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
Moesif
- Free tier is aimed at hobbyists and small projects, limiting scale before paid usage-based pricing applies.
- Usage-based pricing on the Growth tier can make costs less predictable at high event volumes.
- Requires instrumenting APIs with SDKs, adding setup overhead compared to zero-config tools.
- Focused specifically on API analytics rather than full API gateway or design functionality.
