Voyd

Voyd is a language for building WebAssembly programs with a small surface area, strong type checking, and a runtime model that stays close to the generated code.

fn fib(n: i32) -> i32
  if n < 2:
    n
  else:
    fib(n - 1) + fib(n - 2)

pub fn main() -> i32
  fib(10)

Design goals

• Read like a high-level language.
• Compile like a systems language.
• Keep package boundaries and effects explicit.
• Make macros, traits, and Wasm-facing code practical instead of ornamental.

Start here

• Basics
• CLI
• SDK
• Syntax
• Functions
• Control Flow
• Modules
• Types Overview

Feature map

• Structural and nominal types.
• Traits with default methods.
• Algebraic effects with typed handlers.
• Macros for surface-language features such as enum and for.
• A package/module system built around src/ and pkg.voyd.

Installation

npm i -g @voyd/cli

The installed command is voyd. When working inside the Voyd repository after npm link, the vt command points at the development CLI entrypoint.
