Hey Product Hunt! 👋

Hey Product Hunt!

I'm smail, 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 "k dem tazminat " (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.
