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

Xlinesoft

  • The purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade
  • Multiple database connections, REST API connections and single sign-on through Active Directory, Okta or SAML are Enterprise-only, which raises the price from $599 to $999 per developer
  • Self-hosted only. Hosting, database administration, backups, runtime updates and access-control configuration remain the customer's job, as Xlinesoft's own product facts page states
  • Applications built on Microsoft Access require a Windows web server
  • PHPRunner and ASPRunner.NET are separate products with separate licences, so moving a project between PHP and .NET is not covered by one purchase
