# mongodb/mongo SLOC report

> mongodb/mongo: 7,575,175 code lines at commit 37eae97fd90a, counted with tokei-14.0.0 on 2026-10-21. Saved result e4a72c66f766bc2151ebaca8f66bdcd8a270ec6c7cd43014b2f56521ebe414d4.

mongodb/mongo has 7,575,175 source lines of code out of 10,514,373 total lines across 39,273 files, counted from the master ref at commit 37eae97fd90a by the OctoCounts tokei engine on 2026-10-21. 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 37eae97fd90a, 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.
