OpenBB

Open source

Open-source investment research platform and Python toolkit for market data.

Overview

OpenBB is an open-source investment research platform and Python toolkit that unifies many data providers behind one interface.

Data providers are configured with the operator's own API keys, so coverage depends on which provider subscriptions are supplied. The platform includes a Python library, a REST API, a workspace interface, and a plugin architecture for adding data sources. It is a research and analysis layer rather than a data source itself.

Common use cases
