FinTrack

FinTrack is an open source, event-driven personal finance platform for tracking accounts, transactions, budgets, and spending. It is built with Java 21 and Spring Boot, split into an API service and a background worker that communicate through Amazon SQS, with PostgreSQL for data, Redis for rate limiting, and S3 for file storage.

Users create financial accounts with opening and current balances, record income and expense transactions, and let FinTrack categorize them automatically using configurable matching rules — with manual overrides when the rules get it wrong. Monthly budgets per category show on-track, warning, and over-budget states and generate persistent notifications, while summaries compare income against expenses and break spending down by category and account. CSV imports are handled as restartable batch jobs that skip invalid rows and produce a downloadable report of anything rejected.

FinTrack sits where Mint, YNAB, and Monarch Money sit: a personal hub for accounts, budgets, and spending insight. The difference is that there is no bank syncing and no subscription — you import transactions as CSV files, and either run the whole stack locally with Docker Compose and LocalStack or deploy the included Terraform-defined environment to your own AWS account. A React web client is included for day-to-day use.
