Where each one falls short

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

Betterment

  • Digital automated investing charges $5 per month fee for accounts under $24,000 balance
  • Premium advisory service requires minimum balance of $100,000 in eligible investments
  • Foreign transaction fees apply to checking account (though reimbursed after the fact)
  • High-balance fee discounts only available above $1,000,000 account balance

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.
