## Side by side

| | hello-agents | mem0 |
|---|---|---|
| Size | 226,666 lines written, 1,268 code files | 234,363 lines written, 636 code files |
| Who writes it | 2.4% of its commits signed by AI. With Codex, Cursor, and Claude Code | 3.6% of its commits signed by AI. With Claude Code and Cursor |
| Activity | Last push October 13, 2026, 660 commits, 84,924 stars | Last push October 26, 2026, 2,650 commits, 67,923 stars |
| Tests | 97 test files. 6.6% of its code files have a test that imports them | 324 test files. 46.2% 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.
