Where each one falls short

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

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.

Rocket Money

  • Successful bill negotiation costs a one time fee of 35% to 60% of the first year's savings
  • Premium is priced on a sliding scale and the help centre publishes no fixed monthly or annual amount, stating rates vary across platforms
  • Custom budget categories, financial goal plans, credit score tracking and real time account syncing are Premium only
  • The Premium free trial is 7 days
