OpenBB — Open-Source Investment Research Platform

Introduction

OpenBB is an open-source financial research platform that aggregates market data from over 30 providers into a single Python interface. It replaces expensive Bloomberg-style terminals with a free, extensible toolkit for equity, crypto, macro, and alternative data analysis.

What OpenBB Does

• Provides a unified API to pull equity, options, crypto, forex, and macro data from multiple providers
• Offers both a CLI terminal and a Python SDK for programmatic access
• Supports charting, technical analysis, and portfolio optimization out of the box
• Enables custom dashboard creation via OpenBB Hub and Jupyter integration
• Allows community extensions through a standardized provider interface

Architecture Overview

OpenBB Platform is built on a router-based architecture where each data domain (equity, crypto, economy) exposes standardized endpoints. Providers are pluggable modules that implement a common interface, returning normalized Pydantic models. The CLI wraps the SDK with rich-text output and interactive menus.

Self-Hosting & Configuration

• Install via pip or conda in a Python 3.9+ environment
• Configure API keys for premium data providers in ~/.openbb_platform/user_settings.json
• Deploy OpenBB Hub locally with Docker for team-shared dashboards
• Use environment variables to manage secrets in CI/CD pipelines
• Extend with custom providers by implementing the Provider abstract class

Key Features

• 30+ integrated data providers including Yahoo Finance, Polygon, Intrinio, and FRED
• Built-in charting with Plotly for interactive financial visualizations
• Quantitative analysis tools: DCF, CAPM, Monte Carlo simulations
• Portfolio optimization with risk metrics and backtesting
