Hi Product Hunt! 👋 I'm Julien Dubuc, an engineering student and developer. Like many people, I had a bunch of $10 or $15/month subscriptions. They felt completely harmless until I sat down and calculated their cost over a 5-year period. Realizing that a couple of unused streaming and gym services could have paid for a trip to Japan was a real wake-up call. 🤯 So, I built Subscription Shock this weekend. It's a simple, fast web utility that takes your monthly subscriptions and calculates their 1-year and 5-year financial impact. But instead of just giving you a number, it gives you a "shock" equivalent (e.g., a next-gen console, a MacBook Pro, a car down payment) to help trigger better financial decisions. ⚙️ The Tech Stack: 100% Vanilla JavaScript (No heavy frameworks) TailwindCSS for the HUD/Cyberpunk UI Runs entirely locally using LocalStorage (zero data leaves your browser) Dynamic bilingual and currency formatting (€/$) using the native Intl API. I also integrated it directly into my interactive Cyberpunk developer portfolio as a 'deployed module' (you can check the footer link to see it!). I built this to practice my front-end skills and help people manage their budget. I'd love to hear your feedback on the UI/UX, the code, and what your 5-year "shock" score was! Thanks for checking it out! ❤️
