Why the models rank Firebase — on best backend-as-a-service for startups

The most complete low-operations choice, especially for mobile: mature authentication, Firestore, functions, hosting, push notifications, analytics, crash reporting, offline synchronization, and proven Google Cloud scale

Why the models rank Supabase — on best backend-as-a-service for startups
