About

Boulingua is a free, openly licensed multilingual teaching platform created by S. Le Boulanger. It is built for language teachers and learners working in the German school system — specifically Gesamtschule — and for international learners of German following the Common European Framework of Reference (CEFR).

The platform brings together teaching units for three languages — English, French, and German as a foreign language — alongside a curated hub of free, openly licensed teaching resources. EFL and FLE units are organised by school year (Klasse) and curriculum-aligned, including Niveau-Differenzierung (G / M / E). The DaF units follow standard examination formats and are organised by CEFR level (A1 to C1).

All four sister sites share an identical design system, so a teacher or student moving between languages encounters the same navigation, the same typography, and the same visual rhythm. Consistency is a feature, not an accident.

Everything is dual-licensed: the website code under the MIT License, and the written content under Creative Commons Attribution-ShareAlike 4.0. Anyone can use, share, and adapt the materials with attribution.

All five sites are built with Hugo and share one platform — the same layouts, design tokens and quality gates arrive from a single kit repository. All five repositories are hosted under the boulingua GitHub organization and deployed via GitHub Pages.
