Key features
- Parallel install pipeline — Resolves, fetches and links packages in parallel for instant installs on a warm store.
- Content-addressable store — Keeps a single copy of each file on disk and hard-links it into every project.
- Workspace support — First-class monorepo handling with a single lockfile and filtered task execution.
- Catalogs — Define a dependency version once and reference it across the workspace to avoid version drift.
- Strict dependency isolation — Only declared dependencies appear in node_modules, preventing silent imports.
- Build script security — Install scripts run only for approved packages, reducing supply-chain attack surface.
- Patch dependencies — Apply persistent patches to packages without waiting for upstream fixes.
- Node.js runtime management — Pin and install specific Node.js versions per project without external tools.
Use cases

- Save disk space when managing dozens of projects with shared dependencies
- Enforce strict dependency declarations to avoid accidental imports
- Apply quick patches to third-party packages without forking
- Secure builds by blocking unapproved post-install scripts
