DetailsVisit site

Firefly III

DetailsVisit site

Firefly III is a free, open-source, self-hosted personal finance manager for people who want control over their own budgeting, accounts, transactions, categories, tags, reports, imports, API access, and automation.

The main tradeoff is operational responsibility: users must host it, secure it, back it up, update it, and configure imports themselves.
