Open source build tool for monorepos and large codebases
moonrepo is a developer tool that reduces build/test/deploy times, and maintenance costs for companies. We’ve achieved this through moon, our open source build system and repository management tool. moon can be paired with moonbase, our paid service that provides cloud caching, CI insights, code ownership, and health score related metrics. The company is founded by Miles Johnson and James Pozdena who have a combined 25+ years in the software development industry with tenure at Airbnb and Coinbase.
moonrepo is a developer productivity tooling platform designed to manage codebases and monorepos across multiple languages. It emphasizes efficient task orchestration, project organization, and consistent environments from build to deploy.
Moonrepo offers a monorepo build system, a multi-language version manager (proto), and an integrated toolchain to spin up development environments with consistent tools and versions. It features smart task hashing, robust caching, and efficient task execution to avoid repeating work, along with centralized project ownership, language/version management, and a light-speed interface built on a Rust foundation.
Who it’s for: Developers and engineering teams working with large or multi-project codebases and monorepos across multiple languages who want faster builds, consistent environments, and better project organization.

I'm very passionate about developer tooling and the developer experience. With 15 years of industry experience under my belt working across the entire web stack, I enjoy testing my skills and knowledge against complex problems, but what I really love is supporting my fellow peers by building solutions to improve their developer experience and productivity.
From build to deploy, moonrepo is a better way to manage codebases, save developer time, and boost your business.
Moonrepo launches a language-agnostic task runner and upstream CI monitoring service for users with monorepos or large codebases. It aims to reduce build and CI times by running tasks only on affected changes, offering YAML-based configuration, automated workflows, and a free/open-source moon task runner plus a free-tier moonbase service for project health and CI monitoring.
