Convex
Convex — My favorite for TypeScript teams building collaborative, reactive web apps, because its transactional functions and automatically subscribed queries eliminate a great deal of usual real-time and cache-invalidation work.
ChatGPT
Express
Node.js + Express — Best general-purpose custom backend if you want flexibility and can handle more of the architecture yourself.
Perplexity
Where the models split.
Across the 1 category Convex and Express both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks Convex ahead at least as often as not, with Perplexity the most lopsided.
