The short version

  • Each has a real cost: Firebase Realtime Database the no-cost Spark plan caps storage at 1 GB, downloads at 10 GB per month and simultaneous connections at 100; Airtable hitting a plan limit blocks adding records or attachments entirely until you upgrade, rather than degrading gracefully
  • They diverge on capability: Firebase Realtime Database covers Real-time Sync, Airtable covers Spreadsheet-database hybrid.

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

Airtable

  • Hitting a plan limit blocks adding records or attachments entirely until you upgrade, rather than degrading gracefully
  • Team is $20 per user per month and Business $45, both at the annual rate
  • Automation and API usage are capped by plan
  • Enterprise Scale pricing is not published
