Budgeting that actually keeps score

Every dollar allocated. Every transaction categorized. No surprises.

Envelope budgeting

Allocate every dollar of income to a named envelope — Rent, Groceries, Fun Money. You can only spend what's in each envelope, making overspending structurally impossible.

Offline-first, always yours

All data lives in a local SQLite database on your machine. No cloud sync, no account, no subscription. Your financial history is yours — export or back it up however you want.

Multiple accounts, one view

Track checking, savings, credit cards, and cash in one place. Import transactions from bank CSV exports, reconcile against statements, and analyze spending by envelope.

Built on honest principles

No dark patterns. No lock-in. No surprises.

Windows-native WinUI 3

Built with WinUI 3 and Windows App SDK for a modern, fluent Windows experience — not a web app wrapped in Electron. Respects system theme, DPI, and accessibility settings.

Privacy first

Zero telemetry. Zero analytics. No network calls. NextLedger never phones home. Your financial data — transactions, balances, budgets — never leaves your machine.

Clean Architecture

Built with Clean Architecture and MVVM. The budget engine is fully unit-tested and separated from the UI. SQLite for durability, C# for type safety, .NET 9 for performance.
