What Firefly III does best

  1. Self-host a personal finance ledger under the AGPLv3 open-source license rather than using a hosted budgeting app.
  2. Track accounts and transactions with double-entry bookkeeping, budgets, categories, tags, recurring transactions, subscriptions, piggy banks, rules, and reports.
  3. Use the JSON REST API with OAuth2 or personal access tokens for dashboards, automations, and personal analytics.
  4. Optional event webhooks for transaction create, update, and delete events when enabled through environment configuration.
  5. Import transaction data through the separate Data Importer using CSV, CAMT.052, CAMT.053, GoCardless, SimpleFIN, Lunch Flow, or Enable Banking.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
