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

PostgreSQL

  • Gold-standard open-source SQL engine
  • Huge extension ecosystem (including vectors)
  • Foundation for many modern BaaS platforms
  • You assemble auth/storage yourself
  • Ops complexity grows without a managed host
  • Not a serverless product by itself

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
