Building a language learning app meant I needed a backend that could handle realtime sync, multilingual support, and type-safe code. I didn’t start with Convex—I evaluated Firebase, PlanetScale, Supabase, Neon, and others first. Each had tradeoffs: Firebase felt disjointed and buggy; PlanetScale lacked international support; Supabase leaned too hard into SQL; and Neon made realtime too complicated. What made Convex different was how little backend glue I needed to write. Realtime sync just worked. TypeScript felt native. My frontend felt alive without hacks. It felt like hiring a backend team on day one. A year later, I’m still shipping fast—and glad I made the switch. This post breaks down what I found, what failed, and why Convex ended up being the best database for a modern TypeScript app like LanguageHopper.
