Open Prices - the first open crowdsourced database of food prices
2025-06-18 , Main stage

Last year, Open Food Facts launched a new project to collect food prices, Want to track your consumption habits? Measure inflation? Or contribute to more transparency?
We’ll show how, starting from zero and without any web scraping, the community gathered 50k prices in just a few months. Each is geo-located (OpenStreetMap) and verified with a proof image (price tags or receipts).
We’ll also give a glimpse of what’s to come, with the development of in-house image detection models to extract, distribute and speed-up price contribution. And support the community in building reuses with the data!
