About Allsupers

Allsupers was built by Pieter, a developer from Rotterdam, the Netherlands. The idea started over a decade ago when he worked at a supermarket and wondered why the same jar of peanut butter costs more at one store than another.

What began as curiosity grew into a personal mission: showing consumers how much money they unknowingly miss out on. Allsupers compares daily prices across major UK supermarkets — from individual products to complete shopping lists.

The tool uses AI to match products across supermarkets with over 99% accuracy. All prices are updated daily, including current promotions and offers.
