# plotly.py vs ray

plotly.py and ray share 7 technologies: pyarrow, Plotly, scikit-learn, scikit-image, jinja2, nbconvert, and psutil. Both are written in Python.

- [plotly/plotly.py](https://seerepo.com/r/plotly/plotly.py): The interactive graphing library for Python :sparkles:
- [ray-project/ray](https://seerepo.com/r/ray-project/ray): Ray is an AI compute engine. Ray consists of a core distributed runtime and a set of AI Libraries for accelerating ML workloads.

## What they share and what sets them apart

- In common: pyarrow, Plotly, scikit-learn, scikit-image, jinja2, nbconvert, psutil
- Only in plotly.py: umap-learn, jupytext, recommonmark, @lumino/widgets

| Activity | Last push November 3, 2026, 7,140 commits, 18,878 stars | Last push November 6, 2026, 32,373 commits, 44,213 stars |
| Tests | 155 test files. 1.2% of its code files have a test that imports them | 2,168 test files. 9.7% 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.
