moon

moon is a task runner and monorepo management tool specifically designed for web development ecosystems. It helps development teams manage complex codebases with multiple interconnected projects by providing a unified system for running tasks, managing dependencies, and coordinating builds. Written in Rust for performance, it works across Linux, macOS, and Windows platforms.

The tool uses smart hashing to track inputs and outputs, ensuring builds are deterministic and reproducible. It features remote caching to persist build artifacts between development environments and CI/CD systems, reducing redundant work. moon automatically handles toolchain management, downloading and installing the correct versions of languages and tools needed for each project. It generates dependency graphs to optimize task execution order and runs tasks in parallel where possible.

moon benefits development teams working with monorepos containing JavaScript, TypeScript, Rust, Go, Ruby, and other web technologies. It's particularly useful for teams that need consistent builds across developer machines and CI environments, want to reduce build times through caching, and need to manage complex interdependencies between multiple projects in a single repository.
