Build machine learning applications with Delta, an open-source framework implemented in Rust.
Catniff
Catniff provides JavaScript developers with a Torch-like deep learning framework.

About Catniff
Catniff is a small Torch-like deep learning framework for JavaScript, originally inspired by Tinygrad APIs. This project is under development. It installs through npm, with Node v24 recommended for float16 support and fallback to float32 otherwise. It suits JavaScript developers building or studying neural networks directly in JavaScript.
