Hey Product Hunt community! Most online calculator sites today are painful to use: buried under aggressive display ads, slow reload cycles, paywalls, or forced email signups just to calculate basic math or business numbers. I built Calcutrix to bring back clean, lightning-fast utility to the web. It is a directory of 2,000+ specialized calculators spanning finance, business, real estate, engineering, and daily logistics. Why it's different: • Instant Client-Side Execution: Built with Astro and React so computations happen locally in your browser with zero server latency. • Privacy-First: Your inputs never leave your device—zero telemetry or data harvesting. • Friction-Free: No signups, accounts, or paywalls. Open, compute, and get back to your work. • PWA Ready: Installable directly on desktop or mobile for fast offline access. I’d love to hear your feedback, feature ideas, or any custom calculators you'd like to see added next!
