Hey Product Hunt! I'm Noman Hassan, and I built Porssisahkon.fi because I was frustrated watching Finnish users pay too much for electricity without real-time price visibility. The existing tools were outdated, slow, or too complex. So I built something better and completely free. What makes it different: → Quarter-hour (vartti) pricing that competitors don't show → 20+ Finnish city pages → EV + solar calculators built-in → Installable as PWA on mobile → Loads in under 1.5 seconds The results surprised me: 48 pages indexed by Google in just 17 hours of launch. Google even sent an official email confirming impressions started within 24 hours. Built solo with: Next.js 14 • TypeScript • Supabase • Cloudflare Pages • ENTSO-E API (free govt data) Total hosting cost: €0/month Would love your feedback, especially from anyone in Finland or the energy sector! What features would you want next?
