GMB : Gasolinera Más Barata

GMB (Gasolinera Más Barata) is a Chrome extension designed to help users in Spain, France, Portugal, and Andorra quickly find the cheapest fuel prices nearby or in a searched city. Unlike map-based apps, GMB provides a straightforward list of gas stations sorted from cheapest to most expensive, with distances calculated based on actual mileage. It supports fuel types like Diesel A, SP95, SP98, LPG, and more, and includes helpful features such as real-time price updates with alerts for outdated data, route creation via your preferred navigation app, favorites for quick access, night mode, and an optional map view.

GMB also allows users to report incorrect prices to improve accuracy, although it relies on publicly available government data and does not take responsibility for price correctness. The extension requires location permissions to show nearby stations but can also run via city input without location. Ads partially finance the service but can be removed for free, enhancing user experience. This tool is ideal for budget-conscious drivers who want transparent, easy-to-access fuel pricing across several European countries.
