- Only in hindsight: Postgres, Claude

## Side by side

| | DeepTutor | hindsight |
|---|---|---|
| Size | 818,773 lines written, 2,153 code files | 746,685 lines written, 1,184 code files |
| Who writes it | 24.2% of its commits signed by AI. With Codex, Claude Code, Cursor, GitHub Copilot, and CodeRabbit | 6.9% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push October 28, 2026, 2,305 commits, 47,672 stars | Last push October 28, 2026, 3,952 commits, 54,541 stars |
| Tests | 1,366 test files. 21.7% of its code files have a test that imports them | 1,315 test files. 30.7% 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.
