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
Kong Gateway
- The free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.
- Plus tier caps API requests at 1M/month before incurring per-million overage charges.
- Enterprise pricing is custom and not published, making budgeting harder without sales contact.
- Configuration and plugin management can require significant operational expertise to run at scale.
