Bayen
Bayen is a free, open-source food product scanner built specifically for the Moroccan market. Users scan barcodes of products found in local supermarkets and get an instant health score out of 100, combining Nutri-Score (nutritional quality), NOVA classification (processing level), and an additive safety analysis. The app also suggests healthier alternatives in the same category, displays a full nutritional breakdown, and flags ingredients that exceed WHO thresholds. A citizen initiative by N0 and Netspace, it's community-driven — anyone can contribute products, correct data, and climb the contributor leaderboard.

The platform is a PWA installable on any phone, with bilingual support (French and Darija). The gamified contribution system awards points for adding products, uploading photos, and correcting data, with four contributor levels from Nouveau to Vérifié. Product data can also be bulk-imported from Open Food Facts (ODbL), making it easy to bootstrap the catalog while building a Morocco-specific database.
