pnpm vs npm vs yarn in 2026: I ran all three on my real monorepo and it forced me to change my mind

Short summary

Benchmarks from a real Next.js monorepo show pnpm 53% faster on cold install and 50% smaller than npm. pnpm's strict dependency resolution breaks packages like Radix UI that assume npm's implicit hoisting—fixed via selective public-hoist patterns. npm v10 improved significantly; yarn's disk savings don't justify its compatibility cost. pnpm wins in 2026, but requires production configuration.

• •pnpm achieves 53% faster cold installs and 50% smaller disk footprint versus npm on real monorepo
• •Strict dependency hoisting breaks implicit dependencies (e.g., Radix UI); solved with selective public-hoist patterns in .npmrc
• •npm v10 closed the gap significantly; yarn Berry's PnP incompatibility makes it hardest to justify today
