Perry — TypeScript → Native

v0.5.306 — generational GC + lazy JSON tape default, faster than Node and Bun on most benchmarksOne Codebase. Every Platform.Native Performance.Perry compiles TypeScript to native GUI and CLI apps on macOS, iPadOS, iOS, Android, Linux, Windows, watchOS, tvOS, WebAssembly, and the Web. No runtime. No Electron. Just native binaries.Get StartedView on GitHubterminal$ perry compile main.tsCompiling main.ts...✓ Compiled executable: main (2.3 MB)$ ./mainHello, World!10Targets25+Native UI widgets0 msStartup timeApp StoreReadyWhy Perry?Everything you need to compile TypeScript to native applicationsNo Runtime RequiredProduces standalone native executables. No Node.js, no V8, no runtime dependencies. Just a single binary that runs anywhere.Fast CompilationDirect TypeScript to native code compilation using SWC for parsing and LLVM for optimized code generation. No intermediate JavaScript.Small BinariesOutput binaries are typically 2-5MB. With optional V8 runtime for JS npm packages, 15-20MB. Ship less, deploy faster.Deterministic BuildsSame input, same binary. Reproducible across machines, across CI runs, across teams. No mystery rebuilds.Comprehensive Standard LibraryBuilt-in native implementations of fs, path, crypto, os, Buffer, child_process, and more. Use familiar Node.js APIs.Optional V8 RuntimeNeed to use a pure JavaScript npm package? Enable the V8 runtime flag for full npm ecosystem compatibility.25+ Native UI WidgetsButtons, 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 SystemModules compose at build time — no runtime plugin overhead, no IPC boundaries. Your dependencies become direct native function calls in the final binary.True Multi-ThreadingReal OS threads with parallelMap, parallelFilter, and spawn. Compile-time safety rejects mutable captures — no SharedArrayBuffer, no workers, just threads.Compile-Time i18nAutomatic string extraction, CLDR plural rules for 30+ locales, compile-time validation. Translations baked into the binary with near-zero runtime lookup.
