Where each one falls short

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

Appwrite

  • Smaller ecosystem compared to Firebase; fewer third-party integrations and extensions
  • Analytics, crash reporting, and A/B testing not included (Firebase includes these)
  • Requires infrastructure management for self-hosted deployments; not fully managed like Firebase Cloud
  • Mobile app support not as mature as Firebase's native iOS/Android SDKs

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
