# Svelte vs React: source lines of code compared

As of 2026-09-12, sveltejs/svelte contains 100,475 total lines (58,801 code) across 506 files, while facebook/react contains 460,163 total lines (364,527 code) across 2,133 files as of 2026-09-12. facebook/react is about 6.2x the size of sveltejs/svelte 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. sveltejs/svelte was counted at ref main (commit 6eb720a1b7ca) on 2026-09-12; facebook/react was counted at ref main (commit 019019be403c) on 2026-09-12.

## Compare FAQ

### Which has more lines of code, sveltejs/svelte or facebook/react?

facebook/react has more code: 364,527 code lines versus 58,801 for sveltejs/svelte, about 6.2x as much, based on cached OctoCounts reports as of 2026-09-12.

### 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 sveltejs/svelte, facebook/react, or any repository.

### How is this comparison calculated?

Methodology: both counts come from cached OctoCounts reports generated with tokei. sveltejs/svelte was counted at ref main (commit 6eb720a1b7ca) on 2026-09-12; facebook/react was counted at ref main (commit 019019be403c) on 2026-09-12. See the counting methodology for ignored directories and analysis options.

### Can I compare a different branch, tag, or commit?

Yes. This page shows the default branch for each repository. Use the interactive comparison tool to pick any public GitHub repository, branch, tag, or commit SHA for both sides and get a fresh side-by-side report.
