Econumo

Econumo lets you take control of your personal finances by running the whole system on your own server. It handles expense tracking, budget management, and recurring transaction automation so you don't have to rely on third-party cloud services. The tool supports multiple accounts, categories, and scheduled payments, making it a solid choice for anyone who wants to automate their billing workflows without sharing financial data.

The application is built with PHP and JavaScript, uses MySQL or PostgreSQL for storage, and runs in a Docker container for easy deployment. You can manage transactions, set up recurring bills, and categorize spending with tags. It also provides basic reporting to see where your money goes each month. Econumo integrates with nothing out of the box, but its scheduled transaction engine can simulate automated billing reminders.

This project is ideal for privacy-conscious individuals or small households that want to automate bill tracking without a subscription fee. It is open source under the MIT license and completely free to self-host. The latest stable release is v0.35.5, and the documentation lives on the project's GitHub wiki.
