Quicken is the long-running personal-finance app for budgeting, tracking accounts and investments, and watching net worth over time, with bank-download and auto-categorization that pull years of transactions into one place. The pain is that it moved to a subscription where your access is tied to paying - let the plan lapse and you lose the connected features that make it useful - and it stays a Windows or Mac desktop product whose data lives in a proprietary file that is awkward to move anywhere else. The open source options here put money tracking back under your control: self-hosted or local-first, with your financial history in open formats on your own machine or server, readable whether or not you ever renew anything.
Actual Budget is a local-first personal finance app built around envelope budgeting. It runs entirely on your device, so it keeps working regardless of your network connection, and your data stays on hardware you control rather than a hosted account.
Firefly III is a free personal finance manager you run on your own server to track income and expenses. It is fully self-hosted and isolated, and it will not contact external servers until you explicitly tell it to, so your records stay off the cloud.

Ledger is a double-entry accounting system accessed from the UNIX command line.

It reads the files and generates output, with no other database or stored state.
Beancount is a double-entry bookkeeping language for recording financial transactions in plain text files.

OpenFisca-France encodes the French tax and benefit system as a model for the OpenFisca engine. It lets analysts and developers run microsimulation calculations, work with legislation as code, and query French rules without writing the model themselves. The working language of the rules is French.
OpenFisca Core is the engine behind OpenFisca, a microsimulation framework for modeling tax and social benefit systems as code. It supplies the shared rules and computation machinery that country packages, such as OpenFisca-France, build on top of, so a national tax-benefit model does not have to be written from scratch.
