This page compares the source lines of code (SLOC) of sveltejs/svelte and facebook/react 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 2026-09-06, sveltejs/svelte contains 100,451 total lines (58,803 code) across 509 files, while facebook/react contains 332,301 total lines (254,981 code) across 1,911 files as of 2026-09-06. facebook/react is about 4.3x 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.

Top languages in sveltejs/svelte: JavaScript (78.0% of code), TypeScript (14.1% of code), YAML (6.1% of code). Top languages in facebook/react: JavaScript (77.0% of code), TypeScript (19.5% of code), JSON (1.3% of code). JavaScript, TypeScript, JSON appear in both top language lists; YAML, HTML appear only in sveltejs/svelte's top languages; CSS, TSX appear only in facebook/react's top languages.
Methodology: both counts come from cached OctoCounts reports generated with tokei. sveltejs/svelte was counted at ref main (commit 5895c637b04d) on 2026-09-06; facebook/react was counted at ref 6c7b1a1d9898025bb087a3b97d875091e4f67cf3 (commit 6c7b1a1d9898) on 2026-09-06. 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.
facebook/react has more code: 254,981 code lines versus 58,803 for sveltejs/svelte, about 4.3x as much, based on cached OctoCounts reports as of 2026-09-06.
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.
