## Side by side

| | LightRAG | OpenViking |
|---|---|---|
| Size | 442,998 lines written, 338 code files | 1,109,640 lines written, 1,964 code files |
| Who writes it | 19.8% of its commits signed by AI. With Claude Code, Codex, GitHub Copilot, Cursor, and Jules | 8.2% of its commits signed by AI. With Claude Code, Cursor, and Codex |
| Activity | Last push October 29, 2026, 8,260 commits, 40,452 stars | Last push October 31, 2026, 3,051 commits, 41,225 stars |
| Tests | 676 test files. 66% of its code files have a test that imports them | 1,353 test files. 56.6% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
