Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Eclipse IDE

  • Startup time and UI responsiveness lag behind newer editors like VS Code.
  • Plugin quality and compatibility can be inconsistent across versions.
  • Modern language support (e.g. for web frameworks) is weaker than dedicated tools.
  • Configuration and workspace setup has a steeper learning curve for newcomers.

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
