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 App (which can work with your local instance after enabling dev mode)

What is Open Food Facts?

A food product database

Open Food Facts is a database of food products with ingredients, allergens, nutritional facts and all the tidbits of information that is available on various 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 and Windows Phone apps 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 (i.e available to everyone). 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!

Helping with HTML and CSS
