Actual Budget is an open-source personal finance application that stores all financial data locally on the user's device using a SQLite database, enabling offline access and complete data ownership without cloud dependency. It packages the entire application stack into Docker containers for one-click deployment on any hosting platform with container support, and connects to over 10,000 financial institutions through the Plaid API to automatically sync account balances, transactions, and investment data.
The application implements a monthly budget model that tracks spending against category limits with real-time balance calculations and overage alerts, while applying user-defined categorization rules to incoming transactions in real-time using pattern matching on merchant names, amounts, and descriptions. It answers natural-language questions about account balances, spending, and investments by analyzing local financial data through an integrated AI assistant, and builds the user interface as a client-rendered React single-page application that communicates with the backend through REST API calls.
The system supports setting spending limits per category and tracking actual spending against those budgets, comparing spending over time and highlighting overages. Users can link bank accounts, investments, and crypto from multiple institutions to monitor total net worth in one place, add accounts through custom forms or import them from CSV files, and search transactions by date, account, category, or merchant. The application populates itself with sample financial records so new users can explore features without entering real data.
