My accounting data lives on my Mac. Not in some cloud.
As a freelancer, I spent a long time looking for a tool that combines invoicing, time tracking, and taxes without a subscription and without storing my financial data on someone else’s servers. I couldn’t find one. So I built it myself.
Midnight is an open-source app for freelancers and self-employed professionals in Germany:
- Invoices as PDF, XRechnung, or ZUGFeRD
- Time tracking with projects, budgets, and one-click billing
- Income, expenses, and receipts tailored to German EÜR accounting
- Tax forecasts for the current year
- An MCP server that allows AI agents to work directly with your own data
Everything runs locally in an SQLite database. Built with Rust, Tauri, and React.
