Roughly $1M of development work, open-sourced: Maybe Finance began as a $249/year commercial personal finance product before the company released it all. It aggregates bank accounts, credit cards, loans, investments, crypto, and real estate into a single net worth dashboard with historical trend charts - replacing the spreadsheet that usually glues a whole portfolio together. Transactions are categorized and tagged with rules, with merchant tracking and search across imported or synced activity; budgets track spending by category against plan; and the investment view follows holdings, cost basis, and returns across brokerage accounts. Multi-currency support converts accounts held in different currencies into a single reporting currency, bank synchronization works through Plaid where supported, and manual CSV import covers any institution. An optional AI assistant answers questions grounded in your own financial data. Because the app was built as a paid product with professional design before being open-sourced, its interface quality exceeds most community finance tools - and self-hosting means your balances and transactions are not monetized by a free app or gated behind an annual subscription. The stack is Ruby on Rails with Hotwire on PostgreSQL, licensed AGPL-3.0 and deployed via Docker. The original repository is archived; development continues in the community fork Sure, compatible with the same self-hosted setup.

After the bills are covered, how much is actually safe to spend? monetr organizes an entire budgeting application around that one question. Inspired by the defunct Simple bank, it budgets paycheck by paycheck rather than month by month. Funding schedules encode when you get paid - including multiple schedules per account and a weekend-exclusion option for deposits that land early - and every expense or savings goal is tied to one. monetr then calculates how much of each recurring obligation (rent, car payment, subscriptions, on any repeat interval) to set aside from each paycheck, so a large bill never has to come out of a single check. What remains after allocations is surfaced as Free-To-Use, and a forecasting timeline projects contributions, due dates, and leftover funds forward so low-balance periods are visible before they happen. Transactions arrive either as OFX uploads from your bank or automatically through a Plaid connection using your own API credentials, keeping balances and transactions synced without manual entry. The app is mobile-friendly and installable as a PWA on desktop or phone. Self-hosting via Docker Compose is completely free, with all source code public and your financial data on your own hardware.

Your net worth is scattered across banks, brokers, a pension, and a mortgage, and no single screen shows all of it at once. Aurelio Finance gathers those pieces on your own server: record each institution's cash and holdings as dated situations, then let later transactions roll them forward so today's balance always traces back to a photograph of what you held and the events after it. Every position is priced from the market with its cost basis, gain, and dividends, while the look through view opens your ETFs and funds to show real exposure by country, sector, company, and currency, so overlapping funds stop hiding concentration. Recurring investment plans, homes and other real assets, and the loans against them sit beside income, expenses, and your savings rate, and each financial goal shows the return it needs to be reached. When you want a second opinion, Ask Aurelio reads your own records, can search the web, and proposes changes as cards you confirm or reject, never silently editing your data. Its analysis mode goes further, letting an analyst and a confidant argue over your portfolio before a synthesis tells you what to look at first, and surviving ideas land on a watchlist that your totals never count. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Ditch the spreadsheet for good: Whisper Money is a privacy-first personal finance app you host yourself to see exactly where your money goes, without your data being sold or profiled for ads.

Spending pattern insights turn raw transactions into an honest picture of your habits, month after month.

If your money is split across a bank app, a brokerage portal, and a half-abandoned spreadsheet, YAFFA, a self-hosted personal finance application, gathers it into one ledger with budgets, scheduled transactions, and forecasts. Record withdrawals, deposits, and transfers across unlimited accounts, and split a single supermarket receipt across categories so it lands in both Food and Household.
