Zuki

An async runtime for Zig, inspired by Tokio

⚠️ Pre-Alpha - Early Development

Zuki is a high-performance async runtime for Zig that aims to provide zero-cost abstractions for asynchronous programming. The name "zuki" (月 - moon in Japanese) represents a reliable foundation for async applications.

Status

This project is in very early development. APIs are experimental and will change frequently. Not ready for production use.

Goals

• Zero-cost async abstractions
• Memory safety through Zig's compile-time guarantees
• Cross-platform support (Linux, macOS, Windows)
• Deterministic performance for real-time systems

Architecture

• Work-stealing multi-threaded scheduler
• Platform-optimized I/O (io_uring, kqueue, IOCP)
• Hierarchical timer wheel
• Configurable memory allocation strategies

Building

zig build
