AI-native systems language

Compact source. Native binaries. Built for agents.

Ax is a preview programming language for extreme code compression, explicit semantics, native execution, and small tools that humans and AI agents can inspect quickly.

Start

Install, run, and ship compact Ax programs.

Prebuilt binaries are published for macOS arm64/x64, Linux x64/arm64, and Windows x64. Release binaries embed the standard pack manifests and runtime sources for standalone installation.

Compact Source Is The Surface

Ax source is authored directly in parser-checked AI-min form. The compiler, formatter, examples, tests, docs, and agent skill all treat compact `.ax` as the source of truth.
