Sifr: Python Syntax That Compiles to Fast Rust Binaries

Sifr is a compiled language that lets you write familiar Python-style code and get native Rust performance in return. If your Sifr program compiles, it works — the compiler enforces static typing, safe error handling, and ownership before a single line of your code ever runs.

Get up and running in three steps

Install Sifr

Run the official installer script to download a prebuilt binary for your platform, verify its checksum, and add sifr to your shell’s PATH.

curl -fsSL https://sifr.sh/install | sh

Write your first .sifr file

Create a file called hello.sifr and add a main function. Sifr uses Python syntax, so if you know Python, you already know the basics.

hello.sifr

def main():
    print("Hello from Sifr!")

Run it

Use sifr run to compile and execute your program in a single command. When you are ready to ship, sifr build produces a standalone native binary.

sifr run hello.sifr
