About Allsupers
Allsupers is an independent UK grocery price comparison site, launched in 2026 by developer Pieter from Rotterdam, the Netherlands. The site compares daily prices across more than 130,000 products at 6 UK supermarkets — Tesco, Sainsbury's, ASDA, Morrisons, Waitrose and Aldi — converting every price into a unit price per kilogram, per litre or per piece so different pack sizes can be compared on equal footing. Allsupers is free for everyone, requires no account, and shows no advertising between the prices. For our savings methodology we use a 30-product reference basket weighted by Office for National Statistics (ONS) CPIH categories, which represent how UK households actually allocate spend across food, drink and household staples. According to the ONS, UK households spend on average £64 per week on food and non-alcoholic drinks; our basket shows roughly 10 to 16 percent savings by shopping at the cheapest two stores.
Our story
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 high accuracy. All prices are updated daily, including current promotions and offers.
