What it is

Google's backend suite: Firestore and Realtime Database, Authentication, Hosting, Cloud Functions and Cloud Messaging. The no-cost Spark plan gives 1GiB Firestore storage with 50,000 reads and 20,000 writes per day. Blaze is pay-as-you-go and is required for Cloud Functions and outbound networking.

Why it earns a slot

Fifteen years of tutorials means models generate Firebase code confidently. An official MCP server ships inside firebase-tools, and Firebase Studio is Google's own AI app builder wired straight into it.

Know before you commit

Per-document read billing punishes chatty UIs, and a runaway loop on Blaze can produce a shocking bill overnight. NoSQL modelling also resists later migration to SQL.
