## Side by side

| | mem0 | payload |
|---|---|---|
| Size | 234,363 lines written, 636 code files | 1,054,090 lines written, 4,857 code files |
| Who writes it | 3.6% of its commits signed by AI. With Claude Code and Cursor | 0.6% of its commits signed by AI. With GitHub Copilot, Claude Code, and Cursor |
| Activity | Last push October 29, 2026, 2,650 commits, 68,064 stars | Last push October 30, 2026, 14,760 commits, 45,594 stars |
| Tests | 324 test files. 46.2% of its code files have a test that imports them | 2,448 test files. 12.6% 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.
