Scan a barcode. See the score.
Point your phone or laptop camera at a grocery barcode. You get one Guava Score for nutrition, sustainability, and price, and each number names its source. Nothing to install.
The barcode is sent to Open Food Facts and Open Prices so we can read the public record. Guava does not save scans. A short history stays in this browser, and you can clear it. Green-Score is experimental outside France.
Look up a product
EAN-13, UPC-A, UPC-E, and EAN-8. The camera stays off until you ask.
Allow the camera, upload a photo, or type a barcode.
Point the camera at the barcode on the package. Nothing is recorded.
The score shows up here
Nutrition and sustainability come from Open Food Facts. Price comes from Open Prices. If a source has no score, this page says so.
