Hi Product Hunt! I built ShrinkWatch EU because shrinkflation is hard to spot: a pack goes from 500 g to 450 g, the price stays the same, and the shelf tag looks unchanged.
Online shops in the EU must show a unit price, but it is often tiny, missing or wrong, and it never tells you the pack was bigger last month. ShrinkWatch EU adds a small badge with the price per kg, litre or piece, cross-checks the shop's own figure, and remembers pack sizes you have seen so it can warn you when one shrinks.
It is checked on real product pages at shops like Lidl, Kaufland, Rewe, dm, Carrefour, Monoprix, Albert Heijn, Mercadona, Conad, ICA and Willys. Everything stays in your browser: no account, no analytics, no network requests.
If your shop is missing or shows a wrong number, I would love a product link in the comments or on GitHub.
