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

Penpot

  • Smaller user base and community compared to Figma means fewer templates and resources
  • Self-hosting requires Linux server and Docker knowledge for technical setup
  • Real-time collaboration features may have performance issues with very large design files
