Worth it

Should I use pnpm?

Fast, disk space efficient package manager - pnpm.io

· 1 month ago

Adopt it if you write JavaScript — it is free, installs 2–3× faster than npm, and cuts disk use 50–70%. Skip it only if you have standardized on Bun or cannot afford lockfile and CI migration.

Confidence

High. Based on 15+ public sources. No named corporate users found in evidence; security findings are publicly disclosed CVEs.

Best for

  • JavaScript/Node teams with heavy dependency trees
  • Monorepo workspaces
  • CI pipelines where install speed matters
  • Disk-constrained developer machines

Not for

  • Non-JavaScript projects — it only manages Node packages
  • Teams all-in on Bun, which is 18× faster
  • Anyone expecting vendor support or SLAs — it is community OSS
  • Teams that cannot change lockfiles and CI config

Speed advantage shrinks vs Bun; benchmark against your own CI first

Guess: migrating npm/Yarn projects means lockfile conversion and CI rewiring
