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

Notepad++

  • Windows-only, with no official native macOS or Linux build.
  • Lacks built-in debugging or project/build management found in full IDEs.
  • Plugin quality and maintenance varies since they are community-contributed.
  • No built-in version control integration beyond what plugins provide.
