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

Kustomer

  • Pricing not published; requires customised sales assessment and quote for exact costs
  • Voice (call), SMS, and WhatsApp support operate on separate pay-as-you-go pricing models
  • Customisation-based pricing structure means no transparent cost comparison with competitors
