Where each one falls short

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

Microsoft Azure API Management

  • Prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales
  • Two parallel generations of tiers, classic and v2, so the choice is which lineage before which size
  • The Developer tier is explicitly not for production
  • Self-hosted gateways and workspace gateways are charged separately from the service

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
