## Short Answer

OctoCounts is a free source lines of code (SLOC) counter for public GitHub repositories. Users paste a public GitHub URL, optionally choose a branch, tag, or commit SHA, and OctoCounts downloads the source archive, runs tokei, caches the result by commit and analysis options, and returns language-by-language counts. Users can also install the Chrome, Edge, or Firefox extension to see a SLOC card in the GitHub repository sidebar.

Browser extension stores: [Chrome Web Store](https://chromewebstore.google.com/detail/octocounts-%E2%80%94-github-sloc/gkgjpjdnaklagijmekoolhcpebmoldbj), [Microsoft Edge Add-ons](https://microsoftedge.microsoft.com/addons/detail/octocounts-%E2%80%93-github-sloc-/ehifednhpbpekkadndaipnngopbhpoim), and [Firefox Add-ons](https://addons.mozilla.org/en-US/firefox/addon/octocounts-github-sloc/).

## Primary Use Cases

- Count lines of code in a public GitHub repository.
- Compare repository size, code lines, comments, blanks, and language mix.
- Compare two repositories, forks, branches, tags, or commits.
- Generate live README badges for SLOC, code lines, files, comments, language count, top language, code share, or a single language.
- Export reports as text, JSON, or a 1200x630 PNG share card.
- Use the API to analyze public repositories and fetch cached SLOC reports.

## Report Pages

- Pattern: `https://octocounts.com/github/:owner/:repo`
- Branch/tag pattern: `https://octocounts.com/github/:owner/:repo/tree/:ref`
- Commit pattern: `https://octocounts.com/github/:owner/:repo/commit/:sha`
- Each cached report page includes a citable answer block, language table, JSON-LD, and an embedded machine-readable report summary.

## API Summary

Base API: https://api.octocounts.com

```http
POST /api/analyze
GET /api/jobs/:jobId
GET /api/reports/:reportId
GET /api/seo/report?provider=github&owner=:owner&repo=:repo
GET /api/seo/recent
GET /api/seo/popular
GET /api/seo/monoliths
GET /api/seo/sitemap
GET /og/github/:owner/:repo
GET /badge/:owner/:repo
GET /badge/:owner/:repo/branch/:branch
GET /badge/:owner/:repo/tag/:tag
GET /badge/:owner/:repo/commit/:sha
```

`repoUrl` must be a public `github.com` URL. Private repositories and source-code uploads are not supported.
