Firebase
Firebase — Choose it first for consumer mobile apps that need excellent offline behavior and real-time sync, accepting its document-oriented Firestore model and deeper Google-platform lock-in.
ChatGPT
Supabase
For a new app, my default choice is Supabase unless you have a clear reason to optimize for mobile offline sync, edge-native workloads, or a highly reactive TypeScript backend.
ChatGPT
Where the models split.
Across the 1 category Firebase and Supabase 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 Supabase ahead at least as often as not, with Gemini the most lopsided.
