What is Product Opener?

Product Opener is the server software for Open Food Facts and Open Beauty Facts. It is released under the AGPL license and is being developed in Perl, HTML and JavaScript as Free and Open-Source Software.

It works together with Robotoff, Open Food Facts' AI system (in Python, which can also be installed locally) and the Open Food Facts apps (which can work with your local instance after enabling dev mode)

What is Open Food Facts?

A food products database

Open Food Facts is a database of food products with ingredients, allergens, nutrition facts and all the tidbits of information we can find on product labels.

Made by everyone

Open Food Facts is a non-profit association of volunteers. 25.000+ contributors like you have added 1.7 million + products from 150 countries using our Android, iPhone or Windows Phone app or their camera to scan barcodes and upload pictures of products and their labels.

For everyone

Data about food is of public interest and has to be open. The complete database is published as open data and can be reused by anyone and for any use. Check-out the cool reuses or make your own!
