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

RapidAPI

  • RapidAPI Enterprise Hub minimum seat requirement is 5 seats per the embedded pricing page configuration (SEATS_MINIMUM: 5).
  • RapidAPI places a $0.50 USD temporary credit card authorization hold when subscribing, refunded only if no overage charges occur within 7 days.
