron runtime required. This results in 0 ms startup times and execution speeds up to 18x faster than Node.js.

• True Cross-Platform Support: A single codebase can be compiled into native apps for macOS, iOS, Android, Linux, Windows, watchOS, tvOS, and even WebAssembly/Web.

• Real Native UI Widgets: It uses 35+ native UI widgets (buttons, tables, charts, etc.) that compile directly to platform-specific frameworks like AppKit, UIKit, GTK4, and Win32 rather than using web views.

• Small Binary Footprint: Output binaries are typically only 2-5 MB, which is significantly smaller than the ~80-90 MB required for Node.js or Bun-based applications.

• Direct npm Integration: It supports popular packages like axios, zod, express, and fastify by compiling them into native code or using an optional embedded runtime for pure-JS packages.

• Advanced Developer Tools: It includes a built-in Git client, native multi-threading, compile-time i18n, and the Perry Publish suite for automated code signing and submission to the App Store and Play Store.

• Modern Compiler Architecture: It leverages SWC for ultra-fast parsing and LLVM for optimized machine code generation, bypassing intermediate JavaScript entirely.
