KARN v1.0.0 — The Agent's Language

First Release

A token-minimal, platform-agnostic programming language designed specifically for AI agents.

Why KARN?

AI agents are writing code in languages designed for humans. Python, TypeScript, Rust—all optimized for readability. But agents don't need readability—they need token efficiency, deterministic execution, and multi-platform output from a single source.

KARN delivers:

  • 76% fewer tokens than Python for equivalent logic
  • 3 codegen targets — C (native binary), JavaScript (Node.js), Web (HTML), Python
  • Error as value — no exceptions, every I/O returns Ok|Err
  • Full stdlib — http, fs, log, env, json, math, time, str, crypto, db
  • Ecosystem interop — from pip, from npm, from cargo, from sys

Quick Demo

# Install
pip install karn-lang

# Run
echo '! "Hello from KARN"' > hello.kn
karn run hello.kn
# → Hello from KARN!

# Compile to C → native binary
karn build hello.kn --target c
gcc -o hello hello.c -lm
./hello
# → Hello from KARN!

# Same source, JavaScript
karn build hello.kn --target js
node hello.js
# → Hello from KARN!

What's Built

  • Interpreter: Full tree-walk evaluator with REPL
  • JIT Mode: Profiles hot functions, compiles to native on-the-fly
  • C Codegen: Outputs C source → gcc/clang → native binary
  • JavaScript Codegen: Outputs Node.js-compatible JS
  • Web Codegen: Outputs self-contained HTML
  • Python Codegen: Outputs portable Python 3
  • 91 tests passing across lexer, parser, interpreter, codegen

For Agents

KARN is designed to be consumed by agents, not just used by them:

Install

pip install karn-lang
npm install karn-lang
