WalletWealthBuilder

Project Overview

WalletWealthBuilder is a free, open-source personal finance application built to provide financial clarity without selling financial products. The philosophy is simple: everyone deserves access to quality financial management tools without hidden agendas, upsells, or data harvesting.

The application covers the core pillars of personal finance management: a central dashboard for at-a-glance financial health, category-based budgeting, goal setting with progress tracking, and detailed reports with PDF export capabilities.

Technical Architecture

The application follows a clean separation of concerns with a dedicated frontend and backend:

• Frontend (React): A TypeScript-based React single-page application handles all user interactions, data visualization, and report generation. The component architecture makes it easy to extend with new financial tools.
• Backend (Express/Node.js): A Node.js API built with Express serves as the data layer, handling authentication, CRUD operations for accounts, transactions, budgets, and goals.
• Database: SQLite for local development (zero-config setup) with PostgreSQL and MySQL support for production deployments. The five core entities (User, Account, Transaction, Budget, Goal) model the complete personal finance domain.

Design Philosophy

The dual-database approach was intentional. SQLite makes it trivial for developers to clone the repo and start contributing immediately with no database server to install. For production, the same application seamlessly transitions to PostgreSQL or MySQL for the reliability and scalability needed in a real deployment.

Keeping the application open-source and free means no compromises on user privacy. There's no tracking, no ads, and no financial product recommendations. The tool exists solely to help people manage their money.

Deployment Options

The architecture supports flexible deployment: the Express backend can run on Render, Heroku, or AWS, while the React frontend deploys to Netlify, Vercel, or AWS. The database tier can use AWS RDS, DigitalOcean Managed Databases, or Railway for managed PostgreSQL.
