mongodb/mongo
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.
As of 2026-10-21 (commit 37eae97fd90a), mongodb/mongo contains 10,514,373 total lines: 7,575,175 code, 1,678,127 comments, 1,261,071 blank, across 39,273 files in 59 languages (top: C++ 33.9%). Custom configuration (tests excluded, docs excluded, generated excluded). Counted with tokei via OctoCounts.
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.
