The training pipeline is also on Github! [1]

I was experimenting with running the wasm version of bergamot-translator (the translation engine used by the addon) in node [2].

However, if you want more performance, using the Python library [3] or the native C++ interface [4] gets you further because the wasm build is limited to a single thread and thus a blocking interface, and can't use all the processor specific optimisations that are in the native builds.

EDIT: Another option is using translateLocally [5], which is a Qt desktop app based on bergamot-translator. It has a native messaging API that is designed as a much faster alternative to the wasm build for browser extensions, but it can also be used from Python [6].
