Engine by engine
Supabase vs Firebase: what the data says
When buyers ask AI assistants like ChatGPT, Claude and Gemini to recommend backend as a service, Firebase is recommended more often than Supabase — scoring 98/100 for AI visibility versus 37/100. Firebase shows up in 100% of AI answers to real buyer questions; Supabase shows up in 50%.
The gap is widest on Gemini, where Firebase is clearly favoured: Supabase is recommended 40% of the time and Firebase 100%. Because each engine draws on different sources, a brand can lead on one and trail on another — which is why it pays to track all three rather than assume one result holds everywhere.
In practice, an AI assistant asked “What are the best backend as a service options for building a web application?” is far likely to put Firebase on its shortlist. Supabase is largely invisible in AI answers for backend as a service — and since these shortlists are increasingly where buying decisions start, that's a gap worth closing.
