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
Ninox
- Paid plans are priced per user starting around 25 euros per month, and offline desktop and mobile access is limited to the higher Business and Enterprise tiers
