FAQ
Vercel is generally stronger for Next.js frontend deployment. Firebase Hosting is attractive when the site belongs to an application already using Firebase backend products.
Not by itself for Firestore, Auth and Storage. You need separate backend products or integrations.
Yes. Host the frontend on Vercel and use Firebase client or server SDKs for backend services, with carefully configured credentials and security rules.
