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

ToolJet

  • Free and Pro tiers cap end users at 50, which may be too low for apps needing broad internal distribution.
  • Enterprise pricing starts at a steep $3,000/month, a large jump from the $199/month Team plan.
  • AI credits reset monthly and do not roll over, penalizing uneven month-to-month usage.
  • Smaller integration and community ecosystem than more established players like Retool.
