What the data tells us

Key capabilities you'd miss

Choosing Firebase Authentication means going without Drag-and-drop builder, Database connections, API integrations (which Retool offers). Choosing Retool means losing Email/password, Google OAuth, Apple OAuth. These are the features that typically drive the final decision — check whether your workflow depends on any of them before committing.

What company size tells you

Retool (501-1,000 employees) has the engineering bench to ship features across many fronts but may iterate slower on individual requests. Firebase Authentication (100,000+ employees) typically ships faster on its core product but may lag on peripheral features. Consider which matters more for your roadmap.
