Track income, recurring expenses, and multi-currency assets with WYGIWYH, a self-hosted personal finance platform built on a strict cash-flow principle that preserves monthly savings while exposing spending patterns. Users can aggregate holdings across checking accounts, physical cash reserves, crypto wallets, and custom asset models with automatic foreign exchange rate calculations. The transaction engine executes automated adjustment rules to normalize merchant names, apply category tags, and calculate split costs on every purchase. Investors can schedule dollar-cost averaging portfolios to monitor accumulation performance and price averages over extended investment horizons. Interactive dashboards provide monthly breakdown grids, calendar views of pending recurring bills, and multi-year net worth trajectories. Financial analysts can export transaction journals to CSV, automate data synchronization through REST webhooks, or query accounts with AI agents via the Model Context Protocol. Customizable notification triggers alert account owners to payment due dates and anomalous spending spikes across monitored accounts. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GNU AGPL v3.0 licensed.

With over 24,000 GitHub stars and active development since 2014, Firefly III is the self-hosted personal finance manager that gives you complete control over your financial data without ever contacting external servers.

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.

Allocating every incoming dollar into purposeful spending and savings buckets before transactions occur, OpenBudgeteer gives households complete financial control through a self-hosted zero-based envelope budgeting platform. Users can organize expenditures into customizable bucket hierarchies, grouping everyday living costs, debt repayments, and sinking funds into distinct categories with target balances. Financial planners can import bank statement files via flexible CSV mapping profiles that parse transaction descriptions, clean up merchant strings, and auto-assign records to corresponding expense buckets. The transaction registry provides split-transaction functionality, allowing shoppers to divide a single department store receipt across grocery, household, and clothing envelopes with exact currency precision. Interactive progress bars display bucket health throughout the billing month, signaling when spending velocity threatens allocated limits and calculating suggested contributions for forthcoming paychecks. Advanced forecasting reports plot multi-month net worth trajectories, track category expenditure patterns, and calculate burn rates against long-term retirement and emergency savings goals. Account balances synchronize across multiple physical checking accounts, credit cards, and cash wallets, ensuring total bucket balances reconcile perfectly against real bank reserves. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL v3 licensed.

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.

When your bank balances, brokerage holdings, credit cards, loans, and crypto wallets sit scattered across a dozen institutional portals, Sure brings your entire financial life into one private, self-hosted wealth management workspace. You can track checking, savings, real estate, vehicles, and multi-currency investment portfolios while monitoring real-time net worth charts and thirty-day account sparklines. Automated account synchronization connects through Plaid, SimpleFIN, Enable Banking, Lunch Flow, SnapTrade, Questrade, and native Bitcoin, EVM, or Solana wallet integrations, alongside manual CSV, XLSX, and PDF statement imports. A built-in statement vault parses date ranges and opening or closing balances directly from uploaded PDF statements in seven languages to reconcile your ledger against bank records. Day-to-day transactions support nested subcategories, merchants, tags, receipt attachments, and automated categorization rules with regular expression matching. Monthly budgets let households run shared family budgets alongside individual member budgets while automatically excluding 401(k) and IRA retirement contributions from spending limits. Portfolio tracking pulls market prices from Yahoo Finance, Tiingo, Twelve Data, and Alpha Vantage, calculates or locks per-share cost basis, and labels buys, sells, and dividends. An optional AI assistant sidebar answers natural-language questions about your cash flow and spending habits. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Budget Board is an open-source personal finance dashboard built to replace Mint by unifying checking accounts, credit cards, property assets, monthly category budgets, and long-term savings goals under your own roof. Households can connect their financial institutions through SimpleFIN for North American banks or LunchFlow for international accounts so balances and daily transactions sync automatically on a configurable schedule. If you prefer offline statement management, the bulk CSV importer parses custom date and amount formats while mapping rows directly to your accounts. Once transactions arrive, you can train the built-in machine learning auto-categorizer on your historical spending with a customizable confidence threshold, or define deterministic rules that match merchant descriptions, dates, and amounts. Monthly budget cards track hierarchical parent and child categories against spending limits, and the goals workspace calculates progress toward paying down debt or building an emergency fund. Interactive trends charts let you filter cash flow, net worth, and category breakdowns across custom date ranges and accounts. Multi-user households can secure their financial records with local two-factor authentication or external OpenID Connect single sign-on, alongside localized date and currency formatting in English, German, French, and Simplified Chinese.
