# pandas vs llama_index

pandas and llama_index share 15 technologies: gcsfs, psycopg2-binary, pyiceberg, pymysql, pyarrow, s3fs, ipywidgets, matplotlib, SQLAlchemy, nbformat, lxml, jinja2, beautifulsoup4, nbconvert, and xlrd. Both are written in Python.

- [pandas-dev/pandas](https://seerepo.com/r/pandas-dev/pandas): Flexible and powerful data analysis / manipulation library for Python, providing labeled data structures similar to R data.frame objects, statistical functions, and much more
- [run-llama/llama_index](https://seerepo.com/r/run-llama/llama_index): LlamaIndex is the document processing platform for AI

| Size | 758,101 lines written, 297 code files | 473,236 lines written, 2,055 code files |
| Who writes it | 4.2% of its commits signed by AI. With Claude Code, GitHub Copilot, and Devin | 0.2% of its commits signed by AI. With Claude Code, Cursor, and GitHub Copilot |
| Activity | Last push November 5, 2026, 36,566 commits, 50,368 stars | Last push November 5, 2026, 7,963 commits, 52,820 stars |
| Tests | 1,263 test files. 56.6% of its code files have a test that imports them | 1,607 test files. 46.5% 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.
