prometheus/prometheus has 453,215 source lines of code out of 543,787 total lines across 1,439 files, counted from the 3fab29b0da5f31f98893b73bcc2b20fcf79d0e1e ref at commit 3fab29b0da5f 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 prometheus/prometheus to commit 3fab29b0da5f, 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.
