Where each one falls short

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

Firestore

  • The no-cost Spark plan caps Standard edition at 50,000 document reads, 20,000 writes and 20,000 deletes per day
  • The Spark plan caps storage at 1 GiB and network egress at 10 GiB per month
  • Charging is per document read, so a query returning many documents bills for every one of them
  • Going beyond the free thresholds requires the pay as you go Blaze plan billed at Google Cloud rates with no fixed monthly ceiling

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
