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
