MoYu - Cross-Platform Visual Novel Engine

简体中文 | English | 日本語

A progressive cross-platform visual novel engine with a Rust core, using browser-independent React to build interfaces and presentation.

Built for modern visual novel development, Moyu combines a Rust core with a JS/React development workflow, offering creators a progressive experience from rapid prototyping to deep customization.

Features

• Consistent cross-platform support: Runs on Windows, macOS, Linux, Android, iOS, and Web — write once, run everywhere.
• Multiple graphics backends: Switch between Vulkan / Metal / DX12 / OpenGL.
• Highly customizable interfaces: Use React to build any UI and system, reusing the mature ecosystem's resources and tooling.
• Progressive and flexible: From the standard framework to deep extensions in the Rust layer, complexity is unlocked step by step.
• Open source and business-friendly: Licensed under MPL-2.0 — free to use, including for commercial projects.

Layered Architecture

• Rust layer: Resource management / graphics rendering / audio system / native plugins.
• JavaScript layer: React components / story logic / animation orchestration.

Repository Structure

• crates/ — The Rust engine core, runtime, nodes, platform abstraction, and more.
• packages/ — Upper-level JavaScript / TypeScript: @momoyu-ink/kit (React SDK), @momoyu-ink/cli (CLI), and more.
