Thrift

Find the real bargain — compare price per unit on the shelf.

Thrift settles the "is the big pack actually cheaper?" question by comparing any products on price per unit — enter each price and size in grams, litres or count and it instantly ranks them and crowns the best value, showing how much you save. Built end-to-end with AI, it runs entirely in your browser with no login and no network, and the whole single-file source is downloadable to self-host or remix.
