OpenBB is an open-source financial data and analytics platform designed to give developers and analysts a unified way to access market and investment information. It connects financial datasets and providers through a common interface, reducing the need to build separate integrations for every source and making data easier to use in notebooks, applications, dashboards, and research workflows.

The platform is aimed at quantitative researchers, analysts, fintech developers, and teams building financial tooling. Its modular data layer and APIs can be combined with custom analytics or AI applications, making OpenBB useful as infrastructure for market research, investment analysis, financial agents, and internal tools that depend on consistent access to multiple financial data sources.
