GPT

GPT-5 Mini

Prefers Firebase39 vs 61

“Firebase projects stronger trust and authority overall because it is backed by Google, surfaces well-known enterprise customers, extensive integrations, and a long, visible track record; these are strong third‑party validation signals. Supabase shows excellent developer‑focused social proof, case studies, and modern product presentation, but it lacks the same corporate backing and scale signals that make Firebase feel more authoritative to a general audience.”

GEM

Prefers Supabase57 vs 43

“Firebase (Company B) projects significantly stronger trust and authority due to its association with Google, clear presentation of numerous recognizable client logos (e.g., The New York Times, Duolingo, Venmo), and comprehensive product suite. Supabase also shows good social proof, but Firebase's backing by Google is a major differentiator in terms of established credibility and perceived stability.”
