TypeScript × Native

TypeScript at the speed of C.

Same syntax you already write — now compiled to native binary. Watch the intro

Why MetaScript exists

Every time tsc runs, your types get thrown away. Without them, even the fastest JS engine has to figure out your code as it runs — that's the runtime ceiling. MetaScript keeps the types and compiles them to native code. Same syntax, no ceiling. Read the full story

What it looks like

Same syntax. Compile to anywhere.

Native-tier performance

Here's what “no ceiling” looks like in numbers. MetaScript lands in the native tier — alongside C and Rust.

In production

Under Realm , a live Trading Card Game, runs parts of its TypeScript backend on MetaScript today. It's from our own games studio — we use what we build.

What just works

Open it in VS Code, JetBrains, Zed, or Neovim. Set up your editor
Run it on Mac, Linux, or Windows. Install
Build it for all of them from one machine. CLI reference

What's still rough

MetaScript is in beta. There's still a lot to build:

The standard library is thin. Reference docs
The package registry is almost empty. Browse it
Error messages need work.

These aren't surprises — they're what comes next when a proof of concept grows into a real tool. The compiler is ready to install today ; source opens July 1, 2026 .

Write your first MetaScript.

MetaScript is in beta. Install the compiler and write your first native TypeScript program tonight, or try it first in the Playground .
