The Verdict
Firebase is built for mobile developers and startups, with a focus on firestore and authentication. Retool targets engineering teams and operations and leads with drag-drop-ui and database-connectors.
On pricing, Firebase is the clear winner for budget-conscious users — starting at $0/mo compared to $10/mo for Retool. That $10/mo difference adds up quickly for growing teams.
