RosaeNLG is a Natural Language Generation library for node.js or client side (browser) execution, based on the Pug template engine. It was previously known as FreeNLG.
Fully supported languages (with grammar, gender etc.) are English, French, German, Italian and Spanish but you can generate texts in any other language with less features.
RosaeNLG is complete enough to write production grade real life NLG applications.
French demos are available.
You can run RosaeNLG in docker.
You can also play around with a client side editor, compiler and renderer with an in browser editor or directly here:
