Core strengths

Why choose H#?

Peak performance

Optimized with an LLVM backend for C++-class speed, while keeping the convenience of a high-level language.

Memory safety

A unique ownership model eliminates data races and null-pointer exceptions at compile time — no garbage collector required.

A rich ecosystem

Built-in package manager `hpm` — install dependencies in one step.
