ExpenseOwl: Personal Finance, Without the Bloat

Managing your expenses shouldn’t require a degree in accounting—or a subscription to yet another SaaS platform. Most expense trackers, from YNAB to Spendee and MoneyWiz, are packed with features you’ll never use, lock your data behind paywalls, and often require cloud sync for even the most basic functionality. ExpenseOwl is different. This open-source, self-hosted app is designed for one thing: making it dead simple to track your spending, visualize your habits, and own your data—no strings attached.
