Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Firebase Realtime Database

  • The no-cost Spark plan caps storage at 1 GB, downloads at 10 GB per month and simultaneous connections at 100
  • The Spark plan does not support multiple databases in a project
  • Even on the paid Blaze plan simultaneous connections are capped at 200,000 per database
  • Billing is by data transferred out at $1 per GB plus $5 per GB stored, so chatty clients cost more than the data volume suggests

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based
  • Free tier trial of Pro features requires a credit card and reverts after 7 days
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead
