CalcRegistry

A fast, clean library of 230+ calculators and tools.

CalcRegistry is a massive, high-performance directory of over 230+ utility tools across Finance, Photography, Health, Construction, and more. As a developer with 26 years of experience, I built this to replace the slow, ad-cluttered sites of the past. Using Astro and Vue 3, every tool loads instantly. Whether you’re calculating complex prime factorizations, engineering units, or photography exposures, the focus is on clean UI and "showing the work" so you understand the logic.
