Firefly III

Firefly III is the Den’s personal finance manager — a self-hosted tool for tracking accounts, transactions, and where the money actually goes. It runs as a Docker container on the Den’s Engine (Zone 1).

It is the track-and-analyze kind of finance tool rather than the envelope-budgeting kind: it records and reports, with a strong API the enclave’s automation can reach. It is the Den’s personal counterpart to the organization’s Bursar (ERPNext) — separate books, separate world.
