Quick verdict: pnpm is faster, saves disk space, and handles monorepos better. npm wins on familiarity and zero-setup since it ships with Node.js. For any team or project beyond a simple hobby app, pnpm is the better choice. pnpm wins 7-5 across our 12 criteria.
Our Verdict
npm
- Pre-installed with Node.js -- zero setup
- Every tutorial and readme uses npm
- Largest registry (2.5M+ packages)
- Slower installs than pnpm
- Duplicates packages across projects
- Phantom dependency issues
pnpm
- 2-3x faster installs than npm
- Saves gigabytes of disk space via content-addressable store
- First-class monorepo support with workspaces
- Requires separate installation
- Strict node_modules can break rare packages
- Some CI environments need extra setup

Which do you use?
Who Should Choose What?
Stick with npm if:
You are a beginner learning Node.js, work on a single small project, or your team has no interest in changing tools. npm gets the job done and requires zero setup.
Switch to pnpm if:
You work on multiple projects, use monorepos, care about disk space, or want faster CI builds. The switch takes 5 minutes and the speed difference is immediately noticeable.
Consider Yarn if:
You want Plug'n'Play (PnP) for zero node_modules, or your team is already using Yarn Berry. Yarn is a solid middle ground between npm and pnpm.
