OctoCounts Launch Kit
OctoCounts is a GitHub SLOC counter and browser extension. It shows actual files, lines, code, comments, blanks, and language totals for public repositories without cloning.

GitHub shows language percentages. OctoCounts shows actual source line counts: files, code, comments, blanks, and per-language totals. Use the web app, browser extension, README badge, GitHub Action, CLI, or MCP server.Launch Post
I built OctoCounts because GitHub's language bar is useful but incomplete.
It answers the practical question: how big is this repo, really?
- Browser extension: SLOC directly in GitHub's repo sidebar
- Web app: permanent public reports
- README badges: live SLOC badges that link to reports
- GitHub Action: PR comments for SLOC changes
- CLI and MCP: developer/agent workflows

Tagline (≤10 words)Free GitHub SLOC counter — real line counts, not percentages.
Short description (~60 words)OctoCounts is a free source lines of code (SLOC) counter for public GitHub repositories. It downloads the source archive for a pinned commit, counts it with tokei, and reports files, total lines, code, comments, blanks, and per-language totals — no cloning required. Available as a web app, browser extension, README badge, GitHub Action, CLI, and MCP server.
Long description (~300 words)OctoCounts is a free source lines of code (SLOC) counter for public GitHub repositories. GitHub's repository sidebar shows a language bar — a percentage breakdown by bytes — but never shows the numbers most developers actually want: how many files, how many total lines, how much of that is real code versus comments and blank space, broken down per language.
OctoCounts fills that gap. Paste a public GitHub URL, optionally pin a branch, tag, or commit, and it downloads the repository's source archive (never a full git clone with history), counts every file with tokei — a fast, Rust-based line counter — and returns a sortable, shareable report: files, total lines, code lines, comment lines, blank lines, and per-language totals, all pinned to an exact commit so the numbers are reproducible.
Reports are cached by commit SHA and tokei version, so re-analyzing the same commit is instant. Every report gets a permanent, shareable URL, can be exported as plain text, JSON, or a PNG card, and can be embedded as a live README badge that always reflects the current default branch, or pinned to a tag or commit for numbers that never change.
Beyond the web app, OctoCounts ships as a browser extension for Chrome, Edge, and Firefox that adds the same SLOC breakdown directly to GitHub's repository sidebar, a GitHub Action that comments SLOC changes on pull requests, a CLI (
OctoCounts only analyzes public repositories — no account, no GitHub token, and no source-code upload required. It's free with no premium tier, and the entire stack (Rust/Axum backend, React/TypeScript frontend) is open source under the MIT license.

Maker story (Product Hunt first comment / "why I built this")I kept wanting to know how big a repository actually was before depending on it, forking it, or spending an afternoon reading it — and GitHub's language bar never answered that; it shows percentages, not files or lines. Cloning a repo just to run tokei locally worked, but I was doing it often enough, especially for repos with a long git history, that it got old. So I built OctoCounts to skip the clone: paste a GitHub URL, get the real numbers.
