Open Food Facts is a non-profit project made entirely by volunteers, we do need you.

No smartphone? No problem: you can also use your camera to add products directly on the web site.

You can help us complete products by selecting and cropping photos and filling in information.

Expert help needed

Developing Open Food Facts also requires specialized knowledge and expertise in many different areas:

  • Project management

    We have tons of ideas and you probably have even more, but it is quite a challenge to prioritize them, to build a roadmap, and to manage projects when every participant is a volunteer with often limited time available.

  • Design

    We need help to build a better user experience on the Open Food Facts web site and mobile app, to improve their design, to create impactful presentation materials etc.

  • Development

    We have a lot of development work to do. On the Open Food Facts backend (Perl and MongoDB), API (JSON), web site (templatized HTML5, JS, Foundation), iOS and Android apps (a Java/Kotlin version on Android, and a Swift version on iOS, both needing volunteers), a Flutter app for iOS and Android, but also to build new cool reuses etc. We have projects in many programming languages to ensure anyone can reuse and contribute to Open Food Facts, in any language. We also have a growing Artificial Intelligence effort to simplify contribution work. Our code is on GitHub.

  • Community building

    We need to build local communities in all countries and at the same time unite them globally.

    It is very difficult to bootstrap a local community in a country without living there, so your help to find the first very motivated participants is essential. Are you one of them?

  • Communication

    We are not sure what to write here, could you help?

    More seriously, there are lot of cool things that users, contributors and reusers do with Open Food Facts, it would be great to get more people to know about it. In particular, we need help for public and media relations.

  • Special projects

    There are lots of interesting and original applications of food open data that we could work on with government food agencies, food producers, researchers, universities, schools, NGOs etc. Maybe you already have ideas? If you do, please help us to push them forward.


Let's talk!

A lot of ideas, energy and enthusiasm are shared in our contributors community, join us!

Here are some places where you can meet other contributors, talk to them and work with them:

  • Slack

    Slack is the best way to interact and collaborate with other contributors, developers and reusers. It's a discussion forum you can access from your browser or your phone. It completely changed how we work together. Please try it, click on the button below to get invited to our Slack.

  • Facebook groups

    We have Facebook groups for Open Food Facts contributors in many languages. Joining them is a good way to get news about the project and to share announcements to a wider audience.

  • Wiki

    We also have a wiki that we use to collaboratively document Open Food Facts and its sub-projects. From the wiki, you can learn how to help translate the multilingual information (categories, labels etc.) a food product might have (using what we call taxonomies). You can even help add a food category or a label that is not yet supported by Open Food Facts.
