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

Parse Server

  • Deployment complexity and scaling challenges require operational expertise
  • Requires database management skills for MongoDB or PostgreSQL administration
  • Smaller community and ecosystem compared to Firebase or cloud alternatives
  • Query depth bypass vulnerability allowing denial-of-service attacks via complex REST/GraphQL queries
  • Stored XSS vulnerability through SVG file uploads requires patching
