Where Open Accountant wins
What Firefly III doesn't offer.
- ✓Zero AI capabilities — all categorization is manual rules with no learning

- ✓Import process is widely reported as fragile — configurations not remembered, multiple breakages
- ✓PHP/Laravel stack limits the contributor pool compared to TypeScript or Python projects
- ✓UI is functional but dated compared to modern finance apps
- ✓No built-in bank sync — the separate data importer tool is unreliable

Who should stay with Firefly III
