FuelFinder is a weekend side project that pulls live UK fuel prices from the official open data feed and plots the cheapest unleaded, diesel and premium near you on a map, refreshed every 30 minutes. Free to use, no account needed, with optional email alerts when a station hits your target price.

Built deliberately without a framework or backend to speak of — just geolocation, the public price feed, and enough vanilla JS to make it feel usable. Source is on GitHub.
