elastic/elasticsearch has 3,091,605 source lines of code out of 4,300,837 total lines across 21,945 files, counted from the main ref at commit 657b990d6944 by the OctoCounts tokei engine on 2026-09-10. 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 elastic/elasticsearch to commit 657b990d6944, 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.
