The foundation
An open-source compiler, typed language, and native & WASM targets.

Wosy is a language for what comes next.
Open source. Built in the open. Yours to explore.

%%endTHE LANGUAGE
A fresh start for software,
one line at a time.
A small, typed language with a native compiler. Familiar enough to start reading. Deliberate enough to build on.
Clear types, functions, and control flow keep the structure in view.
LLVM-backed compilation targets native binaries and WebAssembly.
Read the compiler, inspect the build, and follow the work on GitHub.

a little language.WHY WOSY EXISTS
Agents can already generate software. The next challenge is making that software dependable.
Wosy starts with the language itself: a foundation where agents can build, reason about their work, and move toward stronger guarantees.
The goal? Software without bugs.
