Expense Budget Tracker is a self-hosted, open-source personal-finance application for budgeting, tracking transactions and balances, transferring funds between accounts, and reporting across currencies. It runs on PostgreSQL and provides a web interface for managing budgets, transactions, accounts, and workspaces. The project includes a hosted MCP server and an Agent API. Compatible MCP clients can inspect workspace schemas, run restricted read queries, and, with the required write scope, execute approved data changes. The HTTP SQL API uses API keys and a flat table structure so AI agents can query and analyze financial data or import transactions from screenshots, CSV files, and PDF bank statements. The repository provides a Docker-based quick start that runs PostgreSQL, migrations, the web application, and a worker. The project is fully open source and designed for deployment on the user's own servers.

Securo is an open-source, self-hosted personal-finance manager developed by securo-finance. It keeps financial data on the user's infrastructure and provides multi-account management, transaction search and CSV export, imports for OFX, QIF, CAMT, and CSV files, categorization rules, recurring transactions, budgets, savings goals, asset valuation, reports, multi-currency conversion, and optional bank synchronization through Pluggy, Enable Banking, or SimpleFIN. The application supports multiple users, passkeys, TOTP two-factor authentication, and OIDC single sign-on. An optional AI-agent profile adds self-hosted chat over Securo data, tool use through MCP, multi-provider support, and a per-agent RAG knowledge base. It can be deployed with Docker or Podman, uses a FastAPI and PostgreSQL-based stack with Redis and Celery, and is licensed under AGPL-3.0.

TaxHacker is a self-hosted AI accounting application for freelancers, independent developers, and small businesses. It processes receipt photos, invoice PDFs, bank statements, and other documents with a configurable LLM, extracting dates, merchants, amounts, taxes, product names, and line items into a structured, Excel-like database. It can categorize transactions, split invoice items into separate transactions, and use custom fields with user-defined prompts; supported model backends include OpenAI, Google Gemini, Mistral, and local OpenAI-compatible endpoints such as Ollama, LM Studio, vLLM, and LocalAI. The application detects document currencies and converts transactions using historical exchange rates from the transaction date, including cryptocurrency support, and provides filtering, multi-project organization, import/export, and custom categories. The repository describes the project as being in early development and advises using it at one's own risk.

Kharcha is a private spending ledger for Android and other Expo-supported platforms. It parses bank transaction SMS messages or pasted messages on the device, extracts debit or credit amounts and merchant details, preserves each raw message beside the parsed entry for review and correction, and stores the ledger locally in SQLite. Users can add categories, budgets, and insights; the Android reader scans messages only from enabled sender IDs, filters common OTP and promotional patterns, and uses heuristic parsing with uncertain results sent to review. The app works without an account or backend. An optional backup flow encrypts the ledger on the device with AES-GCM and sends only ciphertext to a small Render API backed by Postgres; the recovery code contains the access token and encryption key. iOS and web versions support manual or pasted entries, while general inbox reading is Android-only. The project is MIT-licensed. Its README notes that parsing may miss or misclassify messages, the Android build has not yet been smoke-tested on a physical device, and Google Play distribution using READ_SMS requires policy approval.

OpenStock is an open-source stock market web application developed by Open Dev Society. It provides stock search, watchlists, company profiles and financial information, market news, TradingView charts and market widgets, personalized alerts, and support for more than 30 international exchanges. It is a market-information app rather than a brokerage, and data may be delayed according to provider limits. The application uses Next.js, React, TypeScript, Tailwind CSS, shadcn/ui, Better Auth, MongoDB, Finnhub, and TradingView widgets. Inngest runs background workflows for AI-personalized welcome emails and scheduled news summaries; optional sentiment insights use Adanos across sources including Reddit, X.com, news, and Polymarket. It can run locally or with Docker Compose, using MongoDB for persistence and Finnhub credentials for market data. The repository is licensed under AGPL-3.0, including source-release requirements for modified, redistributed, or deployed versions.
