About Calcs
For Devs

Built for developers, by a developer.

Built for Developers

Calcs for Devs is a growing collection of free calculators and utilities built to make front-end work faster, easier, and less frustrating. The goal is simple: create clean, useful tools for CSS, layout, typography, color, and everyday development tasks without the clutter or distractions.

Why we built Calcs for Devs

We built Calcs for Devs because we kept running into the same problem: too many developer calculators felt clunky, outdated, or harder to use than they should be.

A lot of the small conversion and reference tools developers need every day are still scattered across different sites, inconsistent in quality, or missing the features that would actually make them genuinely useful.

So we built a cleaner, simpler set of calculators specifically for developers, the kind of tools we wanted to have in one place.
