What is Firefly III?

Firefly III keeps track of your income and expenses so you can see where money goes and plan to spend less. You record transactions in accounts and organize them with budgets, categories and tags, then use its many financial reports to look back over months or years. Separate tools import data from banks and files. It runs on your own server, in Docker or on Kubernetes, and several hosts offer it as a paid service, some of which share revenue with the developer. Translations cover 31 languages.

Good fit if

  • You want a detailed record of personal finances on your own server, with no cloud account and no AI features.
  • You enjoy categorizing transactions and reading reports to understand your spending.

Look elsewhere if

  • You want lighter envelope budgeting that works on your devices first: Actual Budget.
  • You mainly track investments: Ghostfolio.
