The gist

OpenBB is an open-source data platform for financial markets. Built by the OpenBB community, it solves data fragmentation by helping data engineers and quantitative analysts integrate disparate proprietary, licensed, and public data sources. It acts as a single access layer for use in downstream applications like AI copilots, research dashboards, and custom analytics environments.

What it does

Integrate financial data from numerous public and private sources.
Access data through a Python library, a command-line interface (CLI), or a REST API.
Retrieve historical data for stocks, options, crypto, and fixed-income assets.
Connect to the OpenBB Workspace for data visualization and analysis.
Serve consolidated financial data locally via a self-hosted FastAPI server.

How it works

Users install the open-source Python package or CLI to their local environment. By writing simple commands or Python scripts, they can pull data from various sources into a standardized format, typically a dataframe. The platform acts as a "connect once, consume everywhere" infrastructure layer. It is distributed as a free tool under an AGPLv3 license and can be self-hosted to power other applications.

Best for

Data engineers, quantitative analysts, and financial developers who need a unified, programmatic way to access and consolidate financial market data for analysis, backtesting, or building custom applications.
