Where each one falls short

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

QuestDB

  • Open-source edition lacks high-availability, distributed architecture, and enterprise security features
  • Enterprise edition pricing not published; requires contacting sales for custom quote
  • Ingestion limit of 20M rows/sec platform-dependent; may not scale to extreme throughput requirements

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
