Hey everyone, Jose here. I got tired of opening five tabs just to convert a CSS unit or double-check a breakpoint, so I built WebDevCalc to keep those quick answers in one place. Everything is free, there's no login, and nothing is stored. The ones I reach for most are the CSS unit converter and the responsive breakpoint planner, plus there are short references on Core Web Vitals, structured data, and Open Graph tags. I'd genuinely love to hear which tool you'd want added next.
