Monize

Monize is a money manager you run yourself, built to replace Microsoft Money and Quicken, which stopped getting updates long ago. Checking, savings, credit cards, loans, mortgages and investments all live in one place, along with transactions, categories, payees, budgets, bills and reports — no more splitting your money across several apps. It has 256 stars on GitHub, and the author — who kept his own books in Microsoft Money for over 30 years starting in 1995 — only published it after moving all three decades of his data over intact.

It is pretty complete: ten account types, balance trends and a 90-day forecast; transactions support splits, transfers, recurring entries and rule-based auto-categorization; investment accounts show holdings and price trends; the loans page includes a repayment simulator; there are 46 reports, plus custom ones. There is also an AI assistant you can just ask about your own money — spending habits, cash-flow forecasts for the months ahead — and it can connect to outside AI clients over MCP so they can look up your accounts too.

There are two ways in: if you do not want to install anything, open the live demo — the login is already filled in, click “Try Demo” and poke around; demo data resets every day at 04:00 UTC. To use it long-term, self-host it with Docker and PostgreSQL; the project ships a production Compose file and Kubernetes configs, and your data stays on your own server.

One honest warning: the author says right on the repo home page that he is not a professional programmer and cannot personally guarantee the code’s safety. This is real money, so run your usual flows through the demo first, back everything up before going live, and do not move your entire finances over on day one.
