A build system for the JavaScript ecosystem

Smart hashing
Experimental
Collects inputs from multiple sources to ensure builds are deterministic and reproducible.
Remote caching
Coming soon
Persists builds, hashes, and caches between teammates and CI/CD environments.
Integrated toolchain
Automatically downloads and installs explicit versions of Node.js and other tools for consistency.
Multi-platform
Runs on common development platforms: Linux, macOS, and Windows.

Project graph
Generates a project graph for dependency and dependent relationships.
Project boundaries
Enforces boundaries to eliminate cycles and reduce indirection.
Dependency workspaces
Works alongside package manager workspaces so that projects have distinct dependency trees.
Ownership metadata
Declare an owner, maintainers, support channels, and more, for LDAP or another integration.

Dependency graph
Generates a dependency graph to increase performance and reduce workloads.
Action runner
Executes actions in parallel and in order using a thread pool and our dependency graph.
Action distribution
Coming soon
Distributes actions across multiple machines to increase throughput.
Incremental builds
Experimental
With our smart hashing, only rebuild projects that have been touched since the last build.

Flakiness detection
Experimental
Reduce flaky builds with automatic retries and passthrough settings.
Webhook events
Coming soon
Receive a webhook for every event in the pipeline. Useful for metrics gathering.
Terminal notifications
Coming soon
Receives notifications in your chosen terminal when builds are successful... or are not.

Integrated packages: In development
Enhance your pipeline with our @moonrepo npm packages.
Node.js inspection: Coming soon
Inspect and debug failing Node.js processes.
Build profiles: Coming soon
