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

PyCharm

  • PyCharm Pro commercial licence is USD 299/year (USD 29.90/month); personal licence is USD 109/year dropping to USD 68.25 by year three with loyalty discounts, per jetbrains.com/store inline pricing JSON checked 19 Aug 2026
