What the data tells us

Key capabilities you'd miss

Choosing Firebase Authentication means going without Git push deploys, Preview deployments, Edge Functions (which Vercel offers). Choosing Vercel 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

Vercel (501-1,000 employees) has the engineering bench to ship features across many fronts but may iterate slower on individual requests.
