scriptc

scriptc compiles TypeScript and JavaScript into native executables and WebAssembly, with no JavaScript engine in the binary for statically typed code. It type-checks with the real TypeScript compiler, then generates machine code through LLVM. It's a Vercel Labs experiment under Apache 2.0.

Install with npm (Node 24+) or grab a standalone release; the compiler itself now runs natively on macOS, Linux and Windows. Building executables needs your platform's linker and SDK, like Xcode's command line tools on a Mac, plus zig for cross-compiling. Targets include macOS, Linux (glibc and musl), Windows, WASI, and iOS and Android static libraries. For npm dependencies and loosely typed code, a --dynamic flag embeds the QuickJS engine.

Free, no paid tier. Developers who want small, fast-starting CLIs from TypeScript should try it; it competes with Bun and Deno's compile commands and Node's single-executable apps, which ship a whole runtime inside the binary. Teams shouldn't bet production on it yet.

The catch: it's labeled experimental and supports only a subset of JavaScript, TypeScript and Node APIs, and it's moving fast, with v0.2.0 in September 2026 removing the old C backend entirely. Expect code that compiles today to need changes tomorrow.
