Straight talk

Where each one wins

What Mint and YNAB do well

  • Automatic bank and card syncing, no manual imports
  • YNAB's budgeting method is genuinely excellent
  • Mobile apps that make logging easy
  • Low friction to get started

Where Mint or YNAB may still be the better fit

  • You want automatic bank sync with zero manual work
  • You rely on YNAB's specific budgeting methodology
  • You want a polished mobile app above all
  • You don't want to import statements yourself

Our honest take: if automatic bank sync and a great mobile app are essential, YNAB is worth its subscription. If you'd rather not hand your bank credentials to a third party and you want your financial history to be yours forever, Firefly III is the honest alternative.

Frequently asked questions

Does Firefly III connect to my bank automatically?

Firefly III is designed for privacy and does not connect to your bank by default. You import transactions via CSV or OFX files. This keeps your banking credentials off the internet, but it means a manual import step rather than Mint-style automatic syncing.

Is Firefly III good for business bookkeeping?

Firefly III is built for personal finance and is excellent for tracking spending, budgets, and net worth. For full business accounting with invoicing and tax reporting, ERPNext is a better fit.

Will Mint shut down?

Mint announced it is winding down and directing users to Credit Karma. Many people are looking for a replacement because of that. Firefly III is self-hosted, so it cannot be shut down by a vendor.
