Best open-source alternatives to YNAB

Firefly III is a self-hosted personal finance manager aimed at people who want control over their money without uploading financial records to a cloud service. It is presented as free and open source software and is intended for users who are comfortable running and managing their own server-based applications. The application helps users track income and expenses, organize transactions with budgets, categories, and tags, and generate financial reports. It also supports recurring transactions, rule-based automation, piggy banks for goals, and a REST JSON API for broad external integration. The README emphasizes that the software is isolated by default and only contacts external servers when explicitly configured to do so.

Actual is a local-first personal finance and budgeting application aimed at people who want to manage money on their own devices while still keeping data synchronized across devices. The README describes it as free and open source, with a NodeJS-based core and a synchronization layer that moves changes between devices without much manual effort. It can be deployed in several ways, including one-click hosting, managed hosting, self-hosted Docker, or as downloadable desktop apps for Windows, Mac, and Linux. The project also provides community documentation for budgeting, account management, migration, and contributor guidance, suggesting it is designed both for end users and for people interested in extending or maintaining the software.

The project supports day-to-day bookkeeping tasks such as recording transactions, importing financial data, searching and filtering bills, and visualizing spending patterns through built-in charts and custom queries. It also includes mobile and desktop-oriented interfaces, PWA support for a native-like mobile experience, and features for localization, security, and broad data import/export interoperability.

It presents itself as a fully working personal finance application aimed at people who want to manage money and wealth data in a self-hosted environment. The README emphasizes that the app can be run with Docker for self-hosting, while also providing local development instructions for contributors. It requires Ruby, PostgreSQL, and Redis, and it includes optional demo data plus default demo credentials for trying the app locally. The project is distributed under AGPLv3 and is positioned as a continuation of the original codebase rather than a separate commercial product.

WYGIWYH is a self-hosted personal finance tracker aimed at people who want a simple, principle-driven way to manage money without traditional budgeting constraints. It focuses on tracking what is earned and spent within a month while keeping savings separate and untouchable for future months. The project is built for users who need more than a spreadsheet, especially those handling multiple currencies, accounts, and investments. It supports automation-oriented workflows through an API and configurable transaction rules, and it is run as a web application with Docker-based deployment. The README also indicates support for local operation and an admin account setup flow, suggesting it is meant for individual or household financial management rather than enterprise finance.

It positions itself as an alternative to Mint and focuses on monthly budgeting, transaction tracking, and organized management of both accounts and assets. The project supports importing transactions from CSV files, syncing with financial institutions through providers such as SimpleFIN and LunchFlow, and automatically categorizing transactions using a machine learning model and user-defined rules.
