Perry Compiles TypeScript directly to executables using SWC and LLVM

Everything you need to compile TypeScript to native applications

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.
