Firebase
Firebase is a Backend-as-a-Service (BaaS) platform launched by James Tamplin and Andrew Lee in April 2012. Acquired by Google in October 2014, it is now the largest and most mature mobile and web full-stack development platform globally. Firebase is Google's complete app backend suite, centered on Firestore/Realtime Database, with authentication and storage.

Pros & cons
Firebase
- Dual NoSQL databases: Firestore + Realtime Database
- Mature mobile/web BaaS ecosystem
- Realtime + auth + storage out of the box
- Deep Google Cloud integrations
- NoSQL model — not SQL/Postgres
- Vendor lock-in concerns
- Query flexibility can frustrate SQL-first teams
Redis
- Extremely fast in-memory performance
- Versatile data structures for caching and queues
- Wide client and cloud hosting ecosystem
- Not a primary relational system of record
- Memory cost and persistence trade-offs
- Licensing / product naming has evolved
