Which Package Manager? Explained

A decision guide that ranks npm, pnpm, Yarn (Berry), and bun against your project's real trade-offs.

Package managers trade speed, disk space, and compatibility against each other. Faster installs cost ecosystem familiarity. Lower disk use costs the node_modules norm. Answer five questions to find your winner.

Decision guide · 4 options

The options

npm

The default. Ships with Node. Works everywhere.

Maximum ecosystem compatibility and zero setup. The safe baseline for any stack.

pnpm

Fast installs from a content-addressed store.

Monorepos and large workspaces. One shared store cuts disk across every project.

Yarn (Berry)

Workspaces, Plug'n'Play, and mature monorepo tooling.

Teams already on Yarn. PnP removes node_modules entirely.

bun

One runtime, installer, and bundler. Fastest cold installs.

Greenfield projects that want a single tool end to end.
