# mongodb/mongo SLOC report

> As of 2026-08-31 (commit 248ca0ef42c2), mongodb/mongo contains 10,417,497 total lines: 7,507,958 code, 1,659,139 comments, 1,250,400 blank, across 38,931 files in 59 languages (top: C++ 33.8%). Counted with tokei via OctoCounts.

OctoCounts produced this report by resolving mongodb/mongo to commit 248ca0ef42c2, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
