Hey Product Hunt! 👋
Hey Product Hunt! 👋
I'm İsmail, a solo developer from Istanbul. I built Hepsi Hesapla because Turkey desperately needed a modern, fast, and truly free calculation platform.
The problem: Every existing Turkish calculator site is bloated with ads, slow to load, and stuck in 2015 design. People searching "KDV hesaplama" (VAT calculator) or "kıdem tazminatı" (severance pay) deserve better.
The solution: 200+ tools, neo-brutalist design, JetBrains Mono font, sub-second load times, zero ads, zero registration. Every tool is updated with 2026 data.
Some numbers:
- 193 individual calculation tools
- 19 categories
- 6 blog posts with detailed guides
- Mobile-first responsive design
- 100/100 PageSpeed score target
I'd love your feedback! What calculators would you add? 🙏
