RGC is the native compiled language for Python developers.

Fast. Safe. Familiar.

For Linux, macOS, and Windows

Fast

Compiles to native machine code.

The LLVM backend compiles RGC to local code — no interpreter, no GC, performance on par with C / Rust.

terminal

$ rgc hello.rg -o hello
$ ./hello
» Hello, RGC!

Memory safety without GC.

Ownership and borrow checking rule out dangling references and data races at compile time — safety holds before your program ever runs.

borrow.rg

def length(s: @str) -> int {
    return s.len()
}

def main() {
    text = "RGC"
    print(length(@text))
    print(text)
}

The syntax Python developers know.

def, if, for, and # comments — Python developers write RGC on day one.

examples/fib.rg

def fib(n: int) -> int {
    if n <= 1 {
        return n
    }
    return fib(n - 1) + fib(n - 2)
}

def main() {
    print("fib(10) =", fib(10))
}

Monomorphized compilation — abstractions with no runtime cost.

List, str, Maybe, and Result out of the box.

The compiler is written in RGC itself — the ultimate test of expressiveness.

One command to install.

terminal

$ curl -fsSL https://rgc-dev.tensorplay.cn/install.sh | sh
$ rgc --version
RGC 0.1.0
$ rgc hello.rg -o hello && ./hello
» Hello, RGC!
