This page compares the source lines of code (SLOC) of expressjs/express and koajs/koa using cached OctoCounts reports. Code size is not code quality: a larger count only means more source material, not a better or worse project.
As of 2026-09-10, expressjs/express contains 9,400 total lines (2,617 code) across 70 files, while koajs/koa contains 8,539 total lines (6,418 code) across 14 files as of 2026-08-26. koajs/koa is about 2.5x the size of expressjs/express by code lines. Code size is not code quality: a larger count only means more source material, not a better or worse project.

Methodology: both counts come from cached OctoCounts reports generated with tokei. expressjs/express was counted at ref master (commit bed501c695a6) on 2026-09-10; koajs/koa was counted at ref master (commit 4a191b1fb7bc) on 2026-08-26. See the counting methodology for ignored directories and analysis options.
Evidence and next steps:
Note: code size is not code quality. OctoCounts only reports reproducible line counts and makes no claim that either project is better.
koajs/koa has more code: 6,418 code lines versus 2,617 for expressjs/express, about 2.5x as much, based on cached OctoCounts reports as of 2026-09-10.
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 expressjs/express, koajs/koa, or any repository.
