C++

• EPI (license LGPL)
• eixx (license Apache2)

• erlualib (license MIT)

Python

• erlang_py (license BSD)
• py_interface Website, Github (license GPL)

Rust

• Rustler (license Apache, MIT)
• erlang-rust-nif

Ports and Network

For the situations when you still need the speed and can tolerate some call latency over, but don’t want to risk crashing your node: choose interaction over network or a port.
