Simple. Fast. Efficient.

A self-hosting compiled language that produces native binaries under 200KB. The compiler, this website, and everything serving it — all written in Nyx.

Simple

Clean syntax. No hidden complexity. A language you can learn in a weekend.

Fast

Compiles to native code via LLVM. Fibonacci runs in 0.87x of C.

Efficient

Production binaries under 200KB. Zero external dependencies.

What Nyx looks like

// hello.nx
fn main() {
    print("Hello, World!")
}

// server.nx — HTTP server in 8 lines
import "std/http"

fn my_handler(request: Array) -> String {
    return http_response(200, "Hello from Nyx!")
}

fn main() {
    http_serve_mt(8080, 16, my_handler)
}
