OpenBB

OpenBB is an open-source financial data platform designed as a modern alternative to expensive proprietary terminals like Bloomberg. It provides a unified interface to access market data, economic data, fundamental analysis, technical analysis, and portfolio management tools.

Built with Python, OpenBB integrates with dozens of financial data providers and supports AI-powered workflows via its agent-friendly API. It runs as a web application or can be used programmatically, making it suitable for individual investors, quants, and enterprise teams alike.

With over 64,000 GitHub stars, OpenBB is the most popular open-source financial terminal. It supports extensions for crypto, forex, equities, fixed income, macroeconomics, and more — all customizable and self-hostable.
