A privacy-first personal finance app with two-level accounts, multi-currency support, AI receipt recognition, and broad data import from formats like GnuCash and Firefly III.

ezBookkeeping is a self-hosted personal finance app built for people who want full control over their financial data without relying on cloud services like Mint. It's lightweight enough to run on a Raspberry Pi or any low-resource device, and it works across Windows, macOS, and Linux.
The bookkeeping features go well beyond basic income and expense tracking:
AI features stand out here. Receipt image recognition can parse a photo and populate transaction fields. There's also MCP (Model Context Protocol) support, which means it can integrate with AI agents and external tooling in ways most personal finance apps don't attempt.
The interface is optimized for both mobile and desktop, with PWA support for a near-native mobile experience and a dark mode option. Security is taken seriously: two-factor authentication, OIDC external auth, WebAuthn application lock, and login rate limiting are all included.
Multi-currency support comes with automatic exchange rate updates from multiple sources. Multi-timezone and custom date/number formats make it genuinely usable internationally.
Data portability is broad. You can import from CSV, OFX, QIF, GnuCash, Firefly III, Beancount, Camt.052, MT940, and more. That range makes migrating from another tool straightforward rather than painful.
Storage options include SQLite for simple single-user setups, or MySQL and PostgreSQL for anything more demanding.
