A lightweight and fast JavaScript-To-EXE compiler

Features

• A lightweight tool that compiles JavaScript/TypeScript-based applications into a single executable (.exe)
  • Especially targets CLI tools and server apps (Express, Fastify, etc.) (not meant as an Electron alternative)
• Uses a compilation approach completely different from the existing pkg and nexe. Also works around the limitations of Node.js SEA
• Built on esbuild, so compilation is very fast; average output size is 70–80MB, reduced to around 30MB with upx
• Supports the latest Node.js versions and ESM modules
• Executable metadata such as icon, name, and version information can be customized, with an excellent developer experience
• Currently Windows only; macOS and Linux support is in development
