FlyBudget

FlyBudget ships Electron desktop apps for Windows 10 and 11, macOS 12 and later (Apple silicon and Intel), and 64-bit Linux (.deb, AppImage, and ARM builds). The same app can be self-hosted with Docker and opened from any browser, with a layout adapted for phones. There is no separate native mobile app.

Yes. You can import CSV files from any bank with automatic duplicate detection, or sync transactions automatically through SimpleFIN or Plaid. A dedicated importer for YNAB and other budgeting apps is on the roadmap but not available yet.

Plaid and SimpleFIN secrets are encrypted with AES-256-GCM under a key held by your operating system: Windows DPAPI, macOS Keychain, or the Linux secret service. A copied database file alone gives no bank access, and your financial data only leaves your machine when bank sync runs.

Yes. The desktop app is local-first, so your budget file lives on your computer. The self-hosted version keeps showing your budget if the server connection drops, queues new transactions, and reconnects on its own. Transactions added on a phone without a connection are saved as soon as it returns.

You can download a full backup of your budget at any time and restore it in one step, or export your data as CSV. Self-hosters get versioned images for amd64 and arm64, and the self-hosting guide covers HTTPS setup, backups, and updates.
