Live demo

Try it at finance-tracker-production-a51c.up.railway.app — the login page shows the shared demo credentials (username demo). The demo account comes seeded with four months of realistic transactions, budgets, and categories, and resets nightly.

Overview

A full-stack personal finance application for tracking accounts, transactions, and spending over time. The backend is a Flask API built on SQLAlchemy Core; the frontend is React with TypeScript. The whole stack runs locally with Docker Compose or deploys as separate services.

Highlights

Clean API boundary — the Flask backend exposes a JSON API consumed by the React app, so either side can evolve independently.
Environment-driven config — development, testing, and production configs selected by environment variables, with SQLite for local development and a production database in deployment.
Mobile-friendly — the dev server can bind to the LAN for testing the responsive UI on a phone.
Containerized — one docker compose up brings up the full stack.

Status

The source is private since it evolved alongside my real financial data, but the live demo above runs the full stack — Flask API, React frontend, and Postgres — and I’m happy to walk through the code on request.
