# tfjs vs ivy

tfjs and ivy share 6 technologies: h5py, jaxlib, ml-dtypes, TensorFlow, flax, and jax. tfjs is written in TypeScript and ivy in Python.

- [tensorflow/tfjs](https://seerepo.com/r/tensorflow/tfjs): A WebGL accelerated JavaScript library for training and deploying ML models.
- [unifyai/ivy](https://seerepo.com/r/unifyai/ivy): Convert Machine Learning Code Between Frameworks

## What they share and what sets them apart

- In common: h5py, jaxlib, ml-dtypes, TensorFlow, flax, jax
- Only in tfjs: tensorboard-data-server, werkzeug, React, @react-native-async-storage/async-storage, react-native, Preact, prompt-toolkit, Rich, Keras, opt-einsum, optax, orbax-checkpoint, tensorflow-io-gcs-filesystem, tf-keras, tensorflow-hub, markdown, markupsafe, progress, expo-gl, expo-camera, jpeg-js, glamor, vega-embed, d3-selection, vega-lite
- Only in ivy: cryptography, PaddlePaddle, scikit-learn, torch, einops, torchvision, xgboost, psutil

## Side by side

| | tfjs | ivy |
|---|---|---|
| Size | 383,524 lines written, 2,527 code files | 482,091 lines written, 876 code files |
| Who writes it | 0% of its commits signed by AI | 0% of its commits signed by AI |
| Activity | Last push June 23, 2026, 6,042 commits, 19,155 stars | Last push October 22, 2026, 18,065 commits, 14,166 stars |
| Tests | 72 test files. 1.9% of its code files have a test that imports them | 444 test files. 12.1% 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.
