Show HN: Open-source expense and budget tracker with SQL API for AI agents (github.com)

An open-source expense and budget tracker has been launched, enabling self-hosting and full control over financial data using Postgres. This tool is significant for the AI/ML community as it features a SQL Query API, allowing AI agents to analyze and manage financial data through simple HTTP requests. The design of the tracker emphasizes a minimal table structure to reduce misuse, making it ideal for integration with Large Language Models (LLMs) like Claude Code or Codex. Users can deploy the application on their own servers, ensuring data sovereignty while utilizing a user-friendly interface for tracking budgets and transactions in various currencies. The integration process involves generating an API key for the AI agent, which can then process inputs like screenshots and CSV files to update financial records automatically. The built-in UI allows for easy monitoring of spending and budget planning, highlighting the tool's capabilities not only for personal finance management but also for AI-driven analysis and automation. This innovation enhances the potential of AI in personal finance, empowering users to leverage technology for better financial insights.
