mongodb/mongo has 5,888,453 source lines of code out of 8,405,704 total lines across 29,659 files, counted from the 0a68308f0d39a928ed551f285ba72ca560c38576 ref at commit 0a68308f0d39 by the OctoCounts tokei engine on 2026-09-16. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving mongodb/mongo to commit 0a68308f0d39, 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.
