# pnpm vs Yarn: source lines of code compared

As of 2026-09-07, pnpm/pnpm contains 649,110 total lines (547,771 code) across 3,501 files, while yarnpkg/berry contains 137,547 total lines (104,439 code) across 1,243 files as of 2026-07-30. pnpm/pnpm is about 5.2x the size of yarnpkg/berry by code lines. Code size is not code quality: a larger count only means more source material, not a better or worse project.

## Compare FAQ

### Which has more lines of code, pnpm/pnpm or yarnpkg/berry?

pnpm/pnpm has more code: 547,771 code lines versus 104,439 for yarnpkg/berry, about 5.2x as much, based on cached OctoCounts reports as of 2026-09-07.

### Does more source lines of code mean more complexity?

Not necessarily. SLOC measures size, not complexity, quality, or maintainability. A larger codebase can mean more features, more generated or vendored code, more verbose language idioms, or more tests — none of which imply the code is harder to work with. Use SLOC to gauge the scale of what you'd be reading or maintaining, not as a quality signal for pnpm/pnpm, yarnpkg/berry, or any repository.

### How is this comparison calculated?
