Perry Compiles TypeScript directly to executables using SWC and LLVM

No Runtime Required

Produces standalone native executables. No Node.js, no V8, no runtime dependencies. Just a single binary that runs anywhere.

Fast Compilation

Direct TypeScript to native code compilation using SWC for parsing and LLVM for optimized code generation. No intermediate JavaScript.

Small Binaries

Output binaries are typically 2-5MB. With optional V8 runtime for JS npm packages, 15-20MB. Ship less, deploy faster.

Deterministic Builds

Same input, same binary. Reproducible across machines, across CI runs, across teams. No mystery rebuilds.

Comprehensive Standard Library

Built-in native implementations of fs, path, crypto, os, Buffer, child_process, and more. Use familiar Node.js APIs.

Optional V8 Runtime

Need to use a pure JavaScript npm package? Enable the V8 runtime flag for full npm ecosystem compatibility.

25+ Native UI Widgets

Buttons, text fields, text areas, tables, canvas, scroll views, QR codes, secure fields, splash screens, and more — all compiling to real platform widgets via AppKit, GTK4, Win32, UIKit, and JNI.

Compile-Time Plugin System

Modules compose at build time — no runtime plugin overhead, no IPC boundaries. Your dependencies become direct native function calls in the final binary.

True Multi-Threading

Real OS threads with parallelMap, parallelFilter, and spawn. Compile-time safety rejects mutable captures — no SharedArrayBuffer, no workers, just threads.

Compile-Time i18n

Automatic string extraction, CLDR plural rules for 30+ locales, compile-time validation. Translations baked into the binary with near-zero runtime lookup.

Build & Sign

Cross-platform builds from one command. Code signing for macOS, iOS, Android, and Windows handled for you. No wrestling with Xcode provisioning profiles or Android keystores.

Distribute

Push to the App Store, Play Store, or ship direct downloads. Perry Publish handles packaging, notarization, and submission.

Verify

Powered by Geisterhand. Automated UI testing across all 6 platforms. Know your app works everywhere before your users tell you it doesn't.

// hello.ts
const greeting = "Hello, World!";
console.log(greeting);
// Compiles to ~2MB native executable
// No runtime needed!
