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.

Vanguard

  • A 25 USD annual account service fee applies unless the account uses e-delivery, is a Cash Plus Account, is enrolled in an advisory service, or holds 1 million USD or more in qualifying assets
  • Broker assisted trades cost 25 USD each, waived only at 1 million USD in qualifying assets or with an advisory service
  • Options trades carry a 1 USD per contract fee on top of zero commission
  • Transaction fee mutual funds cost 20 USD per online trade below 1 million USD in qualifying assets, falling to 8 USD only at higher tiers
  • Outgoing wire transfers cost 10 USD unless the account is a retirement account or holds 1 million USD or more
  • Commission levels are tied to a Qualifying Assets balance, so the cheapest rates require 1 million USD or more
