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.

PayPal

  • Currency conversion on international purchases and sends carries a 4.00 percent fee, and 3.00 percent in other conversion scenarios
  • Instant transfer to a bank or debit card costs 1.75 percent of the amount, with a minimum of 0.25 USD and a maximum of 25.00 USD
  • International personal transactions carry a 5.00 percent fee regardless of payment method, with a minimum of 0.99 USD and a maximum of 4.99 USD
  • Sending domestic personal payments funded by a credit card costs 2.90 percent plus a fixed fee of 0.49 USD
  • Instant transfers are capped at 25,000.00 USD per transaction
