## Side by side

| | PixelRAG | hindsight |
|---|---|---|
| Size | 59,214 lines written, 141 code files | 775,545 lines written, 1,263 code files |
| Who writes it | 24.1% of its commits signed by AI. With Claude Code | 6.8% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push November 11, 2026, 133 commits, 10,914 stars | Last push November 12, 2026, 4,120 commits, 60,699 stars |
| Tests | 45 test files. 16.3% of its code files have a test that imports them | 1,381 test files. 28.2% 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.
