Best alternatives to Firefly III in 2026
Firefly III is a free program you install yourself that plays the role of a personal accountant living on your own computer or server: you feed it your bank transactions and it tracks where your money goes, warns you when a budget is about to be blown, and shows the full picture across every account and currency — without your financial data ever touching a company's servers. Under the hood it's a proper double-entry bookkeeping system (the accounting method banks and businesses use), with multi-currency support, budgets, categories, tags, a rule engine that auto-categorizes recurring transactions, and a bank-data importer. It exposes a full JSON REST API for custom dashboards or automations. It's self-hosted via Docker and AGPL-3.0 licensed — there's no company behind it selling a paid tier.
