Where each one falls short

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

KeystoneJS

  • Database support is limited to PostgreSQL, MySQL and SQLite
  • Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
  • Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
  • Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

Kubernetes

  • Complex initial setup and configuration with multiple interdependent components
  • Significant resource requirements for both hardware infrastructure and specialized human expertise
  • Expensive specialized talent in Kubernetes domain; hiring costs prohibitive for many organizations
  • New security challenges around container isolation and network security requiring robust measures
  • Requires continuous maintenance and updates to stay current with releases and security patches
