I was working on a mobile app and struggled to properly visualize how it would look in real mobile viewports during development. Most existing tools were either desktop-focused or didn’t give a true mobile-first testing experience. That’s what inspired me to build Codrite — a simple online tool that lets developers preview and test their app code in both mobile and desktop viewports instantly. While building it, I focused on keeping the workflow lightweight and fast, so developers can quickly catch responsive issues without switching between multiple tools. My goal with Codrite is to make mobile-first testing easier, faster, and more accessible for every frontend developer. I’m also actively working on adding AI-powered features and additional tools to further improve debugging and testing workflows in future updates.
