Where each one falls short

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

CrewAI

  • The free Basic tier caps at 50 workflow executions per month, with all higher usage requiring a custom Enterprise contract, as of August 2026.

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
