Aurum — a self-hosted personal finance operating system: cash flow, net worth tracking, budgets, goals, recurring payments, reports, proactive alerts, and a compound-interest returns calculator, all bilingual (RU/EN) and mobile-first. Ships as a three-container Docker Compose stack (Postgres + FastAPI + nginx-served React frontend). See README.md for setup and CONTRIBUTING.md for development.
