Firebase vs Supabase: facts from official sources
A side-by-side of Firebase and Supabase for the database, built from facts on each vendor's own pages. They have too few model picks in October 2026 to compare yet.
Facts checked 2026-10-19Picks measured 2026-10-19Method
Model pick, not a product recommendation. The models answered without a repository, existing code or tools, so the index shows what a model names when nothing in the project constrains it. It says nothing about quality, security, price or market share.

What models picked
Not enough picks yet
What we do not measure
We do not measure price, quality, security, reliability, GDPR compliance or support. A model pick says what the models named, not which product is better for your project. For those questions use the vendors' own documentation: Firebase docs, Supabase docs.
