Features
- Written in Rust for maximum performance
- Automatic dependency detection from source code
- Built-in toolchain management (Node, Bun, Deno)
- Project-level configuration with inheritance
Pros
- Fastest monorepo tool due to Rust implementation
- Manages toolchain versions automatically
- Language-agnostic design supports polyglot repos
Cons
- Smallest community among monorepo tools
- Fewer integrations than Nx or Turborepo
- Requires learning moon-specific configuration format
Overview
moon is a repository management and build orchestration tool written in Rust. It is designed to handle monorepos at scale with a focus on performance, correctness, and developer experience. Unlike Turborepo and Nx which layer on top of existing package managers, moon takes a more opinionated approach by managing the entire development workflow.
A standout feature of moon is its built-in toolchain management. It can automatically download, install, and manage specific versions of Node.js, Bun, and other runtimes, ensuring every developer on your team uses the exact same versions without manual setup.
moon also automatically detects dependencies between tasks by analyzing source code imports, reducing the amount of manual configuration needed compared to pipeline-based approaches.
When to Use
Choose moon for polyglot monorepos where you want a single tool to manage both the build pipeline and the development toolchain. It is ideal for teams that want maximum performance and are willing to adopt moon’s opinionated workflow.
Getting Started
npm install -g @moonrepo/cli
moon init
moon run :build
