Helius is a private personal finance tracker for your terminal. It shows you where your money went and where your balance is heading.
Transactions
It opens as a full-screen app you drive from the keyboard. Record income, expenses and transfers as they happen, or import statements from your bank, then keep it all in order with categories, budgets and reconciliation.
Forecast
Then it looks ahead. Helius forecasts your cash flow from your regular income and bills, shows what’s due next, and lets you plan one-off items and goals. Scenarios let you set a what-if beside your baseline and see the difference before you commit.
Private
Your finances stay on your own computer. Helius keeps everything in a single database file there, and it’s open source under the AGPL-3.0, so you can read exactly what it does. It runs on Windows and Linux (x86_64) or in Docker, with direct commands and JSON output if you’d rather script it.
