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

Firefly III

  • There is no official managed hosting, so a non-technical user has no easy on-ramp the way Actual Budget offers with its paid hosted sync.
  • The double-entry-influenced model is less intuitive for newcomers than simple envelope budgeting, and the learning curve is real.
  • Automatic bank sync depends on the community-run importer and third-party connectors, and coverage and reliability vary a lot by bank and country.
  • Mobile access is via a web interface rather than a polished native app, which is a step behind Actual Budget or Lunch Money on phones.
  • Because there is no company behind it, security patching and feature development depend entirely on volunteer maintainer time.
