👋 Hey Product Hunt!
I built Llenoporfavor because every time fuel prices surged in Spain, I'd spend 5 minutes scrolling through cluttered apps full of ads and signup walls just to save €5 at the pump.
The thing is , all the data is already public. The Spanish government requires every gas station to report prices daily via an open API. But none of the consumer apps used it well: they were either slow, full of ads, required registration, or all of the above.
So I made the tool I wanted to use:
🗺️ Open the map. That's it. No signup, no download, no tracking. Just a Leaflet map with every gas station in Spain color-coded by brand and price.
🎰 "I'm feeling lucky" mode: Picks the best station for you in 10 km based on a weighted score of price + distance. One tap.
💚 Low-cost filter: Spain has a booming low-cost gas station market (Plenoil, Petroprix, Ballenoil). You can filter to see only these — typically 10-15 cents/liter cheaper.
🔋 Fill-up calculator: Type your tank size, see exact cost per fuel type.
❤️ Favourites: Save the stations on your commute, filter to see only those.
📊 National price trends: Historic charts of average prices, so you know if today is a good day to fill up.
📱 Installable as a PWA: No App Store needed. Add to home screen and it behaves like a native app.
💰 How much can you save? With a 50-liter tank and a 15-cent difference between stations (very common in Spain), that's €7-8 per fill-up. Fill up weekly and you're looking at €400-500/year saved — without changing your habits.
Tech stack: Plain HTML/JS + Leaflet + the government's public API. Hosted on GitHub Pages. No backend, no database, fully static. The entire product fits in a single file.
This is not a startup ,just a free tool. No VC, no subscription, no paywall. If you're outside Spain: the concept works anywhere governments publish fuel data (most of Europe does).
Feedback welcome , especially if you're a Spanish driver. I'm here in the comments all day. 🙌
